Volcano II - lose the pad?

[Guest]

I just purchased a Volcano II for my new t-bird 1ghz. I plan to do some overclocking on an Iwill KK266 but not gonzo. The Volcano comes with a sticky pad on the sink. I take it that pad is less effective then a thermal compound so it should be removed. yea or nay?

Whats the procedure here, work the pad off with a razor blade then use ISO to remove the remaining residue? Is that effective? Oh and what the heck is 'lapping' and does it matter.

Gracias, D

Yes, thermal paste is better. Get some Arctic Silver II, it's like 94% silver, or something crazy like that. Make sure you only use a tiny bit on the core.

Lapping is roughing up the surface with sandpaper, as I understand it.

My test showed that the solidified thermal compound is just as effective as Paste on the ontouched cooler. But buffing the bottom of the heatsink helps make it work better, and that requires removing the compound.

BTW it is not a pad, it's a really thick paste, kind of like a high-temp wax.

I ususally scrape off coumpound with a pocket knife, then wash the thing with HOT soapy water (works great), then buff the bottom with a Scotchbrite pad.

Lapping is flattening and SMOOTHING a surface. While you could roughen up a smooth surface by lapping with a coarse paper or compound, most often lapping is done to get two surfaces to make better contact for sealing (valves and valve seats) or heat transfer purposes (HSF's). Crashman's polishing with Scotch-BriteTM (I work for 'um so got to do the TM thing, heh-heh) is probably a good idea just to clean and deoxidize the surface, but make sure the last thing you do is flush w/alcohol and wipe with lint free cloth or lens paper.

Search on lapping in this forum for other ideas if you really want to do it. 600 grit is about as far as you need to go. Flatness is just as important, so you have to make sure you use a flat back-up and keep the HSF flat against it.

I don't believe I've seen anyone recommend Avon's Skin So Soft, but it works well. After removing the bulk of the pad with a knife (fingernail?) or other implement, I wipe off the remainder with Skin So Soft then wash the base of the HS to remove the solvent. BTW, Skin So Soft works great at removing dried paint from your skin. Plus it's a lot gentler on the skin. <g>

Well, charcoal lighter works good too. I use it to remove all sorts of gummy stuff.
