Awesome! Thanks man.. I will bring the 200grit back out.. hehe

200 is pretty rough. Don't want to cut so deep that it takes you years to smooth back out with 600.

Shouldn't hurt though if you've got the time to clean it up after flattening it out.

Good luck.

it needs to be rough to quickly remove the nickel. then the switch to a higher grit to facilitate the flattening and then very high grit for polishing/evening out. Works like a charm

I have 220, 400, and 600 would that do it? or do i really need the other sandpaper in the K's?

Many folks have tested with a 600 grit finish and found temps to be minutely better even than the mirror finish. It's an old argument.

Bottom line ... once flat, finishing the surface with a good smooth 600grit finish is just fine.

What sort of surface are you setting your processor on while you do this?

003

A small mirror works great, they are totally flat.

A question though. My E6750 also unfortunately has the non flat IHS. If you lap it to be totally flat, wont that make the CPU "shorter" and less pressure is applied to it by the heatsink? Is there a way to make sure the same or more pressure gets applied to the cpu after it is lapped?

thriller

interesting...any answers? i to ponder on this for many hours a day

Theoretically it would, however if what's left of the IHS is still above the bracket holding the processor in place, then it should not matter.
