I have an Antec Full Tower Case. The Case is about 3' tall and about 2' deep. It has dual 4" cooling fans above the power supply in the back, and a single 3" fan in the front. I believe the power supply is sucking air out the back, instead of pulling it in. There is also an Alpha PIII cooler and a 3dfx Video Freezer inside, but I don't think these will afect the air flow too much. My question is, should I set the back fans to pull air in, and the front fan to push it out, or vice versa? Anyone with a similar setup who has some info would be helpful.
