hey smarty pants... i'm talking about the FINISH ON THE BASEPLATE, not the baseplate itself, not the material its made out of, not the dimensions, not the design, but the finish on the surface of the block
this thread is just to prove that a mirror finish doesnt always mean that something is flat, and when it comes to heatsinks, waterblocks, etc., having a flat block is MUCH more important than having a shiny block - but if you can create a mirror finished surface that is also as flat as possible, then that is the absolute, no questions asked, best way to maximize your performance gain from lapping
and here's one fucken hell of a mirrored surface (the IHS on my 3.0E P4), finished to 10-micron sandpaper:
and to prove its flatness to you:
btw, i used the premium lapping kit from
www.easypckits.com to achieve this finish... plus i had ALOT of prior practice with lapping to ensure that the surface was 95% flat or flatter
