Hi guys, I just moved my computer into a really tight spot. I didn't have much choice. =/ I realized it's running a lot hotter than before, especially my graphic card. So i just ordered 3 more fans for my case. All the fans are 120mm. I would like to know how should i place them to get the maximum air flow.
From what I've found, always have your intakes near the bottom front of the case and the exhausts at the top/rear of the case.
Exceptions are a fan on the side of the case should likely be blowing into the case onto the graphics card/processor.
The main things are intake on bottom and exhaust at the top. Other than that should only make a 2-3c difference no matter how you place the others.
Get two of those fans on the top of your case for exhaust and i guess the other one as another side intake or on the bottom as intake if your psu allows. The problem you're having is your gpu is a non-reference design and is exhausting heat in your case.
