specs that matter for this:
Evga - 680i SLI A1
Intel E8400

issue: core 0 always reads the same thing while core 1 temp will fluctuate...no matter what program i use core 0 will always stay at its temp (ex: 41) while 1 will go up and down as used (ex: 42-53)

i will run prime on both cores...copy a DVD do anything and 0 seems to stay maybe moving a degree up while 1 will go up maybe 10 degrees...

everest/core temp, etc... all do this....

so..what's the issue? any guesses...is the temp monitor just busted on core 0...is it the mobo reading it wrong...do the programs just suck? any ideas?

and another question: in everest theres a CPU Temp that reads one thing...and then both cores are hotter than that....what is that temp exactly?

Maybe your problem is related to this:

Yeah more then likely i have seen alot of people report high temps possible inaccrute.

The 45nm chips, including the QX9650, have some thermal sensor issues.

At stock speed, 3 of my cores are idling at 30C with 1 idling at 20C. At load or when OC'ed, the temp spread betweentthe cores narrows. I searched the net and turns this issue is pretty common:

That CPU temp is showing the Tcase temperature which is measured at the center of the IHS, and that is why it's lower than the core temps (Tjunction temps) that are taken directly from the thermal diode sensors on the cores. Tcase is the temp that Intel uses in their thermal guide.

contacted EVGA...they said it was a BIOS issue and they are working on it for a future update...
