True!

Start lower, even 600 may be a bit fine for some HSF or IHS surfaces (I don't think that I would start below 400 though). Starting lower will add time, in some cases a considerable amount (1-3 hours). It is worth doing it right the first time, just remember what your after: mirror image and a "glass-like" appearance.

I'm thinking of removing the heatspreader on my X2 3800 AM2, are these removable like the s939 version?

I said to start with 1000 grit and will say it again. He has never done an IHS before, so what if it takes a little while, thats a good thing, at least he wont sand to much off to quickly. It wont take long at 1000 grit, your talking about taking off 1/1000's not 1/8 and 1/4's...Just because I can start off with a file and finish with fine paper doesn't mean I would tell him to do it....

Your point about not removing too much is duly noted - that important. Perhaps a few swipes w/ the 1000. If the lans and grooves are not uniform accross the surface (or fairly close) maybe drop 1 grade of grit.
I say this for I started w/ 1000 and only the corners of my IHS were being taken down. I went down to 600 in order to get it right.

Unsure, never tried them but some claim the AM2s are soldered on and won't come off.

They were arguing on the previous page about how to do it.. It didn't have anything to do with your post..People just forget when you are dealing with first timers it's not a bad thing to start off slow...All the back and forth just gets them confused...

Oh man, do I know what you mean. Bear in mind that I have only lapped 3 CPU's and 3 HSF's (and recently - not a lot of exp.). But the first time (linky from before) I was confused by the varying answers - de-ja-vue

Yup... slooooww

Can you afford the gamble? Voids Warranty. If so, I say "Yes!"
