Lapped cpu! Lapped heatsink?

post #1 of 16
Thread Starter 
I have decided that tonight I will try to lap my cpu to bring down the temps. Would you guys also suggest lapping my Zalman 9700 heatsink fan, or will just doing the cpu be ok? Check my sig for specs. Thanks!

The 9700 already has a mirror finish, or close to it. You should only lapp the 9700 if it's not flat.

Ok, I should check using a razor blade right? That is what I was wondering, cuz the Zalman 9700 is already super shiny. When I take it out I will see how flat it is. Thanks!

Yeah, as a general rule it seems that unless your CPU cooler looks really uneven lapping the cooler itself doesn't yield great results, especially if its Zalman

The mirror finish plays no role in whether he should lap it or not. But your second statement is true, he should lap it if it isn't flat.

So, I lapped my cpu! But, I didn't really notice any difference at all in temps. The Zalman website said optimal performance for thermal compound takes 7 days. Could that be why? Also is it ok to go crazy overclocking right after thermal paste is applied, cuz I just put it together about 15 minutes ago. Oh, and I lapped the corner of my thumb off too. I didn't notice cuz the sandpaper is so fine, but it kinda hurts now and it's all red and stings. Arrrrrrgggg!!!!!!!!

Hello, does anybody know if I am supposed to see immediate results after lapping, cuz my temps are exactly the same? Or will I have to wait a few days to see the difference because I put on new thermal paste? I used Zalman paste. Your quick response will be greatly appreciated!!!
