If you use something like Everest you see your CPU temp as read externally by the motherboard and then you read the internal temp per core basis thats got via the on-die diode.
So all these sites like [H] or anand or whatever, when they show temperatures in OCing and mention it was stable at X degrees and Y clock...what are they referring to? Core (like the hottest of them all) or CPU overall?
Any good site to see what are the "safe" temperature ranges for cores?
