I'm running an Asus P5AD2-E Premium (LGA775) with a 560 Prescott (3.6Ghz, 1MB L2 cache). I have 2GB of DDR2 Corsair 5400C4PRO. When I POST and go into BIOS' hardware monitor I get temperature readings ranging from 77.5 - 78.5 celcius. This is obviously way high. I go into Windows XP SP1 and the Asus PCPRobe as well as CPUcool report similar temps although when running idle in Windows XP SP1 my temps range from 63 - 69 celcius. When I do anything at all (open a simple app) temp climbs to over 73 celcius and I can't do anything without hassle (instability).
So, I put the machine into S3 standby and when it comes out from Windows standby the temps are reported as around 36 - 40 celcius in PCProbe and CPUCool. And when I run an app (any app or even Prime95 in torture mode) temps don't get above 44 celcius AND the system is stable!
Now, I can't believe something as innocuous as going in and coming out of system standby could alleviate a problem as serious as thermal conditioning which begs the questions - does anyone have any information on this or have a similar situation?
