Attaching a heatsink to a video card's 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 also get thermal tape (Radio Shack may sell it, not sure), but it's not as good as the adhesives. However, it should be easier to remove.

Thanks, should I be worried about the sink being so close to the pins and those tiny capacitors (assuming they are caps)? The capacitors are very slightly higher than the chip itself and i'm worried that the sink will short circuit them.

If the heatsinks are going to touch those "tiny caps" which are higher than the RAM itself... that would mean that it's not going to fully cover the RAM, correct? In that case it's pointless. Try to modifiy the sinks or position them so that they contact the RAM and only the RAM, and don't worry about all the little metal wiring around the RAM (just don't get thermal compound all over them).

Well, it's and old CPU heatsink about 5x5cm, it'll cover 2 of the chips fully, but theres a cap inbetween them and they're a faction of a millimeter higher. Same for the other 2 RAM chips
