I've found that cautery and he's got something there about laping the coppermine but the link he's got there doesn't work so I don't know. i do reemeber reading, I remember because it was so bloody long. well I'm getting the orb tomorrow so see what happens. it's just i was reading about lapping the old P!!! and celeron and temps were dropping up to 10c but as you said too dangerous, I just wanted a smoother surface and better contact for the heatsink
