I simply sit at the login screen in Windows Vista, and the fans (by the sound of it) rev up to about 6000RPM, and I'm not even doing anything. The little rubber pads inside my Speck case actually get kinda mushy and stick to the bottom of the computer. I tried to remove the case and the problem didn't let up. Ideas? Temp during a game is about 200 degrees F, so that's not good. I end up taking the bottom off and propping the thing up on Legos.
