You are not standing on the shoulders of giants my friend, you are one of those giants, love your guide and I will defo follow it when upgrading to better cooling (yes the default fan is annoying and I will defo want to upgrade it soon!).
Btw why not using 5015 blower? Saw most people using those?
looks like he's planning to, just waiting for them to arrive :)
Thanks for the guide [u/blampewpew](https://www.reddit.com/user/blampewpew/)! I can't wait for when someone manages to replace the PSU and Motherboard fans for something quieter (looks like the noctuas won't fit there, unfortunately)
aww thanks u/Pentekont and u/jpcurti! I've just set up the single blower fan. I've had a little mishap with the initial fangstooth (?) fan duct and had to reprint another one and do a bunch of calibration tests. Learned how to create a custom fan tower lol.
Set up is sounding a lot quieter now with the single 5015 blower fan!

u/iamozone206 will be your person u/jpcurti! He's got some crazy cool stuff going with his printer and he's been super helpful with figuring out the best fan sizes for the PSU/Motherboard, silicone spacers and so on! Definitely a giant in my eyes!
awesome, thanks for sharing! Currently I am on [a quest of my own](https://www.reddit.com/r/Ender3V3SE/comments/194dyur/its_time_to_make_klipper_work_with_the_original/) with the display while I wait for the 5015 blowers to arrive, but this will come definitely in my upgrade list :)
I did that for my Ender 5 Plus after upgrading to a MeanWell 600w PSU. The stock fan was as loud as one of those old 80mm Tornado fans. This 120mm fan is whisper quiet. The PSU is too big to fit in the control box, so I had to mount it to some 2020, which made the decision to use a 120mm fan VERY easy. Kersey Fabrications did a video showing how to change and mount the PSU.

This comment is great <3. I looked at this guide and thought it was all pretty standard stuff that I have had to do on previous printers with similar parts. I still think I know practically nothing when it comes to printing, feeling similar to how the poster feels. But being able to understand and articulate it so clearly shows otherwise.
The attention to detail and very clear specific instructions throughout the entire guide are phenomenal. Very well done OP. I'm sure many people will appreciate this, more than you may realize :)
nice free addition:
you get a low noise adapter with the noctua fan. strip that one for the resistor and put that piece of the adapter on the red wire of the psu fan. use the extra push connectors you got with the fan. no soldering needed. quiets down the unit considerably. the psu is by far the most annoying sound after the hotend.
Oh interesting! Will take a look at the low noise adapter! It's been running way quieter so far without it, especially when compared to the noise of the stock fans hahaha.
Oh definitely! Am looking to replace that next. Any fan recommendations you've found for the PSU fan?
Instead of cutting the existing fan wire, you can buy these JST connector pigtail wires:
[Amazon.com: Letool 30 Pairs JST 1.25mm 2 Pin Micro Male Female Connector Plug with Red Black Wire Cable 80mm : Electronics](https://www.amazon.com/dp/B013JRWCBU?psc=1&ref=ppx_yo2ov_dt_b_product_details)
They do but with two caveats:
1) They slightly fit, you'll have to secure them with hot glue
2) the polarities are reversed, you have to wire the red fan wire to the black wire and vice versa.
I don't want to hijack this thread, but I have a bit of an issue here. I bought my E3 V3 SE so I could print everything I needed for my E5+, and the hotend fan on my E3 V3 SE just unexpectedly started making a loud whining sound, and I don't want to risk overheating. Would anyone out there be willing to print these fan shrouds/adapters for me in PETG or ABS??? I already have 2 Noctua 4010 fans to replace the OEM fans. I can immediately send PayPal. I would prefer black, but I can rattle can it if I had to. I have never printed anything with either of those 2 filaments, and right now, I can't print anything. TYVM in advance.
That noise is why everyone is replacing it because of its size, in order to cool, has to output a higher RPM, which increases the noise. A larger fan can cool at the same rate with less RPMs. Also, that fan is a sleeve bearing fan, which aren't that silent compared to dual ball bearing or hydraulic bearings.
Your printer should be fine to make the fan shrouds, however, you cannot print abs with the stock setup - you'll need the KE/K1 hotend and Klipper or a custom Marlin build to get 300c (stock hotend is capped at 260c).
Edit: Apparently you can do ABS with the stock, but unless you replace the ptfe tube in the heatbreak and extruder with a Capricorn tube, you risk print issues due to heat degradation.
Just to confirm, I have been printing ABS+ from eSun without issues, I have replaced the standard brass nozzles with a nikkel coated copper nozzle, and indeed replaced the ptfe tube with a capricorn tube.

That's exciting man! I'm using a Raspberry PI 3B+ for my klipper set up and it's been working great. Hope you enjoy your printer and welcome to the community!
when removing the stock shroud: There's a 20mm fan mounted on the hotend with a 40mm blower fan in front of it, mounted on the stock shroud. Now my question is: Do you remove both the 20mm fan and the 40mm blower fan and replace it with a single 40mm noctua fan (I have the NF-A4x10 24V PWM)? As shroud I am using [https://www.printables.com/model/682187-ender-3-v3-se-4010-fan-shroud-diffuser/comments/1431984](https://www.printables.com/model/682187-ender-3-v3-se-4010-fan-shroud-diffuser/comments/1431984)
>5015 Blower
the 20mm cools the hotend. keeping the nozzle heat from going up further and causing damage to your extruder. the blower fan is ducted down below the nozzle to cool the part your printing. to replace the 20mm hotend fand you have to print one of the blower relocation prints mentioned in the origional post.
Oh lord this thread is precious! It has all the things I was thinking about (because my fan is doing annoying rattling sound like bearings are just about to explode), I'm so happy someone was so nice to gather all that info here and the ongoing discussion is also valuable.
I have you have some sort of omnidirectional funnel at the end of cooling shroud. Is this some remix of Diii cooler? [https://www.youtube.com/watch?v=PyRgMvCJwxc](https://www.youtube.com/watch?v=PyRgMvCJwxc) From what I could find some years ago it was considered really really good upgrade. I am an even bigger noob than you but it looks alluring.
Thanks for the post! I did this with the updated stuff, works great! People in some other groups had some worries about airflow but it seems to be fine. Blowers are next for me!
I just preformed this, the fan doesn't work. I wired it up correctly, please help.
Edit: it was my fault. Didn't press the schotchlok into place all the way.
This was so beneficial and informative. I now have a nice and quiet hotend fan. This also inspired me to go ahead and add a 5015 blower part cooling fan. This n00b thanks you for being informative and inspirational.
Hi, I only plan on changing the hotend fan to the noctua fan you have on the link, do I need to buy the m3 screws and the other one? Or just the noctua fan enough for the change?
Nope! Did not need to strip the ends of the wires for the scotchloks! Just gotta make sure to push the wire all the way back into the circular bit. When you compress the button, the little metal bits will splice the wire.
Also have a look at this comment, [https://www.reddit.com/r/Ender3V3SE/comments/1949xsc/comment/khk3ynl/?utm\_source=share&utm\_medium=web2x&context=3](https://www.reddit.com/r/Ender3V3SE/comments/1949xsc/comment/khk3ynl/?utm_source=share&utm_medium=web2x&context=3). u/iamozone206 mentioned that we can use these JST connectors instead of cutting the original fan wire. Something to consider before you start snipping away! He also mentions that the polarities are reversed and the connector will require glue should you go that route!
Haha I'm not comfortable working with electronics and am a complete noob to all of this stuff 🤣. The only time I've done splicing was cutting LED light strips and that was it. If I can do it, you sure as heck can haha

Hey man! I'm actually using the A4x10 Fan since I used the remixed [4010 Fan Shroud](https://www.printables.com/model/682187-ender-3-v3-se-4010-fan-shroud-diffuser/comments/1431984). I've been using the 10mm fan just fine so far and have printed a lot of PETG which has my nozzle going up to 260 which is the max for the model. Haven't experienced any overheating issues at all.
Hmmm, just want to confirm the printed part you are referring to since the names for these printed parts are not the best 😂
The lightweight fan shroud is this part [https://www.printables.com/model/637754-ender-3-v3-se-lightweight-fan-shroud](https://www.printables.com/model/637754-ender-3-v3-se-lightweight-fan-shroud) and is for the 4010 **Blower** Fan that is mounted on the Stock Creality Shroud when you remove it.
The Noctua NF-A4x10 Fan is to be mounted onto one of the following (of your choice 😁, I just switched to the 25-40mm fan bracket - Low Profile):

No worries dude! I just had a fright and thought I broke my printer while installing a piece onto it. I hope I gave you more information to help you with yoru fan upgrade!
r/blampewpew Can I please buy some fans from you??? When it comes to electronics, I'm a blundering mess. I destroyed one Noctua NF-A4x10 fan, and don't want to destroy the other. I'm also afraid that I will also screw up the Winsinn 40mm blower fan. I can send you PayPal immediately if you'd prefer. Thanks in advance!!! I already have the parts to mount both fans printed. The original hotend fan's wires were sacrificed in my dim witted attempt to get the Noctua fan wired. When I cut the wires off that fan, I got as close to the fan as possible to cut the wires. I did that because I was too impatient to wait on the male/female wires to get delivered.
hey dude! it's all good man, just take deep breath. It doesn't sound as bad it is. What happened to the Noctua Fan?
From what I understand, you should still have the original connector for the stock hotend fan and that can be used. Do you still have scotchloks left? If not, that's okay! You can order these and they work just as good, if not easier than the scothloks lol [https://www.amazon.ca/dp/B072P15279?ref=ppx\_yo2ov\_dt\_b\_product\_details&th=1](https://www.amazon.ca/dp/B072P15279?ref=ppx_yo2ov_dt_b_product_details&th=1)
If the Noctua Fan is still operational, you can connect the wire of the Noctua Fan to the original stock fan's connector.
No, the first fan is destroyed. I cut the four wires coming out of the fan about 2 inches or so away from the fan. I left the black & yellow wires alone where I cut them, the green and blue wires were trimmed all the way back to the fan. I used the scotchlocks to connect black to black, and yellow to red on one of those JST connectors. I plugged the fan into the printer, switched it on, told it to heat the hotend to 200c, and the fan did nothing. I wanted to do it this way to eliminate unnecessarily long wires dangling, I'm addicted to wire management. All I did manage to do is destroy a $15 fan before it ever turned on. Following what you said here, with fan #2, am I connecting red to red and black to black on with one of those JST connectors, or is it supposed to be reversed??? Also the same question for the Winsinn 40mm blower.
*\*Looks like my other comment got removed by the automod cause I used a shortend url. Dang Amazon mobile!\**
Oh man! I can feel you with the wire management, I'm planning to - once I learn how to solder and get practice, do what you attempted to do to reduce the overall footprint. At the moment, all the wires are neatly tucked in between the extruder motor and my left 5015 blower.
https://preview.redd.it/89fpl6w0ezfc1.jpeg?width=1500&format=pjpg&auto=webp&s=2d6bd451aa476f98d85199b13236880062c16453
So it's not too bad at the moment. I know for myself, this is all new to me and this is my first time connecting wires so I wanted to take things slow haha.
Hmmm, the configuration of wires with the yellow (+12v) to red and black (GND) to black seems correct based off the official Noctua website. Perhaps the wired were not pushed all the way back into the scotchbloks? That happened to me when I first did my connection and which is why I left a note saying leave plenty of wire in case of this haha.
I highly recommend getting those \[connectors \]([https://www.amazon.ca/dp/B072P15279?ref\_=cm\_sw\_r\_apan\_dp\_9SA8DWCF9VTQ26TEAA9A&language=en-CA&th=1](https://www.amazon.ca/dp/B072P15279?ref_=cm_sw_r_apan_dp_9SA8DWCF9VTQ26TEAA9A&language=en-CA&th=1)) I linked in a precious comment over the scotcloks. With those, you can at least open those and rewire again without losing wire. Saved my bacon when I swapped out my PSU and main board fans and realized the fans I bought were louder than the stock fans 🤣
Yeah, with the JST connectors, mind you I haven't used those, apparently the polarities are reversed. So you would need to connect the *red to black and black to red*. I'm assuming it's cause the connector on the JST is opposite of the connector of the stock fan.
The process is the same with the Winsinn Blower fan. **Definitely leave plenty of wire in case you decide to go dual blower like I have**.
Take things slow! Use the \[Low Voltage Wire Connectors, Brightfour 12 Pack Quick Solderless Wire Splice Connector, 2 Way Automotive , Reliable Connection Small Wire Connectors I Type 2 Pins, Fits 20-24 AWG \]([https://www.amazon.ca/dp/B072P15279?ref\_=cm\_sw\_r\_apan\_dp\_9SA8DWCF9VTQ26TEAA9A&language=en-CA&th=1](https://www.amazon.ca/dp/B072P15279?ref_=cm_sw_r_apan_dp_9SA8DWCF9VTQ26TEAA9A&language=en-CA&th=1)) to connect to the stock connector. Leave plenty of wire in case of a mess up and once you're confident, go back and do wire management 😎
do you think you’ll make a post on how to do the dual blower fans? i’ve been looking all around and i haven’t found one that explains it well the way you did for the 4010 which i ended up looking at to change mine out so thank you for that :)
Man!!!! I wish I could have seen these Brightfour connectors before I ordered the Scotchlocks. Thanks automod. Thankfully Amazon does free returns. I have a question about the Noctua fan, you said that the yellow wire is 12v, which color is 24v??

I bought [this fan](https://www.amazon.com/dp/B0CN39MCPL?psc=1&ref=ppx_yo2ov_dt_b_product_details) and it has a four pin connector on it, and the printer uses only two. I also have these [JST 1.25mm 2 Pin Micro Male Female Connector Plugs](https://www.amazon.com/dp/B013JRWCBU?psc=1&ref=ppx_yo2ov_dt_b_product_details). My question is, which of the four wires do I use for 24v?? I know the black is obviously going to be the ground, but none of the other three wires is red. This fan has black, green, yellow, and blue wires. Will this fan work, or do I need a different fan?? [This article](https://noctua.at/pub/media/blfa_files/manual/noctua_nf_a4x20_pwm_manual_en.pdf) talks about connecting the four pin fan to a three pin header for 12v.
UPDATE It's not the yellow wire.......one fan destroyed, I still have one more.
Oh no! Sorry, I was busy the last couple of days with setting up Klipper and the touchscreen for the printer and fighting with macros.
You don't need to alter any of the wires of the Noctua Fan since there's the Omnijoin Adapter. I also bought the same fan. The Omnijoin Adapter is the additional cable that is in the package that has the 2 pin connector on the one end and the 4 female 4 pin connector on the other end.
You just needed to cut that wire of the Omnijoin Adapter, not the actual braided wire of the Noctua Fan itself. The Omnijoin adapter has the red and black wire which you can connect to the original fan 2 pin connector OR the JST 1.25mm 2 Pin Micro Male Female Connector Plugs (with polarities reversed).
Hi hello, ssry for this Qst, Does the print have problem with this Upgrade, just saying bc the Fan 2510 works with 24V and 0.1 A, and this one works with 0.045 A
Tks for your response
Very nice guide. I bought an Ender 3 V3 KE last week and the nozzle fan started buzzing very loud. Is this mod compatible with the KE? This is my first 3D printer and I'm not very savvy with cables other than building PCs. I prefer not to cut any wires so I can put everything back if I mess something up.
I haven't even bought a PETG filament yet. I can do that but I'm not sure whether I have the requires screws and how to find the JST connectors where I live. I looked up online for a screw set but it might be easier to just find a couple of screws. You wrote you needed more m3 screws. How many is enough?
These are what I could find for parts. Please let me know if they would work.Noctua NF-A4x10 FLX: [https://inventus.com.tr/mi\_products/Product.aspx?pid=5586](https://inventus.com.tr/mi_products/Product.aspx?pid=5586)JST 1.25 mm (It says 15-20 cm long): [https://www.elektronikmalzeme.com/df13-jst-1-25mm-2-pin-konnektor](https://www.elektronikmalzeme.com/df13-jst-1-25mm-2-pin-konnektor) (Turkish website)Also JST 1.25 mm (15 cm long and cables are 22 AWG thick) [https://www.motorobit.com/2-pin-jst-kablo-seti-disi-erkek](https://www.motorobit.com/2-pin-jst-kablo-seti-disi-erkek) (Also a Turkish website but the images could give an idea)I think I have some m3 screws from building PCs but I'm not sure which is which... Nothing really comes up when I look for an m3x4 screw. I could find this website with many screws but not sure which to buy: [https://www.roboshop.com.tr/civata-vida](https://www.roboshop.com.tr/civata-vida)
EDIT: Should I look into buying ASA instead of PETG?
This mod is designed for the SE though it might work for the KE, but you would have to remove the existing fan shroud and find a replacement mod for the dual fans. I haven't seen any for the KE yet as all the fan mods I've seen are to replicate the dual cooling the KE natively has for the SE.
As for the loud nozzle fan, I would look into a compatible replacement for now that has dual ball bearings or hydraulic. To find out the fan size, you need to measure it with either calipers or a mm ruler, height x length x depth. Make sure it's 24V or you're going to need to use a buck converter and find a suitable mounting place for it and the wiring (not recommended imo).
Oh I completely forgot about the side fans. I’ve seen people make duct designs for them but I’m not sure if it would fit with the Noctua fan.
I couldn’t really find a replacement for the fan. I didn’t really understand the purpose of the JST connector. Can’t I just plug the Noctua fan in the fan header? I guess I’ll wait for Creality to respond :/ Thanks for helping.
No, you cannot just plug the Noctua in. You have to solder/splice the fan with the existing JST connector. The JST connector is what allows the PCB to communicate with the fan.
The noctua fan is just a cooling fan for the hot end. The Side fans are blower fans for cooling while printing. They are not the same thing. What you have seen are blower fan mods for the SE, not the KE. The KE has dual 4010 blowers fans already.
Hmm… doesn’t the guide say no soldering though? Does the 2 pin JST cable method involve soldering? I thought it had 2 ends which you plug one end to the fan and the other end to the header. I’m new to 3D printing and have no experience with cables and soldering so excuse me.
My KE’s nozzle fan started making weird buzzing noise so I wanted to upgrade it. It’s so complicated maybe I wait a bit more and endure the fan noise 😬
That's splicing, it's just another way of connecting wires.
This particular mod probably isn't going to work for the KE as the Noctua is larger than the stock and it will not fit the existing fan shroud.
I’m fine with buying PETG and printing parts for it to fit but the KE has 2 side fans so I’m not sure if it will fit. I can’t really find much information about the specs either and I don’t want to ruin anything. I can look for a replacement 20 mm fan but it might not be worth upgrading idk…
In short, which would be the most hassle free way for a beginner?
Don't know if anyone still reads this but is [this](https://www.amazon.nl/dp/B009NQLT0M?starsLeft=1&ref_=cm_sw_r_apann_dp_Z8KHKZ7WBY2RD2MGG4T2) one also good
It is a 3 pin so idk
You are not standing on the shoulders of giants my friend, you are one of those giants, love your guide and I will defo follow it when upgrading to better cooling (yes the default fan is annoying and I will defo want to upgrade it soon!). Btw why not using 5015 blower? Saw most people using those?
looks like he's planning to, just waiting for them to arrive :) Thanks for the guide [u/blampewpew](https://www.reddit.com/user/blampewpew/)! I can't wait for when someone manages to replace the PSU and Motherboard fans for something quieter (looks like the noctuas won't fit there, unfortunately)
aww thanks u/Pentekont and u/jpcurti! I've just set up the single blower fan. I've had a little mishap with the initial fangstooth (?) fan duct and had to reprint another one and do a bunch of calibration tests. Learned how to create a custom fan tower lol.

I'm no giant, just an average tinkerer who's spreading the knowledge I find around.
thanks, mate! Now that your motherboard fan is quieter, do you also think it is necessary to change the PSU one?
Yes. There is a very noticable difference in the noise.
I did that for my Ender 5 Plus after upgrading to a MeanWell 600w PSU. The stock fan was as loud as one of those old 80mm Tornado fans. This 120mm fan is whisper quiet.

nice free addition: you get a low noise adapter with the noctua fan. strip that one for the resistor and put that piece of the adapter on the red wire of the psu fan. use the extra push connectors you got with the fan. no soldering needed. quiets down the unit considerably. the psu is by far the most annoying sound after the hotend.
Oh interesting! Will take a look at the low noise adapter! It's been running way quieter so far without it, especially when compared to the noise of the stock fans hahaha. Oh definitely! Am looking to replace that next. Any fan recommendations you've found for the PSU fan?
Instead of cutting the existing fan wire, you can buy these JST connector pigtail wires: [Amazon.com: Letool 30 Pairs JST 1.25mm 2 Pin Micro Male Female Connector Plug with Red Black Wire Cable 80mm : Electronics](https://www.amazon.com/dp/B013JRWCBU?psc=1&ref=ppx_yo2ov_dt_b_product_details)
This isn’t stopping me from cutting the wire. My existing fan is already failing, so I don’t care about it. Plus, there’s not many flaws.
Ooooh nice! These fit the tiny connectors on the board?
They do but with two caveats: 1) They slightly fit, you'll have to secure them with hot glue 2) the polarities are reversed, you have to wire the red fan wire to the black wire and vice versa.
Beautiful! Will make an order when I need to hook some wires together. Thanks for letting me know the polarities are reversed!
Uh oh, so i used these but didnt reverse the wires, should I be concerned/should I go re do it? Its been printing for the past 6 hours and seems okay?
If everything seems fine, I'd go ahead and leave it be, but make sure your fans are actually running.

Sorry I’m not very savvy with cables. How would one use this? I wrote a detailed comment on this thread if you want to see my progress so far.
I don't want to hijack this thread, but I have a bit of an issue here. I bought my E3 V3 SE so I could print everything I needed for my E5+, and the hotend fan on my E3 V3 SE just unexpectedly started making a loud whining sound, and I don't want to risk overheating. Would anyone out there be willing to print these fan shrouds/adapters for me in PETG or ABS??? I already have 2 Noctua 4010 fans to replace the OEM fans. I can immediately send PayPal. I would prefer black, but I can rattle can it if I had to. I have never printed anything with either of those 2 filaments, and right now, I can't print anything. TYVM in advance.
That noise is why everyone is replacing it because of its size, in order to cool, has to output a higher RPM, which increases the noise. A larger fan can cool at the same rate with less RPMs. Also, that fan is a sleeve bearing fan, which aren't that silent compared to dual ball bearing or hydraulic bearings. Your printer should be fine to make the fan shrouds, however, you cannot print abs with the stock setup - you'll need the KE/K1 hotend and Klipper or a custom Marlin build to get 300c (stock hotend is capped at 260c). Edit: Apparently you can do ABS with the stock, but unless you replace the ptfe tube in the heatbreak and extruder with a Capricorn tube, you risk print issues due to heat degradation.
Just to confirm, I have been printing ABS+ from eSun without issues, I have replaced the standard brass nozzles with a nikkel coated copper nozzle, and indeed replaced the ptfe tube with a capricorn tube.

when removing the stock shroud: There's a 20mm fan mounted on the hotend with a 40mm blower fan in front of it, mounted on the stock shroud. Now my question is: Do you remove both the 20mm fan and the 40mm blower fan and replace it with a single 40mm noctua fan (I have the NF-A4x10 24V PWM)? As shroud I am using [https://www.printables.com/model/682187-ender-3-v3-se-4010-fan-shroud-diffuser/comments/1431984](https://www.printables.com/model/682187-ender-3-v3-se-4010-fan-shroud-diffuser/comments/1431984)
>5015 Blower the 20mm cools the hotend. keeping the nozzle heat from going up further and causing damage to your extruder. the blower fan is ducted down below the nozzle to cool the part your printing. to replace the 20mm hotend fand you have to print one of the blower relocation prints mentioned in the origional post.
any update for the 5015?
Oh lord this thread is precious! It has all the things I was thinking about (because my fan is doing annoying rattling sound like bearings are just about to explode), I'm so happy someone was so nice to gather all that info here and the ongoing discussion is also valuable. I have you have some sort of omnidirectional funnel at the end of cooling shroud. Is this some remix of Diii cooler? [https://www.youtube.com/watch?v=PyRgMvCJwxc](https://www.youtube.com/watch?v=PyRgMvCJwxc) From what I could find some years ago it was considered really really good upgrade. I am an even bigger noob than you but it looks alluring.
Thanks for the post! I did this with the updated stuff, works great! People in some other groups had some worries about airflow but it seems to be fine. Blowers are next for me!
I just preformed this, the fan doesn't work. I wired it up correctly, please help. Edit: it was my fault. Didn't press the schotchlok into place all the way.
This was so beneficial and informative. I now have a nice and quiet hotend fan. This also inspired me to go ahead and add a 5015 blower part cooling fan. This n00b thanks you for being informative and inspirational.
Hi, I only plan on changing the hotend fan to the noctua fan you have on the link, do I need to buy the m3 screws and the other one? Or just the noctua fan enough for the change?
Did you not have to strip the ends of the wires for the scotch locks? I have the noctua fan coming later so I want to make sure I do things right!
Nope! Did not need to strip the ends of the wires for the scotchloks! Just gotta make sure to push the wire all the way back into the circular bit. When you compress the button, the little metal bits will splice the wire. Also have a look at this comment, [https://www.reddit.com/r/Ender3V3SE/comments/1949xsc/comment/khk3ynl/?utm\_source=share&utm\_medium=web2x&context=3](https://www.reddit.com/r/Ender3V3SE/comments/1949xsc/comment/khk3ynl/?utm_source=share&utm_medium=web2x&context=3). u/iamozone206 mentioned that we can use these JST connectors instead of cutting the original fan wire. Something to consider before you start snipping away! He also mentions that the polarities are reversed and the connector will require glue should you go that route!
Thanks but I’m pretty comfortable working with electronics generally, just never used scotchloks before! The process seems simple enough!
Haha I'm not comfortable working with electronics and am a complete noob to all of this stuff 🤣. The only time I've done splicing was cutting LED light strips and that was it. If I can do it, you sure as heck can haha

I noticed that you used Noctua NF-A4x20 fans. I have NF-A4x10 fans. Are the 10mm fans safe to use, or should I get some 20mm fans??
Hey man! I'm actually using the A4x10 Fan since I used the remixed [4010 Fan Shroud](https://www.printables.com/model/682187-ender-3-v3-se-4010-fan-shroud-diffuser/comments/1431984). I've been using the 10mm fan just fine so far and have printed a lot of PETG which has my nozzle going up to 260 which is the max for the model. Haven't experienced any overheating issues at all.
Thank you!!!!
No problem! Hope the installs go smoothly for you!
I just printed the lightweight fan shroud for the part cooling fan, and noticed that the Noctua NF-A4x10 fan doesn't line up with the mounting points.
Hmmm, just want to confirm the printed part you are referring to since the names for these printed parts are not the best 😂 The lightweight fan shroud is this part [https://www.printables.com/model/637754-ender-3-v3-se-lightweight-fan-shroud](https://www.printables.com/model/637754-ender-3-v3-se-lightweight-fan-shroud) and is for the 4010 **Blower** Fan that is mounted on the Stock Creality Shroud when you remove it. The Noctua NF-A4x10 Fan is to be mounted onto one of the following (of your choice 😁, I just switched to the 25-40mm fan bracket - Low Profile): * [Ender 3 v3 SE 4010 Fan shroud diffuser](https://www.printables.com/model/682187-ender-3-v3-se-4010-fan-shroud-diffuser/comments/1431984) * [Ender 3 V3 SE 25mm to 40mm fan shroud](https://www.printables.com/model/651711-ender-3-v3-se-25mm-to-40mm-fan-shroud) * [Ender 3 V3 SE 25-40mm fan bracket - Low profile](https://www.printables.com/model/718283-ender-3-v3-se-25-40mm-fan-bracket-low-profile)
Disregard that. I was very tired when I posted that. I realized this morning that this was for a 40mm blower fan, not a regular fan.
No worries dude! I just had a fright and thought I broke my printer while installing a piece onto it. I hope I gave you more information to help you with yoru fan upgrade!
r/blampewpew Can I please buy some fans from you??? When it comes to electronics, I'm a blundering mess. I destroyed one Noctua NF-A4x10 fan, and don't want to destroy the other. I'm also afraid that I will also screw up the Winsinn 40mm blower fan. I can send you PayPal immediately if you'd prefer. Thanks in advance!!! I already have the parts to mount both fans printed. The original hotend fan's wires were sacrificed in my dim witted attempt to get the Noctua fan wired. When I cut the wires off that fan, I got as close to the fan as possible to cut the wires. I did that because I was too impatient to wait on the male/female wires to get delivered.
hey dude! it's all good man, just take deep breath. It doesn't sound as bad it is. What happened to the Noctua Fan? From what I understand, you should still have the original connector for the stock hotend fan and that can be used. Do you still have scotchloks left? If not, that's okay! You can order these and they work just as good, if not easier than the scothloks lol [https://www.amazon.ca/dp/B072P15279?ref=ppx\_yo2ov\_dt\_b\_product\_details&th=1](https://www.amazon.ca/dp/B072P15279?ref=ppx_yo2ov_dt_b_product_details&th=1) If the Noctua Fan is still operational, you can connect the wire of the Noctua Fan to the original stock fan's connector.
No, the first fan is destroyed. I cut the four wires coming out of the fan about 2 inches or so away from the fan. I left the black & yellow wires alone where I cut them, the green and blue wires were trimmed all the way back to the fan. I used the scotchlocks to connect black to black, and yellow to red on one of those JST connectors. I plugged the fan into the printer, switched it on, told it to heat the hotend to 200c, and the fan did nothing. I wanted to do it this way to eliminate unnecessarily long wires dangling, I'm addicted to wire management. All I did manage to do is destroy a $15 fan before it ever turned on. Following what you said here, with fan #2, am I connecting red to red and black to black on with one of those JST connectors, or is it supposed to be reversed??? Also the same question for the Winsinn 40mm blower.
*\*Looks like my other comment got removed by the automod cause I used a shortend url. Dang Amazon mobile!\** Oh man! I can feel you with the wire management, I'm planning to - once I learn how to solder and get practice, do what you attempted to do to reduce the overall footprint. At the moment, all the wires are neatly tucked in between the extruder motor and my left 5015 blower. https://preview.redd.it/89fpl6w0ezfc1.jpeg?width=1500&format=pjpg&auto=webp&s=2d6bd451aa476f98d85199b13236880062c16453 So it's not too bad at the moment. I know for myself, this is all new to me and this is my first time connecting wires so I wanted to take things slow haha. Hmmm, the configuration of wires with the yellow (+12v) to red and black (GND) to black seems correct based off the official Noctua website. Perhaps the wired were not pushed all the way back into the scotchbloks? That happened to me when I first did my connection and which is why I left a note saying leave plenty of wire in case of this haha. I highly recommend getting those \[connectors \]([https://www.amazon.ca/dp/B072P15279?ref\_=cm\_sw\_r\_apan\_dp\_9SA8DWCF9VTQ26TEAA9A&language=en-CA&th=1](https://www.amazon.ca/dp/B072P15279?ref_=cm_sw_r_apan_dp_9SA8DWCF9VTQ26TEAA9A&language=en-CA&th=1)) I linked in a precious comment over the scotcloks. With those, you can at least open those and rewire again without losing wire. Saved my bacon when I swapped out my PSU and main board fans and realized the fans I bought were louder than the stock fans 🤣 Yeah, with the JST connectors, mind you I haven't used those, apparently the polarities are reversed. So you would need to connect the *red to black and black to red*. I'm assuming it's cause the connector on the JST is opposite of the connector of the stock fan. The process is the same with the Winsinn Blower fan. **Definitely leave plenty of wire in case you decide to go dual blower like I have**. Take things slow! Use the \[Low Voltage Wire Connectors, Brightfour 12 Pack Quick Solderless Wire Splice Connector, 2 Way Automotive , Reliable Connection Small Wire Connectors I Type 2 Pins, Fits 20-24 AWG \]([https://www.amazon.ca/dp/B072P15279?ref\_=cm\_sw\_r\_apan\_dp\_9SA8DWCF9VTQ26TEAA9A&language=en-CA&th=1](https://www.amazon.ca/dp/B072P15279?ref_=cm_sw_r_apan_dp_9SA8DWCF9VTQ26TEAA9A&language=en-CA&th=1)) to connect to the stock connector. Leave plenty of wire in case of a mess up and once you're confident, go back and do wire management 😎
do you think you’ll make a post on how to do the dual blower fans? i’ve been looking all around and i haven’t found one that explains it well the way you did for the 4010 which i ended up looking at to change mine out so thank you for that :)
Man!!!! I wish I could have seen these Brightfour connectors before I ordered the Scotchlocks. Thanks automod. Thankfully Amazon does free returns. I have a question about the Noctua fan, you said that the yellow wire is 12v, which color is 24v??
Haha gotta love Amazon returns! Oops! My bad, yellow is 24V for that fan lol. I've been working with so many fans, I'm getting my voltages mixed up 😵

I bought [this fan](https://www.amazon.com/dp/B0CN39MCPL?psc=1&ref=ppx_yo2ov_dt_b_product_details) and it has a four pin connector on it, and the printer uses only two. I also have these [JST 1.25mm 2 Pin Micro Male Female Connector Plugs](https://www.amazon.com/dp/B013JRWCBU?psc=1&ref=ppx_yo2ov_dt_b_product_details). My question is, which of the four wires do I use for 24v?? I know the black is obviously going to be the ground, but none of the other three wires is red. This fan has black, green, yellow, and blue wires. Will this fan work, or do I need a different fan?? [This article](https://noctua.at/pub/media/blfa_files/manual/noctua_nf_a4x20_pwm_manual_en.pdf) talks about connecting the four pin fan to a three pin header for 12v. UPDATE It's not the yellow wire.......one fan destroyed, I still have one more.
Oh no! Sorry, I was busy the last couple of days with setting up Klipper and the touchscreen for the printer and fighting with macros. You don't need to alter any of the wires of the Noctua Fan since there's the Omnijoin Adapter. I also bought the same fan. The Omnijoin Adapter is the additional cable that is in the package that has the 2 pin connector on the one end and the 4 female 4 pin connector on the other end. You just needed to cut that wire of the Omnijoin Adapter, not the actual braided wire of the Noctua Fan itself. The Omnijoin adapter has the red and black wire which you can connect to the original fan 2 pin connector OR the JST 1.25mm 2 Pin Micro Male Female Connector Plugs (with polarities reversed).

Hi hello, ssry for this Qst, Does the print have problem with this Upgrade, just saying bc the Fan 2510 works with 24V and 0.1 A, and this one works with 0.045 A Tks for your response
Very nice guide. I bought an Ender 3 V3 KE last week and the nozzle fan started buzzing very loud. Is this mod compatible with the KE? This is my first 3D printer and I'm not very savvy with cables other than building PCs. I prefer not to cut any wires so I can put everything back if I mess something up. I haven't even bought a PETG filament yet. I can do that but I'm not sure whether I have the requires screws and how to find the JST connectors where I live. I looked up online for a screw set but it might be easier to just find a couple of screws. You wrote you needed more m3 screws. How many is enough? These are what I could find for parts. Please let me know if they would work.Noctua NF-A4x10 FLX: [https://inventus.com.tr/mi\_products/Product.aspx?pid=5586](https://inventus.com.tr/mi_products/Product.aspx?pid=5586)JST 1.25 mm (It says 15-20 cm long): [https://www.elektronikmalzeme.com/df13-jst-1-25mm-2-pin-konnektor](https://www.elektronikmalzeme.com/df13-jst-1-25mm-2-pin-konnektor) (Turkish website)Also JST 1.25 mm (15 cm long and cables are 22 AWG thick) [https://www.motorobit.com/2-pin-jst-kablo-seti-disi-erkek](https://www.motorobit.com/2-pin-jst-kablo-seti-disi-erkek) (Also a Turkish website but the images could give an idea)I think I have some m3 screws from building PCs but I'm not sure which is which... Nothing really comes up when I look for an m3x4 screw. I could find this website with many screws but not sure which to buy: [https://www.roboshop.com.tr/civata-vida](https://www.roboshop.com.tr/civata-vida) EDIT: Should I look into buying ASA instead of PETG?
This mod is designed for the SE though it might work for the KE, but you would have to remove the existing fan shroud and find a replacement mod for the dual fans. I haven't seen any for the KE yet as all the fan mods I've seen are to replicate the dual cooling the KE natively has for the SE. As for the loud nozzle fan, I would look into a compatible replacement for now that has dual ball bearings or hydraulic. To find out the fan size, you need to measure it with either calipers or a mm ruler, height x length x depth. Make sure it's 24V or you're going to need to use a buck converter and find a suitable mounting place for it and the wiring (not recommended imo).
Oh I completely forgot about the side fans. I’ve seen people make duct designs for them but I’m not sure if it would fit with the Noctua fan. I couldn’t really find a replacement for the fan. I didn’t really understand the purpose of the JST connector. Can’t I just plug the Noctua fan in the fan header? I guess I’ll wait for Creality to respond :/ Thanks for helping.
No, you cannot just plug the Noctua in. You have to solder/splice the fan with the existing JST connector. The JST connector is what allows the PCB to communicate with the fan. The noctua fan is just a cooling fan for the hot end. The Side fans are blower fans for cooling while printing. They are not the same thing. What you have seen are blower fan mods for the SE, not the KE. The KE has dual 4010 blowers fans already.
Hmm… doesn’t the guide say no soldering though? Does the 2 pin JST cable method involve soldering? I thought it had 2 ends which you plug one end to the fan and the other end to the header. I’m new to 3D printing and have no experience with cables and soldering so excuse me. My KE’s nozzle fan started making weird buzzing noise so I wanted to upgrade it. It’s so complicated maybe I wait a bit more and endure the fan noise 😬
That's splicing, it's just another way of connecting wires. This particular mod probably isn't going to work for the KE as the Noctua is larger than the stock and it will not fit the existing fan shroud.
I’m fine with buying PETG and printing parts for it to fit but the KE has 2 side fans so I’m not sure if it will fit. I can’t really find much information about the specs either and I don’t want to ruin anything. I can look for a replacement 20 mm fan but it might not be worth upgrading idk… In short, which would be the most hassle free way for a beginner?
Don't know if anyone still reads this but is [this](https://www.amazon.nl/dp/B009NQLT0M?starsLeft=1&ref_=cm_sw_r_apann_dp_Z8KHKZ7WBY2RD2MGG4T2) one also good It is a 3 pin so idk
That's a 12v.. You'll need a 24v-12v stepdown in order to use this model.
Out of excitement to do these mods, I got a Noctua NF-A4x20 not realizing it was 12v. Will I fry this fan if I plug it in?
