nice guide, its a pitty that we don't have any hardware stores near my town that sell higher than 600 grit >.<

You need to go to an automotive store for it


they should have up to at least 1500


If not, stop by your local body shop. They will have it

it is and it isnt. with a perfect application of thermal paste a perfectly smooth cpu and base will yield the best performance, however if too much thermal paste is used, not enough pressure is exerted in spreading the paste out, or the paste is spread out over the IHS (finger in bag or credit card technique), and the lack of scratches or other gaps for the paste to fill will cause poorer performance then a standard finish.

In other words, if you know exactly how much thermal paste to use, lap. If not, stay away from the sand paper.

Yes, he is correct.

When lapping a CPU and your HSF... you need VERY little TIM.

As Kenny said, you will do more harm than good if you put to much.

Hey dave remember that liquid silver stuff? I remember it being a mess but that would be godsend for lapped/polished heatsinks wouldnt it?

Rubbing compound, FTW!

For those NOT in the know, here in the UK we have T-Cut, it ROCKS

got that on my opty 185 die

just a quick Q, for "fitted" blocks, like say a full coverage waterblock, would lapping remove too much material for there to be less contect with the gpu die? since u can just tighten down the block more, it will always be the same height due to the shim etc (2900xt for example)

You would just have to be very careful of going too far. I would only lap at 1000grit plus. I don't even think it should be done unless its really bad.

I dont really see why you wouldnt want to go past 1000 grit?

quick question: when lapping a hsf/wb must one also lap the processor?

No, it's not necessary, but it would likely help. But by the same token, it would void your cpu's warranty.

i should get some paper together and prepare for it cuz im re-doing my loop

awsome.... take pictures!
