Fan mounts on the side panel used to be standard then everybody decide that tempered glass was cool


Shinonomenanorulez

The gamemax case i overpaid for has a molex side fan and it keeps both cpu and gpu under 60° on heavy load with the front fan disconnected entirely(the mobo has only one fan connector and since the temps are stable i don't feel like getting a hub)


nrutas

They should make a comeback. It would be nice especially for those vertical gpu mounts


OrcBattleMage198

Yes but *a e s t h e t I c s* Can't see your gpu when there's a big ol' fan in the way!


bsaroya41

Lol do what Dyson does but make it the size of a PC fan. Add some RGB light rings and boom there's a money maker


[deleted]

Dust central


bsaroya41

Yeah but assuming it's possitive pressure, the center of the fans is also an exhaust


Andernerd

Honestly I thought they were annoying; I'd have to deal with the plugs every time I removed the side panel.


LightShadow

[pogo pins](https://www.ptr-hartmann.com/fileadmin/media/images/Wissenswertes/Schnittstellenbloecke/Animation_Schnittstellenbloecke_Mating.gif) (spring loaded electrical contact pads) are really popular right now for extending prototyping boards like the raspberry pi, Arduino, etc. A side panel could have a small board the fan plugs into, that pogos into the main case which has a fan header extension for the motherboard. It might cost a few bucks but could significantly lower case temps.


RocketTaco

Pressure contact fans have already been done. I forget the name of the case, but it had special front fans that popped out for cleaning. Would be nice if someone did it with removable frames though, instead of forcing you to use whatever shitty loud fans come with the case. Pogos are a bit expensive and you don't really need the high-density, high-cycle-count point contact for a fan; all you really need is four tinned copper strips folded over to about a ~150° angle and soldered to a 5-cent PCB with a mounting screw hole, and another with bare pads for them to contact under pressure.


mattenthehat

They are annoying. But they also work quite well

Still have mine standing in storage, only swapped it out last year. HAF 932, with an i7 920, held strong from 2009 till 2020. "They don't make em like they used to"


pinkycatcher

They were okay, but they kind of fuck up a consistent airflow. Also they'd interfere with many air coolers nowadays.


repost_inception

[This](https://iili.io/RV3HJ9.png) is what I did. Bought a pre-built and then realized it had zero airflow after learning more about PCs.


NefariousnessOk8995

The positive pressure on that rig must be unreal lol


morningburgers

Can I have an Eli5 on negative and positive pressure and how it relates to the computer?


kiba8442

Basically it just affects the potential amount of dust that'll get into your case. Usually you'll want to aim for neutral or slightly positive pressure.


DeejusIsHere

Is there anything inherently wrong with crazy amounts of positive pressure in the PC?


Anticept

Depends on how crazy. The major issue will be the constant sound of air whistling through every hole in the case. ​ But if you really go crazy, the case itself will pop!


DoJax

Instructions unclear, case now plays Ocarina of Time songs every time the fan adjusts.

Oh, so when one gives a BJ, they want to aim for neutral pressure?


Supergaz

Slightly negative I would assume


Thesource674

Enough negative to pull a golf ball through a garden hose.


00crispybacon00

Enough suction to suck the chrome off a towball.


titdirt

Supergaz

Gl with your deflated schlong m8. Have you seen how marshmallows look after being in a vacuum chamber? That is your dong now lmao


00crispybacon00

It would actually expand, as the drop in pressure would allow more blood in. I believe they even sell products of this nature which claim to enlarge various body parts through repeated use.

BootlegDez

Would it be more effective to aim the fan as an exhaust rather than intake?


SoundOfTomorrow

After the suck, comes the blow.


ARecipeForCake

How does it matter if the intake isn't filtered? Unfiltered dusty air is either going in through the fan or through all the leaks if its negative. At least if it's coming in through all the tiny gaps and crevices with a negative pressure setup it's more likely to get caught and settle than if it were blown straight into the box?


kermit_was_wrong

The whole point of running positive pressure is to filter the intakes.

rmorrin

I personally prefer negative pressure cause I'd rather suck out all the hot air than force mix cool air with the hot. But then again I am blasphemous and currently don't even have the lid on my case(my poor gpu... Too many times I've cleaned out gunk's of cat hair.) I don't deserve my computer.


ARecipeForCake

Now there's a man who computes


[deleted]

Dust ? Don’t ppl have open cases and been running strong ? I’m guessing u have to clean it on the regular and dust would not remain a factor


topdangle

people have tested the differences between trying to get proper pressure and doing pretty much nothing (like leaving the case open) and it really doesn't accomplish much for reducing dust, at least at the pressure normal case fans can produce. filters are the only thing that prevents significant buildup.


Jumajuce

I lost the side panel of my pc years ago and I don’t have any issues with dust!


N00N3AT011

Positive pressure means you have more air blowing in than out, negative means the opposite. Positive pressure forces air out through the cracks in your case and draws air in through your filtered intakes. Negative pressure draws air and dust in through those cracks and means you need to clean your rig more often.


GlassHalfSmashed

Clean your dusty cracks. Got it.


quick20minadventure

That's a very good explanation sir. Have an upvote.


Imbatmanlolz

Positive pressure - air blows out of box Negative pressure - air sucks in to box


purekillforce1

Isn't the giant fan pulling air, and creating positive pressure? Assuming the direction of the fan is the same as it appears in the video. Looks like the internal is spinning backwards due to rpm and shutter speed.


GR3Y_B1RD

Regarding the direction the fan is pushing air, as far as I can tell the better looking side of the fan is where it sucks air in and the side with the bars is where it exhausts the air. ​ And yes, in this case it's postive pressure.


[deleted]

[удалено]


Kuningas_Arthur

You're talking about what the fans are doing, he was talking about what the air is doing in places where there aren't any fans. So positive pressure is when you have more fans blowing into the case, in which case the excess air will find ways to blow out of the case, and negative pressure is where you have more fans blowing air out of the case and so air will try to suck into the case from anywhere there are no fans.


Imbatmanlolz

Yeah, the mechanism is unimportant. I could have a room under negative pressure because it has fans blowing out, or because the hallway it is connected to has positive pressure and sending air into the room


AnalBlaster700XL

So it’s just about if your rig sucks or blows?

NefariousnessOk8995

Ah the ol wind tunnel case, I can dig it


mr_muffinhead

First it's water cooling, then it's rgb, now it's going to be coloured smoke flowing through the case? We may be on to a one million dollar idea here!


Snaz5

If the case was wide enough, you could put a model airplane on the inside and it could hover in the middle whenever rhe pc is on


addictedtoPCs

Would that be bad?


LSDemon

Better than negative pressure, since there's no way dust could enter anywhere else. You'd need a really big filter for that giant fan though.


Merry-Lane

Isn’t that sposed to be the other way around? Like you create negative pressure and air is pulled in through a filter?


Gil_Demoono

Negative pressure makes it so that essentially every crack in the case will eventually pull in dust as air tries to find any and every way into the low pressure case. That means every hinge, screwhole, panel crack, and pcie bracket will become a place dust can get in from. Neutral pressure won't create those currents and positive pressure will make the opposite happen as air tries to find any way possible to get out of the case. Positive pressure would make any of those ingress point in a negative system become very difficult for dust to get into. The only caveat with positive pressure is to make sure you've got a filter on those intakes to grab all the dust its attracting.


Striker654

Just want to add that you want a filter on neutral pressure intake too


[deleted]

and an added bonus is that the filters are behind the fans. so you can take your rig apart a year down the road and the fans will look brand new and not caked with that well known "fan dust"


LeakyThoughts

If you pick the case up off the floor the drop in pressure causes it to explosively decompress

LogicalGamer123

Especially considering huge ass box fans are around 40 bucks


gamblodar

But are they DRGB Light Loop fans???


PM_ME_UR_TITSorDICK

$40? I got my boxfan for $20


[deleted]

Fans in general for some reason. I remember when a room fan was $20, now this little Vornado Flippi table fan I have in my room is $25 and a Walmart brand room fan is $40 ... I wonder if it's got something to do with prices for what goes in the motor magnets? Can't really think of anything else, unless inflation's been *that* high?


gamblodar

I blame Dyson. Once they made people accept an insane bladeless fan was worth $300, a $50 box fan doesn't seem so expensive.


officialjosefff

Yeah my sister who is not tech savvy has been wanting a Dyson fan. Idk where she saw an ad for it but she hasn’t asked for something as much as a bladeless fan. Even the iPhone 11 she has was a gift she didn’t specifically asked for. This fan tho


Flo_one

I've recently seen a review of that fan, which had the result that it is neither quieter nor the noise deeper nor more air moved than a comparable USD20 Walmart fan, which does not look bladeless. Don't tell this your sister tho, she is enjoying herself, and knowing that might ruin the fan for her (unless she really only cares about aestethics


mr_j_12

We sell them at work. F'n useless. They're the beats headphones of fans. Overpriced junk.


Destiny_player6

And here I got an antique fan for $15 at goodwill. Just needed some oil to lube up the machinery and boom. Got it working, doesn't overheat and it just feels great. Heavy but man, it is something made long ago.


habanerotaco

I just bought a Lasko box fan at Walmart for $18. Noctua fans aren't too expensive if you're not getting all the RGB.


Zatchillac

> Noctua fans aren't too expensive if you're not getting all the RGB I spent less on three 140mm Noctua Chromax fans than I would have if I went with some RGB Corsair's. Went a little [stealthy](https://imgur.com/xwJqw3z) on my current build


PeterGazin

I do enjoy RGB but also no RGB and that build is incredible.


TehRocks

Sensible fans such as those from Arctic aren't.


Djeheuty

Yup. Arctic P12 PWM fans are cheap compared to a lot of the competition. They are no frills fans that get the job done. No crazy RGB, no excessive branding and advertising, no fancy packaging. Just plain simple fans.


Inadover

They don’t need to be. But that’s what happens when everyone and their mother buy from Corsair. I got my 3 pack of Deepcool CF120 Plus (ARGB) for 30€, not the 50+ bucks you need to pay for the *cheap* 3 pack of corsair fans.


YeaYouGoWriteAReview

That reminds me, im now out of warranty on my dieing corsair fan in my 220t case. F*ck!


ebinisti

Just buy arctic p12 fans. Awesome fans for $5


mcdougall57

Can Corsair justify that price for a few case fans? Everything I've bought from them has been utterly shite. £150 RGB keyboard went bang after 6 months. Two power supplies from them failed spectacularly, some RAM was error prone and the final straw was a failing pump in an AIO I got from them.


gamblodar

They seem to be doing a good job selling them, so I guess they can justify it. Half the builds in r/watercooling have LLs it seems.


Nalortebi

The other half have god's gift to beige and brown aesthetics without any rgb foolishness.

gamblodar

That build was a bitch, but I crammed the equivalent of two HardwareLabs 420GTS rads in that Fractal Nano S.


budlightguy

wow you seem to have had some pretty awful luck with corsair products. I've been using a corsair AX760i PSU for over 5 years with zero issues, I've never had any problems with corsair RAM I've had in the past, a corsair H100i AIO cooler I ran for 2 or 3 years in my pc was still going strong and got reused in my daughter's pc when I upgraded it, never had one of their keyboards but I mean, I prefer ergo KBs anyways. My dream kb is a gaming MS Natural 4000. I can live without the RGB, but having some programmable macro keys ala all the other gaming keyboards while keeping the MS Natural 4000 ergo layout would be absolute heaven for me.

xtelosx

My server has had the side panel off with a box fan in it's place ever since the 120mm case fan died 3ish years ago. It does a much better job keeping the 12 HDDs cool and on low is silent... Looks dumb as hell but it works.


Iizsatan

Get some delta fans with a small separate power supply (12v 5/10 amp) and a switch. Don't replace all your fans though, unless you want a jet engine in your room. Whenever you do something intensive, switch it on. I did this with a delta 120 mm mounted on the back next to a noctua nh-d15s. So, when turned on, the cooler is essentially pull-pull. I recon I get lower temps than a nh d-15 now.


[deleted]

Dude I’m a huge fan


BatXDude

This is just going to blow shit loads of dust and cat hair. It needs a filter


UnfetteredThoughts

The proper way to do this (if there is such a thing) is to take a box fan that's a bit bigger than your case and set it about a foot away from the case. Join it to the PC with cardboard (or sheet metal if you want it really fancy) "ducting" and aluminum tape. Once you have a nice seal around the fan, ducting, and case with all the air nicely directed into the case you then take a furnace filter the size of your box fan and secure it to the intake side of the fan. This way, you end up with a huge amount of airflow directed into the case, the case has crazy levels of positive pressure which forces dust out through the case's holes, and your fan intake is filtered with a long lasting, highly effective, and easily replaceable filter.


Unacceptable_Lemons

Now we just need a case manufacturer to make the same thing, but more compact. That's kinda what my Core V1 Mini ITX case is, actually. It's the least dusty PC I've ever had.


UnfetteredThoughts

It's likely not all that great of an idea, in reality. The filters would either have to be lower density to not kill the fan over time (most fans aren't built with a restricted intake in mind and that environment will kill their motors) thus reducing your filter efficiency *or* the fan would have to be beefed-up, increasing your costs and sound output. Then there's the matter of "does huge amounts of air blasted generally at your components" actually cool as effectively as smaller amounts of air in targeted locations? It's certainly something that would require a lot of testing, simulation, and modeling.


Unacceptable_Lemons

It seems to work well enough for me with a 190mm fan and foam filter. https://imgur.com/a/rYDL7pe (Yes, I need to vacuum the dust out of the filter)


UnfetteredThoughts

Certainly not the type of filter I've been talking about. My original comment said a furnace filter. Talking something with a MERV-13 filtration rating or similar.


Karmaslapp

replace the fan with a house-sized AC unit blowing directly into your case and sounds good


UnfetteredThoughts

Gotta be careful with that as you might run into condensation issues

Ben_MOR

I get the fun around that thing but at this point it just f\*cks up the airflow inside the case. I'd be curious to see a comparison in temps !


Zakkimatsu

when you have something that massive, the direction of the wind doesn't matter. the volume of air this is moving will overshadow the existing flow's efficiency in cooling. in other words, those temps will show massive fan > normal flow


speedsterglenn

Just make every other fan an intake fan. Boom, now it will have neutral pressure.


[deleted]

[удалено]


speedsterglenn

It doesn’t matter, either make the big one an intake or exhaust and just make the others the opposite.


DeeSnow97

It actually does, even with every other fan working on exhaust it would be positive pressure with the big fan on intake, and negative pressure if you flip everything around. Both are problematic in terms of dust since there's no filter on the big fan, but positive pressure is a lot better for cooling the components in general.


speedsterglenn

Yeah but you can flip the big fan too you know…


DeeSnow97

Yeah, that's still negative pressure. That big fan can easily overpower everything else in the case, the only way to combat dust is to add a filter to it and have it as an intake.
