Negative or positive pressure? Does it matter?

[lexluthermiester]

If doesn't makes sense if you don't own a Corsair 1000D, if you do then things are different.

Why?

Exactly.

Why?

Negative or positive pressure? Does it matter?

@claes I have a question for you. Let's say i have 3 top fans exhaust ( push) and then i add another 3 and make it 6 push-pull, are those top fans still counted as 3 exhaust or 6 exhaust?

Hi,
Should say not easily removable/ reinstall

 

[freeagent]

That’s pretty neat.. I have never seen fans that can slide out on a drawer type system.. sweet!

Betcha can’t stand on it though..

 

[Komshija]

Positive pressure should be better but the dust will anyway get inside, regardless if positive or negative pressure.

Hi,
Can be more of a pain seeing you'd usually have to disconnect all the fans before pulling the trays out.

maybe some fan manufacturer needs to make fans with pins connections, the leads stay connected, fans can be removed to clean or change without disturbing the wiring. I would find it very useful

not sure if it was the same case but I recall a jayztwocents video where he had a case with such a feature. it also was highlighting some new fans from someone I forget....but their fans could be daisy chained rather than each fan needing to go directly to a header or to a splitter cable going to said header(s). the point being if all the fans are daisy chained for their power and RGB then you only would have to unplug the one cable going to the header and then slide them all out in one swoop. So there is some good value you there, but need to invest in the right type of fans to make the best use of it in my opinion

Hi,
Yeah I use a controller for the majority of fans
I give the mother board two fans a cpu and cpu optional and that's it.

It's a lot more common on larger systems made for AIOs and/or custom water

My older fractal R6 has similar at the top, although its screwed in and lifts up, vs sliding iirc

some already kinda do this, iirc most of the Chromax fans have their leads terminate very close to the fan (like half an inch of length), so you need to use the included extension to get anywhere close to the board. Disconnect the extension and you can remove the fan without disturbing anything else.

All the more reason to worry about dust.

Early PCs had the power supply blow into the case; modern PCs have it blow out.

I was wondering about a sealed PC case with fans blowing air around internally and the case itself a giant heatsink.

Hi you mean 2005

 

[Ibizadr]

I shared some videos in case someone is new to the topic and wants to know what's going on. What's so lol about that?


That's good advice, but again...

Everyone: Dust is not my issue! I want to make my PC as cool and quiet as possible. I want to know what setup would be best especially for GPU thermals. That's it. Please stop telling me about dust. Thank you.

Put your aio on front with a push configuration use your 2 fans on top as exhaust test and tell us if you got improvement

 

[freeagent]

I would just keep the tops as intake too. Keeps the ram and vrm nice and cool. Chances are your exhaust isn't good enough to get all that hot GPU and system air out quickly, so might as well get as much cool air in as you can. As long as you have vents and a fan at the back you should be ok.

I've tried - it's not good (at least with my config). The GPU sucks in hot air exhausted by the rad, no matter how hard the top fans work.

No fan mount on the back of my case unfortunately, so I need the top exhaust if I don't want all the hot air to be trapped inside.

Otherwise, I could do a top intake / front exhaust config, but that would work against the GPU fans (and against convection).

 

[claes]

Not guaranteeing results, but if you have all fans as intake the hot air will be pushed out of the back by force.

An easy way to shave a few degrees off of GPU temperatures is to remove the PCI brackets.

I've got these vented brackets, but I guess removing them might improve things a bit further:

I'm sure using all fans as intake would create some pressure to push hot air out of the case, I'm just not sure about 1. GPU temps, as GPU coolers are designed to exhaust hot air into the case, 2. potential hot spots, as exhaust airflow is not directed anywhere. I guess some testing might prove interesting.

A lot of GPU Coolers are actually designed with the idea of positive case pressure, and vent out the integrated slot covers
('But that works for negative, too!' says the one person who has to argue... yeah. but you dont see a dust filter there do you? its meant for exhaust)

Hm, you've got a point... except that Gigabyte card that you posted has its cooling fins arranged parallel with the back panel, directing airflow right into your case - same as my EVGA 2070.
