B3 Q6600 core temp differences

[mDust]

It could also be IHS deformation. Lapping would reduce those temps, and might pull them in line. For proof, let me link you an article that shows my old Q6600's TIM footprint...

As you could see, the IHS was BOTH convex and concave. Not too healthy...

Yeah, that's what I thought, so I lapped both the heatsink and processor. It brought the temps down, but the gap remained. As it turned out, my IHS was concave with a convex bump in the middle as well. I had to sand it down to the copper to flatten it out...it was pretty bad.

I think it could be that the HS is not seated properly. I'm not sure about the B3 stepping, but the G0 IHS is just a fraction of a mm shorter than older 775 chips (read my old D820)- meaning the CPU retaining bracket may interfere with the HS properly contacting the IHS.
