A short little guide on Lapping the CPU IHS
 

Lapping an IHS on a CPU is not as hard as most think. It does not require hours of work, and there is none of this, 'You have to do this way, and only this way for perfect results.' Contrary to popular belief lapping the IHS can be done in a matter of minutes and still get a seriously high polish out of it.

Lapping the IHS any good?

Some batches of IHS are really poor and others are better.

Using that high grid is a waste of time and just for the show (proven over and over again that super polished surfaces help almost nothing in reducing temps...

I always use tape on the edges and the Intel protective cover at the back...

I find it funny that they not even mention to lap CPU's when they are concave or convex...(or just a tip for the readers on how to check the flatness of their IHS) A good IHS will hardly benefit from a lap job...

It would have been nice to include temp differences too...

And last moot point, don't use the Swiftech GTZ with the stock mounting on a lapped CPU ( as the pressure has been preset by Swiftech itself...)
