This website has a lapping service for $16 when you buy the Thermalright Ultra-120 Extreme. Wanted to know, is it worth it to lap in the first place? I'm getting a Q6600 G0, Arctic Silver 5, and want to try and overclock to about 3.5ghz. Haven't done too much overclocking myself and never lapped so not sure how I would do on my own. The other thing is I'm not sure how good of a job they will do and lapping voids the warranty. So is worth it for a heavy overclock?
Lapping - Get the best performance from your heatsink with our Lapping option. We will lap the base giving it a nice flat and smooth finish. This option will Void the warranty of the heatsink making this product non-returnable once you have purchased this option. Lapped base is shown in picture to right. We start with a 220 grid and finish with a 1000 grit. Our goal is a flat smooth surface (not mirror finish).
