Wet 400 to 2000, moving in figure-eights. Koala oil if possible. Don't lap too much, and lap on an even surface, such as a mirror. The cost of lapping wrongly could be a burnt out CPU, or just a useless hunk of copper.

Oh yea, and you can mark an X with a marker on the surface you're sanding. Once it's gone, move to the next grit.

Hrmm? AS3 won't help... er, well I don't understand what you're asking.

Yeah, it's a lot more work than you'd think. Hopefully 400 grit was an improvement for the HSF!

2000 grit is a mirror finish.

If AS3 worked that well, there would be no need for lapping now would there? :p You're probably better off than you were before, but the smaller the grit the better.

I always use AS3 too. I just apply a small blob in the middle, then spread it evenly and as thinly as possible using e.g. the edge of an old credit card ;)

a put a paper thin layer or AS3 on the CPU and i put a blob on the HS... put a glove, rub the AS3 the wipe almost every thig with a card.. so only the tiny holes are with AS3

i lowered my temps by 4 degrees by using less as3 than i thought i needed. too much is too much! (thanx fara!:) )

No number, no 'grit' :p You won't be lapping anything with that :D

2000 feels pretty smooth, like a wall with a textured finish, but there's a definite scrape in it.
