Right as I said. I recommend wet lapping, though. I did "dry-lapping" myself, and the sandpaper pretty much died instantly.

What solution did you use for the 'wet' part?

Water! lol<br><br>
Wet sanding will help the sand paper last longer, and help the process go a bit quicker.just be sure to rinse and wipe clean the surface and everything between grits, so the last lower grit doesnt wear out the new new finer grit.<br><br>
When all done with the lapping, you could just take some polish to the surface to make it truely a mirro finish, but this does nothing but cometically make it look nice. I used a little barasso on my IHS when i was done lapping it.

I've heard of using acetone or nail polish remover as well. Just a matter of preference.

Yes go wet.I put on top of a piece of plexiglass and put tape around and put a little bit of water on each pass you can go up or down or side to side.With the big t is easy go up and down.

That wouldnt be too smart! I would think the acetone can damage the silicone finish on computer components... Not to metion the fumes emitted from it whil lapping! You would probably pass out from all of it. Using one of those will have no bennifit for lapping than water would.<br><br><br>
Also, i forgot to mention, when lapping, move the IHS or heatink in a circular, or figure 8 pattern. This will insure an even, uniform wearing down of the surface. Many people tend to think you lapp just to make it smooth and shiny. This is a common misconception. Lapping is done to insure that the surface is flat. Perfectly flat. Most heatsinks will actually have a concave surface, meaning that the center of the surface is lower than the outsides, sorta like the center has a dent in it. Well if you sand it flat and touch it to another flat surface, it provedes much more contact surface, witch results in better heat transfer.

Well in essence, wet lapping can be done with anything! Why not use wine, or pepsi? Or how about maple syrup?!!! lol<br><br>
The point of using a liquid, is so all this microscopic particulate from sanding, (the material being sanded, and the sand paper its self), become suspended in it, so that fresh new sand from the paper is touching the surface. This is similar to lubrication in a way. I suggest using water, its inert, safe for use around computers, its not a solvent, and best of all is very easy to clean up... Oil could be a little difficult to clean, and the whole acetone idea is just scary since its a strong solvent.

You also want to do it in 8's, especially because when you're lapping it, you will have the übersmall scratches from lapping one way when NOT doing the 8's, and having the scratches going all over with 8's, which you want more than just letting them point in one direction.

There is no need to start at 180 or 220 if you don't need to remove material. If you are just trying to get it flat you could start at 600 or 800 (when lapping the HS that is).

I always use waterproof sandpaper. I usually just take a wet cloth and wipe it.
