Hello, I was wondering about the fan on the top of the heatsink for the CPU...I just replaced the AMD one with a thermaltake one I had lying around. My question is should the fan be pulling air out or blowing air on it. My CPU temp is 64/147 degrees when just running idle...shouldn't it be lower? I have 3 fans in my case also...one in the rear just above the video card, one on the side panel and one on the top of the case... Any suggestions or answers would be helpful.
