Basically I was playing a game (Portal!) and the PC started beeping. I thought it was my HD (which according to speedfan was at 50-52 but thats another issue), but then I realized i had enabled the temp monitoring in the bios.
My cpu says its cool at 30C (beep at 75)
the system says its at 43C Beeps at 55
and the PWM - 52C beeps at 90
I assume its the system that is overheating. I was wondering how I might be able to improve the cooling for the system. I have a few case fans (3, 2 back 1 front) already.
