How does one go by doing it? Are there any experts here?

Nevermind...I found a site that has a guide.

Postcount +2 :D

Anyways...is there anyone that has done it here? What is the performance value of doing it?

No performance gain, it's simply to ensure there is a uniform even surface for the CPU to mate to the heatsink. Just get some decent thermal compound like AS5 and don't worry about it.

lies. some people get 10c cooler load temps after lapping a conroe.

Actually I think i may have to help a friend do this... his conroe idles at 60+.

The HSf was pretty scratched when i took it off... not sure about the CPU.

DOC--head on over to xtremesystems.org. This is pretty much standard procedure over there.

I haven't done this yet, mainly because I don't want to void the warranty on my proc, which it does.

Explain how a drop in load temperature equates to a performance gain, or rather how the temperature of the processor (if inside operating ranges) is directly proportional to performance.

I find it hard to believe that lapping a CPU with the potential for damage exceeds any possible performance benefit versus using quality thermal paste (not the zinc-oxide crap) with a quality heat-sink.

Talk to JAKUP!

He even has a topic about it.

You won't see a "performance gain" per se, unless your looking for slightly cooler temps in order to overclock. I've gotten good results lapping the heatsinks on several items before, usually to 1500 grit. With AS5 you will notice a drop in temps if done properly.

I did this one :D it took a couple hours, dropped the temps 2c to 5c (lee63)

That's some patience and a steady hand. No wonder your rig looks so good. :thumbsup:

I lapped my Celeron D to practice on to 2000 grit.

Here is a pic of my zalman 9500 I lapped.

what are you using to lap on? Im using a sheet of glass.. (that sounded so wrong)

use water when you lap the heatsink, it helps it slide and it kinda sticks to the paper so it doesnt jump around. :D

I heard that also, but I never tried it. Water works perfectly and you can just rinse off your sand paper when you need to.

Here is a link to a tutorial I found while back. Pretty good tutorial on lapping.
