Basically you need to get some fine grit sand paper at pep boys, 600 to a 1000 grit. It involves taping the sandpaper to your desk, starting out at a low fine grit and working your way up a higher grit. You'd rotate the processor after each set. I think I went up to 800 grit before.

Youtube has videos of this.

Oh and doing this is a complete waste of time IMO. Better off buying a corsair h50/h70 or antec kuhler 620/920 then wasting time doing this junk.

Cant comment on the results of lapping, but it seems like a good project. I would like to do it at some point to my 955 biggrin.gif. Anyway, here is a guide I found a while ago:

Hope it helps! thumb.gif

i havent lapped my cpu as it is still under warranty but i lapped my corsair h50 with 400/600/1500 sandpaper to a mirror finish (dont ask me why i used 1500 they didnt have anything between 600-1500 *napa auto parts*) but anyways, i got ~ a 5c max load drop in temps. hottest core before was 84-85c max and now its 79-80c max so lapping DOES help. I dont have any experience on the cpu tho so try it out and see! u have nothing to lose!

You want to make sure your surface is flat, i used a mirror and taped the sandpaper to it using painters tape. You also don't want to push down on the CPU this will cause the surface to be lop sided. let the wait of the CPU do the job.

TJ Harlow did a video a few years ago on how to do lapping the proper way. Ill link it below.

Get some cheap/dead CPU first and train on it.

The benefit for the 1366 chips was almost non-existent.

Some people even had worse temps after lapping. The socket puts lots of stress in the middle of the sides of the chip and that slightly bends the chip in the socket on some mobos.

You'd be better off selling your board and chip and upgrading to either 1155 or 2011, the devaluation of your processor from lapping isn't worth the performance gain you may or may not get back.

One thing you can do is take the heatspread off. It will yield at least 5 degrees under load.

I have done that with my i7-920 and i7-960. If you do it right, it's quite easy.
