hmmm, I just read few reports of other people, they all have their cpu core around 50 degrees on load.
I quote: "my is 30c no load and 38c load with bios. With core temp is it is 44c idle and 51c load."
hopefully i'll get a E6300 by end of the month too
update: check again the greese term you put.. check you connected everything together right, and then the degrees should be decreased.
