I am building a new system using an old Gateway case. I am putting case fans on both the front and the back of my case. I am thinking of putting one as an intake to blow air in, and the other one as an exhaust to blow air out. Is this a good set up? Or should I put them both as exhaust? Im going to have to modify my case slightly in the front for the 80mm fan I ordered, I already have a case fan in the back. This is my first build and I was just curious what ya think of a fan set as an intake? The only problem I can think of is it may blow dirt/dust etc into my case. Does anyone run a fan setup like this? Thanks!! P.S I already have a HD fan, my Graphics card has a fan on it, and I have a Pci slot fan, and a "case" fan in the back of my case, my new AMD Cpu I ordered comes with a heatsink fan. But it sounds like a good idea to have an intake fan? I plan on overclocking slightly when my new mobo/cpu gets here!!
