Core i7 920 rev D0 stepping 5 :)

Yeah, that's another possible point...Or maybe the CPU is concave or corvex and makes a very bad contact with the Heatsink.

Well my last 920 was fine wit this HS...kind wish I kept it.
I put a razor on top of my D0 and I looks fine. HS is making full contact and I even did the True washer trick.

Can a bad board make CPU run hotter?

It may, but very rare if ever. Only thing I could think of is that Intel may have made a bad IHS contact with the core inside, so heat transfer is very bad.
