Cooler master Sniper case with GTX 780 ACX?

darude908 · Aug 8, 2013

I'm starting my new build soon, but I am having a bit of a dilemma. I am getting a cooler master sniper case (http://www.newegg.com/Product/Product.aspx?Item=N82E16811119194) and I'm definitely getting the GTX 780 ACX to match. Now There are 1 200mm fan on top, 1 in the front, and apparently 1 on the side panel. 1 120mm in the back.

However I found out that there's a vent at the bottom right next to the PSU that can support a 120mm fan. Now the GTX 780 ACX blows air downward inside the case as opposed to the regular GTX where it blows hot air through the exhaust outside the case.

Now my questions are: since the GTX780 ACX blows hot air directly above and onto the power supply intake, will that cause problems? And also should I set up the 120mm fan on the bottom of the case to expel air or take in air or leave it empty? The case does have air filters but since the vent is at the bottom, if I set it up to take in air or leave it empty, it might cause dust build up inside the case.

So thanks in advance!

Your case, same as mine, will work really well with the 780ACX. That video card does NOT blow air down onto anything: The fans suck air in, and it is dissipated within the case and out the back. The PSU should be mounted with the fan DOWN to suck air in from the bottom of the case (there is an inlet under the PSU mount) and it will exhaust its air out the back.
With the rear 120 and top 200 sucking hot air out, the side and front pushing cool air in, the cooling works out really well.
I ran two GTX460's with a similar cooling arrangement as the 780 ACX, and now a couple 660's; nothing gets to warm.

One of the beautiful things about the Sniper, is you can crank-up the case fans when you game or work on heat producing projects, and turn em down when you are surfing the web.

I would leave the rear 120mm fan where it is. If you want more air intake buy another 120 and mount it on the bottom as an intake, NOT exhaust - remember, hot air rises; you can't suck it out the bottom.
Regarding dust: INEVITABLE. Dust will get into your case no matter what you do, so just plan on cleaning it out every couple months.
I think you are overthinking this; wait til you get it all set up and see what your temperatures are.

Awesome, thank you for the detailed explanation. I was worried about the dust simply because where my tower will sit can build up dust really fast thus I'm worried. Also you mentioned to mount the PSU fan side down. Won't it collect dust that way? There is an air filter down below right? And how long do you clean out the air filter on the bottom?

Just to reiterate, you can't avoid dust. When you clean out the interior every month or two, use canned air to blow out the PSU: You say it's really dusty where you live; then clean the PC every three weeks. If it's that dusty, your filters would probably be clogged by then anyway and you wouldn't have any air flow. You WANT your PSU to suck cool air in from under the case to keep it cool.
There is no filter for the PSU, and I wouldn't worry about it. Last time I cleaned my PC, around the beginning of June, I really blew out the PSU,and I never saw ANYthing come out of it. If you must have a filter, get some pantyhose and cut it to size of the inlet and tape it on; pretty good filter,actually.
