hi,
i was wondering if the compound gold oxide would be a good thermal paste? my mom works for a fuel cell company and they use lots of heatsinks and stuff and she says they might have some paste, but she wasn't sure what kind. silver oxide is artic silver right so if i can get some gold oxide if there is such a thing would that be better?
 
lol
well i hope my mom goes to work tomorrow and gets me some HEH probably expensive so i will have to jack lots of it 🙂
 
First off, gold has a lower thermal conductivity than silver. And compounds i.e. "gold oxide" will have an even lower thermal conductivity than that. Sometimes the oxides are much lower, like in the case of zinc oxide that you find in most thermal compounds. It falls by a power of 10 almost.

Lets us know the results though, I am curious.

I have heard of someone thinking about using a few sheets of gold leaf as the thermal junction because its so maliable, but I am not sure you could get it to fill the microvalleys in the surfaces, but I would sure like to see someone try it in a scientific test versus other compounds.

Honestly I would like to see anyone try a scientific approach to thermal compound testing. It entails more than any test I have seen except the smaller one on Arctic Silvers site where they actually took into account that if you have applied a compound it is still in the microvalleys of the heatsink and either must be relapped or cleaned with a non-greasy solvent. But until then I think I will stick with Arctic Silver II, mainly because I have never seen it dry out and I have seen cheaper compounds turn to powder where they obviously wont be filling the microvalleys, which is their job. I run an Athlon at 1.433 @ 2vcore, I certainly don't want my thermal compound failing or cooking away.
 
Err... "gold oxide?" :Q I don't think you will be able to get any, for this reason.

edit: if you want to try for something exotic... try for diamond-based thermal compound. Solid diamond has a thermal conductivity of about five times that of metallic silver, if I remember right.
