Putting a heatsink on video RAM

[MadEye2]

I've got a couple of heatsinks from my old k6-2 and pentium mmx, one copper with tiny fins, one alluminium with less and thicker fins (was the one on my k6 - probably why it was running pretty warm), and I' m wondering if I can attach them to my graphics card. It's an Asus Video Suite v9280 ti4200 - one side of the card has a giant heatsink stuck on it, but the other side the RAM is exposed (I presume it's the RAM - it mirrors the RAM placement on the diagram in the manual).
Total clueless newbie question, but how would I attach it (it covers 2 of the RAM chips), do I just need thermal adhesive? Is there a chance it would short circuit? - next to each chip is a tiny little metal thing with a red band that are ever so slightly higher than the RAM chips (are they capacitors?), and the pins for the RAM are almost the same height too.

Thanks

You can use thermal tape, or you can use thermal epoxy(sorta like a glue), or you can go ghetto and just use regular double sided tape. Or you can not bother, because it doesn't make any difference other than aesthetics.

Yeah, it might not do much with a sink but for two of the chips I have a fan blowing on to them and, according to smartdoctor, it's brought the temperatures down 7°c , but I don't how smartdoctor is measuring temperatures - is it taking the mean temp of the chips? I'm also concerned about the tiny capacitors that sit in between the 2 uncooled chips - it's a fraction of a millimeter taller than the chips and I'm worried that it may short. If I put a droplet of Arctic Alumina on the caps that should prevent any chance of shorting, shouldn't it?
Thanks
