Heat probs reported for Intel E8400s

[alex17 GTX]

Strange senzors on these chips.
With coretemp i have 40/40C in idle and 47/40 in load at stock speed. I seems odd that only one core gets hotter.

And i have a problem with my DFI DARK (965). CPU vCore is set on auto and the VID = 1.125. But the actual vcore is 1.15 and i can not set a lower value. Besides that cpu-z is reading totally wrong (1.232).

I hope only the vcore is higher than is should.
