wet and dry, and halfords mate.
get a good lapping guide, and buy a mixed pack, as you will need various grades of paper.

Start of with some 800 grit stuff if its really rough and then some 1000 and then 2000 grit stuff. Yes halfords stuff is good.
If its not all that rough and fairly smooth to start with try a nail file, an emery board I think, the really smooth ones.
If it's really rough and most importantly concave, start with 200 grit paper and go at it until you can see a lot more copper. Then move onto the 400, and 600.
Im sure there have been tests showing that lapping to over 600 grit is worthless, and the mirror finish is only for willy waving on the net. It's to do with the minimum size of the particles in the thermal paste used being larger than the pits and scratches in the lapped surface. e.g. polished and sanded with 2000 grit.

Tape the paper onto a piece of mirror that is placed on the table etc. Mirrors are very flat.
Work the heatsink on the paper with water for lubrication. This way you will soon see if the heatsink is flat or concave/convex.

Thanks for replys guys,
Went to halfords today and got some sheets of 800 and 1500 so im hoping that it will be ok, really cheap too less then £3.50!
They have got a 'project kit' too, which has a selection of loads of different wet 'n dry stuff + some aniti oxide sheets too, but the wet'n'dry only went upto 1200 so i never got it. Was only 4.99 aswell!

CPU load
Before 36
After 31
I also did my chipset cooler -load (Thermalright HR-05 SLI),
Before 52
After 39!
Howerver, I also moved my 1800xt from slot 1 to 2 as before the accelero x2 cooler was blowing hot air directly onto the chipset. Ive also had to completey romove the rubber protector that sits around the bottom of the heatsink. I must have put it on at a bad angle last time and the rubber had gone all over the base!
