Lapping Guide
Re: Lapping Guide
i think i know why you posted this, but just cleaning it is just that, it doesnt improve the contact surface for better heat transfer, only lapping does(that is what it is for )

Re: Lapping Guide
There is some risk involved yes, but if you are careful/know what you are doing then all will be fine.
I could probably get more from rubbing compound, but the finish that I was able to get with 2500 grit was plenty of a mirror shine for me. Finishing off the lap properly would be the best course of action, but I can't be bothered
Maybe when I go quad penryn core, but not right away. You never know, the CPU might like some time to settle in.

Re: Lapping Guide
I used an extra protection of masking tape on the back side of my E8400 when I lapped mijn a couple of days ago a because, it was or had a dimple in it, and i had to lap the heatsink also, which had a dimple on it also a X-1283 cool temps are the result.

Re: Lapping Guide
you are actually more likely to do damage to it like that, you are very likely to contaminate the pin contacts

Re: Lapping Guide
The black original black pin protector was on the bottom of the cpu before i put the masking take on the chip to add extra protection

Re: Lapping Guide
Great article! I've been lapping CPUs (though I normally wait thru several months of burn-in testing to do so) for years and reaping the benefits of added cooling for great overclocks.
One thing I like to do when lapping is drop a couple drops of dish soap (liquid) onto my moistened sandpaper after it's soaked in a tub of water for a few minutes. This makes it a little easier to slide the heatsink slowly and steadily across the sandpaper. To check my lapping to flatness, I also like to use a piece of *dark* lined (the blue/green lined stuff works too, but can to be too light to really see well) graph or grid paper & check the reflection of it in the CPU surface for distortion.
