lapping CPU

Slinkie · 6 Feb 2009 at 10:41

Hi Folks,

I am half way through lapping my CPU water block using the instructions I got in the lapping kit. I am using a number of different grades of sandpaper on a small piece of glass and using water as a sort of lubricant.

I am going to lap my CPU next but was thinking about the process, do I still use water or do I just use dry paper? I don't like the idea of rubbing my CPU in a pool of water

Cheers

Matt

maybe a very very small amount of thermal grease as a lube?

May not work but i would prefer using that to water.

just a drop of water is needed fort a mirror finish, protect the cpu pins by using tape.

use the same method but be a lot more gentle and precise and use less water. as long as its dry when its used it'll be fine.

same here i used a small amount of water when doing my cpu, just clean the paper often.

I lapped my CPU completely dry, worked fine. I didn't get a mirror polish finish, but it really doesn't matter as long as it's flat and scratch free

I used a piece of an anti static bag and tape to cover my cpu when I was lapping with water.

or the plastic cover that comes with cpu if you still have it

That's right (although it seems you don't get that black backplate with newer Wolfdale CPU's?). I also seal that backplate on with some low tack masking tape and always lap CPU's dry, light 200-grit, then 400-grit and finish with 600-grit I think!
