*SOLVED* Tools to lapp a CPU

post #1 of 21
Thread Starter 
Could I just use an electric sanding tool to get the surface of my CPU IHS completely flat?

Iv'e spent 2 hours trying to sand down the edge's and the sides of my CPU because it's not entirely straight and I don't want to spend another 2 hours doing the same thing again.

My fingers are in blister's as it is

You talking about a Dotco or a DA sander or what? Both of those sound pretty dangerous on a CPU. Not even sure either of those pads come in 3k grit

Yeah, something like that,I only want to very quickly bump it on the sander to get the surface 100% flat without hours of manual sanding

Uhm, I wouldn't use a sander, way to much potential for things to go wrong.

Honestly, It took me only ~ 2 hours to lap my q6600 and my old heatsink. As long as you do nice even, firm strokes it shouldn't take too long to get it nice and flat.

What kind of sand paper are you using now? I'm nearly 100% positive you cant get any grit over about 320 as far as discs and pads go.

On the back of the sand paper, the roughest one I got says P80 and the softer one says P180.

I use the softer one just to soften up the scratches after Iv'e used the rougher paper

Usually, alot finer grit is used that that. 180 grit is pretty rough. 320 grit would be best, there will still be visible scratches with 180 grit.
