I have the Stacker 810 case with 3 harddrive modules mounted in the front. Each of these has a 120mm fan mounted on the face of it and they are currently blowing inward. There is also an 80mm fan on the top of the case blowing outward, a 120mm fan in the rear blowing outward, and the two 80mm fans in the power supply also blowing outward. I'm trying to cool my video card and motherboard down a bit more so I can overclock. My CPU temps are fine but any help in that area would be appreciated as well. My question is, how should I have these fans for the best air flow or should I have more exhaust fans to keep up with the 120 intake fans? There is a spot for 2 more 80mm fans on the lower rear of the case, would it help to suck hot air down toward that, pull cool air in from the back and forward, or just leave it as a metal plate? Any help would be great. Thanks guys.
