Ok,well I seem to be having some problems here, and I think its heat issues, but im not sure. anyway,on to the problems. When im gaming (call of duty 2) i start out fine, great fps from my 7900 GT, and then as i play longer, out of no where i start getting huge pc lag, not internet, and at first I thought it was my cideo card heating up, but it wasnt, staying at normal temp's, but then would go away, then it did it one more time and BAM, freeze up and locked down completely. so I had to restart, and its done this before to where it just restarts, and I noticed when it does this it's pretty warm in the room im in and pretty warm under m desk, which lead me to believe it might be my cpu heating up, but im not sure. In my case i have just one big 120mm fan in the back and a normal small size fan on the side of my case, and im not thinking its enough. So do these problems sound like heat? if so, i plan on adding another 120mm fan on the front of the case for some more air flow.
