Here is CPU shot of "F" E6600 that is relatively rare.

And I run 32M pi with winter-advantaged air-cooling.

To my impression, "F" E6600 might be much low temp in action than "B" E6600. But, this is just a random sample. Don't be conclusive. I didn't modded Vcore, but more voltage seems to be set. I'm waiting for DFI 965X board for more perfomance on this CPU. :toast:
