So I just lapped my Q6600

wow! Impressive.

Steve258 Wet and Dry is for metal (and benefits from a drop of water at high grits). Sand-paper is for wood.
 
^^ so you're saying I've used the wrong papers to start with?

I bought them as part of a lapping kit for heatsink so I assume they must be wet & dry. How can you tell a wet & dry paper from normal sand papers? Sorry for my lapping n00bness.

Seems everyone has had a better finish than mine..

If you knocked 10 degrees off it, I'd say RESULT.
The angle the picture is taken at also makes a difference as does the light.

Have a look here.
 
Cheers think I'm just gonna leave it then.

From that link it looks like temp will reduce further still after the thermal paste has settled in.
 
I would like to give it a try on my p4 set up and would assume that the more you take off by sanding the better right..but how do you know how much to take off cheers ...davy
 
Not exactly. You only need to lap it until the surface is flat, ideally without taking too much off. You'll know when to stop because the copper surface starts to reveal as you are sanding it down. Use a coarse sand paper (200/400grit) to sand it down to copper surface then work your way down to finer grit papers. You should end up with a very smooth (although not necessarily shiny as in my case) copper surface, do the same with the heatsink base if you wish.
 
Yes av got ye..when ive finished configuring my new build quad/p5E when i buy myself a good cheap heatsink for the p4 iwill have a go,many thanks..Davy
