if lapping had any benefits i think the cpu manufacturers would do it.

It does but then printing on the CPU would be a b*tch and it only counts if the HSF is lapped too and on and on... Too inconvenient for them.

Lapping has been proven to lower temps.

Hmm... my i7 920 D0's at 3.8 w/ 1.20625.

Anyone have any statistical reference to the legitimacy of lapping? As an engineer, I'm hard pressed to believe in its benefit.

But, then again, we did make it to the moon on fortran...
