NOTE: If you lap your CPU's IHS you will void the warranty.
Just something to think about first.

Actually most of the time the cpu IHS is what is concave very badly. You will get more of a temp drop by lapping the cpu then anything else in most cases.

Very true, I noticed a bigger drop in temps after lapping my cpu AND heatsink.
As long as you are careful and don't crazy then you have nothing to worry about.

Yes. Keep an eye out on the "For Sale" section.
Also ebay sometimes will have Sellers that are offering up some lapped CPU's

That looks like they have lapped the actual cores, lol.

Not from the factory. You'd have to buy it off of a person. The same problems exist on them, though: You will have no warrantee. The positive thing is that someone has already done the "scary" part and sanded down the processor for you.
I'd keep an eye on the for sale items in this forum.

It looks like they took a belt sander to that CPU. I'd hate to see how long it would take to get it down to the cores by hand unless you use 100 grit paper or something.
Oh and I like to use 90% isopropyl instead of water, especially if there was TIM applied to the chip before. Plus it dries quicker.

Hey guys that is my cpu that I lapped like that. It took a couple of days lol. I lapped it going off of what some others had done and basically lapped the IHS till it got to the silver solder tim they use on the inside. Lapped that off till I got to the cores.
The cores arent perfectly flat either, you can take a very small amount off the top of the cores and not effect the chips at all. When I say a small amount I mean a very small amount.
The edge that is left around the peremiter is nice to help keep your heatsinc level when you put it on. You still need to remove the top portion of your retention bracket on your mobo socket.
