Lapping Warning!

Prolimatech does not condone any type of lapping done to the CPU or to heatsink base. Every Prolimatech's heatsink base is designed on a pin-point scale of how the base is to be flat and/or curved where it's needed to be. We have programed our machines to machine the surface in a very calculated way. Any after-manufacture lapping or modding done to the base will alter the design, hence negating its performance factor as well as its warranty.

Canned disclaimer. I have seen real world benefits to lapping a IHS and a cheap air cooler. Prolimatech might have higher standards, therefore not a great idea to lap their products if their products are delivered the way they are designed. But lapping would not be a "thing" around these forums if people had not seen a benefit, just like delidding would not be a "thing" if people did not see a real benefit.

Yeah, I suppose it matters on the cooler used. I have a Hyper T4 here that I plan to lap carefully! (2k Grit straight up)

Yeah, I guess it depends. My waterblock that I have is pretty decent so I would say that it is made like it for a reason just like the Prolimatech stuff is, I ended up getting some Brasso (Man the fumes are crazy!) but I haven't had time to use it yet. I only opened it to see what it was like and almost feinted...

The reason behind their warning is that the heat sink is slightly curved to match the CPU.....lapping flattens that curve and decreases contact.

Just wanted to say that I used emery cloth when I did my lap. Couldn't remember the name for the longest time.
