i cant get a handle on this whole lapping thing, i tried to do it using my dremel mini drill, and i ended up having to take maybe 1/8 inch off trying to get it back to where it was....anyone got a good tutorial, with pics, for lapping?
err..I don't think a dremel mini drill is the correct tool for lapping?...you want a sheet of glass or mirror..then you want some fine grit wet/dry sandpaper...for cpu lapping 1500+, for heatsink lapping 600grit - 1000 grit.
Tape the sandpaper to the glass (face up) and wet it...for a heatsink, start with a coarser grit, (I used a 600) sand it in a figure 8 motion or alternate between side to side and up and down. Finish it with a finer grit (I used 1000) make sure the surface is even.
The whole idea of lapping is to ensure an even contact between cpu and hs.
Check the front page (
http://overclockers.com/ ), I'm sure there are more in depth explanations regarding lapping w/pics.
As far as the gorb goes, I have one. I haven't used it and probably won't ever, my husband might mod it for his video card, but so far, it's a conversation piece.
I have a fop32 on my p3 550 @ 770, temps hover around 40 celcius. I haven't lapped either the hs or the cpu...before I added the Arctic Silver II, my temps were closer to 50C.
