Actually, unless you're an oaf, you shouldn't run into any problems unless you manage to drop it directly on the die, or crack the die while installing the cooler.

This is actually the best argument for sanding down to the die rather than removing the IHS altogether (which is a lot more risky).

I lapped my heatsink, it was slightly convex and holding a razor to CPU IHS that was very flat. 2-3C difference, not much of a big deal. If temps are really a concern I'd go WC.

Well, the most ridiculous point I've heard against it is "You'll void your warranty." If you've overclocked it you've already done that. What are you going to do, lap for a cpu you intend to run at stock?

I have a thick mirror that I use for a flat surface and I go in sequence from 220, 400. 600. 1200, 2000, and then newspaper to get a flat mirror finish on all cpus and heatsinks. This allows extremely thin films of TP and always results in lower temps. If your temps didn;t go down a minimum of 15% you didn't do it right.

Makes me think of something. After lapping your cooler and cpu, is thermal paste really necessary? Doesn't lapping eliminate the primary purpose of paste?

You're still going to have microscopic imperfections, even after lapping. So SOME thermal grease is still necessary.

I haven't lapped my Athlon....yet. I did lap my old X2 Manny though. My Opteron ran cool enough I never bothered. My other Opteron, I de-lidded (not the same as lapping, but counts ).
