12000 Grit, thats awesome where do I get me some? And I can't wait to get my CPU lapped, I really am hoping for more drop. Also once finished it's hard to tell how much paste I should be using, before lapping, in theory at least, there are more imperfections making for more TIM space. After lapping the two surfaces will be near perfect. Also is it needed to washer mod to bring the pressure back up to spec, I must of removed a good half mm of material off the Noctua due to its slight grooved finish. Any suggestions?
