I have an antec 1200 with the gtx295. AS you know this card runs hottttt. I was wondering how much of a difference i would get if i put a 120mm fan in the side bracket on the pannel of the case. Is it significat enough to warrent me buying one and should I have it blowing in air or sucking it out?
Side case fans generaly blow IN, or if they don't they should.
A fan blowing in on your graphics card will not hurt, and 120mm fans are cheap.
Fill your case up with fans if you want, as long as you can stand the noise.
Ideally, the front fans blow IN across your hard drives, the side fans blow IN
onto your board and peripherals, any back fans blow hot air OUT, as well as
any top fans, which would blow OUT also. That's the ideal config I believe.
