The only way to get it out from under the heatspreader would be to cut off the heatspreader. That, or submerge it in a solvent which would do even more damage to the TIM.

I don't see how I'm over analyzing anything, I have had two A64s eventually become unsuable with the heatspreader because solvent has gotten underneath it and eaten away at the layer of shin-etsu that connects the die to the IHS.

10c drop from lapping both the heatsink and the processor is not uncommon in the least Thunderer... The IHS (lid) on your proc is really a retarded deisng... lets take this awesome coppy heatsink (good heat transfer) and put a layer of nickle (sucks at heat transfer on top of it)............. Also lapping makes both the proc and HSF smooth. This makes for more even contact, which means more heat is transfered, which means lower temps.

He would've had to have run his PC without lapping, to know the "before" load temps, as the temps after lapping are the "after" and you can't calculate the differece without both numbers

well guess what ? maybe you need to be a bit more careful then and not slop solvent all over everything , the idea is to clean it not soak it

Im gonna lap my TT120 next week when my easypckit arrives. Im pretty sure I can handle the lapping itself but how the hell do you keep your TT120 from sagging downward? almost looks like its drooping a little.
