Average or hot?
Got the desktop working recently, but I'm a tad concerned, the CPU at idle sits in the 29-32C range and goes up to about 40C when I'm playing Microsoft Train Simulator with Folding@Home and other apps in the background. The CPU is at stock speeds and Rambo says his maxes at 45C and his is at 3.03GHz.
Do I need a case fan to help get the air circulating in the tower box?
What's your complete run-down of system components?
Do you have more voltage going through your proc than his?
~40C isn't too much to worry about.
