Mr. Max,
I would go higher than 600 grit. It can readily be found at any auto parts store. I went 2000 grit.
theres no extra performance when you go higher, it actually made a slight decrease in performance due to the grooves being too small ... lol dont believe theres actually a thread somewhere in this forum .
i personally went to 2k but then resanded down to 1200.

"The grooves being too small"? What is the logic in that? The idea is to get as thin a layer of thermal compound as possible between the heat sink base and the cpu face since even the best thermal paste provides resistance to heat transfer - and still get complete coverage and contact. Any size grooves add to the thickness of that layer and the deeper the grooves the thicker the layer of thermal pasted needed to fill them.
if you can, post pics of your lapping
AHA! Found it heres the link definitive proof that anything over 6-800 is a waste of time

I think your warranty is void anyway, by using an aftermarket cooler. I could be wrong. I would at least check the flatness of the CPU IHS with a razor blade.how long should i sand for?
how will i know when its ready?
ps im not lapping cpu as i dont want to void warranty im just lapping the heatsink
