I am running an ASUS P5Q Pro/Q9300/4GB ram/XP Pro/Sapphire 4850 1GB and I have run four different temp monitor programs and I get a huge difference between, what I assume is a general CPU temp and the four CORE temps. Can anyone explain the difference I'm seeing or is there some problem with the readings I'm getting from either side. Which is more correct & what can I do to correct it if this is not normal? If it is normal what do I believe to be true??? Speedfan - CPU=~32C/ COREs 0,1,2,3=~49C ASUS PC Probe - CPU=~32C Real Temp - COREs 0,1,2,3=~49C Core Temp - COREs 0,1,2,3=~49C Within the BIOS it only reports CPU=~22C (this I believe is due to the fact that the cpu fan is at max & no cpu usage at all while in the BIOS setup screen) These temps are only approximate. I would have to double check them if anyone whats specifics. Thanks, any info is much appriciated.
