Lapping ?

[BIGBC]

Just read the Lapping guide here - http://forums.overclockers.co.uk/showthread.php?t=17803239

I had never really come across it before which got me wondering wether or not its widely practiced or that advantageous ?
Is it a suitable process for a Q9550 or Q6600 ?
What sort of effects would this have on my air cooler? (ill attatch a picture below) surely that clip would just force the contact further down anyway, would the pressure change much ?

In the pics weescott seems quite happy about touching the underside pin contacts which is something I had always avoided just thinking its best not to, can any damage be done by touching/pressing on them ?
As water is used in the process is there any danger of damaging the CPU with the water ?

Any answers would be appreciated

Oops, I was just curious and a tad eager on the posting.

heres my heatsink mount -

surely that would apply enough force for the slight height change to not matter - or is it a greater height change than I think ?

Ive just read 6 threads about it and it seems a lot of people have done it to the cooler/CPU and gained from it.

First 2 questions have been pretty much answered - lots of people doing it to Q9550/Q6600 and the effect on the cooler mount isnt very noticeable.
But no real answers for the latter 2, have seen a few posts asking whether breaking a CPU during lapping was related to water/oil which is kinda worrying lol.

Qood point about the warranty, not sure wether its worth it on a 2 week old chip . . .

well my current temps are -
idle - 40 - 33 - 41 - 41
full - 53 - 45 - 51 - 51

Im yet to overclock it at all but am reading up on it now. Wouldnt hurt to drop those extra few degrees anyway . . . unless it dies further down the line =[

My heatsink is mirror finished, unless its bowed in any way i really wouldnt want to touch it as the surface finish is near perfect.

I think I'll get a decent overclock going and see what the temps are first, then decide whether or not to lap it.

Wet and dry works better wet, pretty much. It'll also stop you getting metallic dust everywhere, which is a good thing as it avoids shorts.

Putting the little plastic square back on the chip, and electrical tape around the outside to hole it to the chip and seal around the edges gets my vote. Lap it, then clean the surface to remove dust, then remove the protective back cover. This way you can indeed lap it dry with no issues

Cheers for that. Im not supposed to be pressing the chip down am I ? Ive heard it said that Im just letting the weight of the CPU do the work (which i can see taking a lot longer).

Ive used wet and dry a lot and the water/oil really does help get a polished finish.

Ill try it on my old Q6600, dont want to lose the warranty so early on.
