Bought a Danger Den RBX, bit concerned about the review here with regard to fiiting it to an AMD (which I am about to do)

, the base has been hand lapped to 1200 grit, there appears to be what looks like black finger prints on one side. Yeah, a picture would be great but cant get hold of my camera just now... I'll add one just as soon as I can find it... Organised chaos...

I have read a couple of acrticles (googled) where people recommend NOT lapping actually saying that it would "ruin" the block. Some saying having a too flat a surface makes the thermal past "swim" between CPU and block (the pastes function being to fill the microscopic valleys in CPU and block).

Is there anything to gain hand lapping @ 1200 grit an already hand lapped block @ 1200 grit ?

I know higher grades of paper exist, finding them here in the UK is another matter. My local Hombases idea of "Fine" is 650 !!!

Also with regard to these accelerator fittings is the general consensus that a #4 is optimal ? (My system is - MCP600, Danger Den HC, Maze4 GPU, Z chipset, 1/2" ID).
