I got bored this afternoon and made a trip up to Autozone. They had quite a selection of Imperial WetorDry Automotive Sandpaper so I picked up 400/800/1000/1500/2000. 4 Sheets in each package @ 3.99 a package.

Came back home and removed my True120 which didn't have a great finish to begin with, and my Q6600. I used my Glass Top Desk as a base, and used a combination of wet/dry sanding to achieve the best finish "I" could muster up.

Now that I got the techique down, my next go around with a new cpu/heatsink will be much better. But today's session didn't turn out that bad, and I saw a great improvement in temps.

Ambient temps here at home have always been on the hot side (75~79F), and heat has always been a concern for me.

So not very detailed temps, the jist of it is below
Q6600 @ 3.2Ghz with 1.46vcore

before
Idle 49c
Load 69c (tested with Orthos)

after lapping
Idle 42c
Load 53c (tested with Orthos)

Now my idle temps dropped a decent amount, I was mainly impressed with my Load temps!

I have pictures of the finished cpu and heatsink in my sig for those interested. Thanks to lapping the cpu/heatsink I was able to turn down all my fans down to 1200Rpm (chipset is at 1600) and still keep a relatively quiet and cool rig which is what I was going for!

Just wanted to share :-)

That's pretty awesome. How long did it take to do that? Also what did you do to get that result?

There are a few great guides out there (on XS), and well I simply read a few and took what I could from each one to achieve the results. All in all it took me about two hours and was a relatively inexpensive mod.

I've had this CPU since February and from the get go it has been a hot one, I got "unlucky" and got a cpu with a high VID (1.35). I was unwillingly at first to lap the cpu, however after it was completed I was amazed with the temp difference.

I will add that the CPU was the easiest to lap, the heatsink on the other hand proved to be a little stubborn being with heavy and not having having any real good place to get a good grip on it. I mainly wetsanded the heatsink due to this.

I lapped my Q6600 G0 last year and was amazed at the difference in temps. Currently running at stock with a basic cooler master HSF @ 32C idle. The whole process is very easy. Since then I have lapped all my Intel processors, I have been surprised at the uneveness of the intel chips. All of them were either concave or convex. After the first 10min look at the chip, you will see that either the corners sand first or the middle. Congrats Roliath :)

Heh just lapped my q6600 and my temps dropped by 4 degrees! :) It's currently running at 1.5V Vcore and 3400Mhz. Got 280,400,800,1200 and 2000 grit sandpaper all for 2 - definitely worth it! (nana2)

I redone mine too,that Thermalright Ultra 120 Extreme is to heavy ,I just bearly bump my case and it shut down.I took it out and relap it and got a lot better tempertures .I am running my Q6600 at 1.31v at 3240gigs and it runs 32c to 35c and with prime 95 stress test it runs at 53c to 57c.
