NASA heat tile.....

[Exa.bit]

Would it work? The tile itself would not get hot that's for sure but would it actually remove the heat from the die. What do you guys think?

[alexio]

I thought about this, but we need the thermal properties of the material to now for sure.........

[Fairydust]

It's part of a heat insulation system, which would suggest it better be a terrible conductor of heat.

[Vapor]

Yeah, at one inch thick it can withstand sustained 600C temps and you won't feel it on the other side......horrible conductor of heat (by nature).

[IYP]

yeah it would make good insulation but for transfer it would like packing blankets into the side of your case

[Vapor]

That and making contact would be a :banana::banana::banana::banana::banana:....it's a very foam-like substance that actually leaves a powder on your hands if you touch it.

[trakslacker]

well, that solves that. Case closed, chaps!

What do you guys think about adding some diamond powder to AS5 or better yet making your own paste that is say 95% diamond powder?

[Vapor]

Mmmmmmm, diamond slurry

[Fairydust]

The major factor of diamond's amazing heat conducting capabilities is it's compressed crystaline structure. A powder will perform a lot worse than a single crystal, but I can't even guess at what level. Might be wort a try.

Actually this has been covered at GREAT length by one of our members by the name of oublie. He had even been in repeated contact with the guys over at Arctic Silver. Trust me it's been tried before Bottom line is that if ti worked, someone would already be selling it, althought oublie did appear to have a compound that initially performed slightly better than AS5, although it was hinted that the mixture may have detrimental effects on a HS base over time.

Here's the orignal thread:

EDIT: It's OT to this conversation, but if you really want cooling supremacy, you should do a search for Chilly's duiscussions on using liquid helium in a cascade.... ;)

heh, thanks for the link. Still seems like a good idea, with alittle more R&D it could prove to be very effective. I was also considering embedding a diamond plate into a waterblock. With the thermal properties of diamond I dont think the block would need major machining. Something along the lines of this.

Let me guess that has been done too. If so guess I'll have to go all out and make a all diamond evap. I wish :slap: :slobber:

[trakslacker]

i dont think that's been done, but you should know that diamond's thermal conductivity properties can change significantly(for the worse, usually) depending on how it is crushed/pressed/altered. While pure diamond is better than almost anything out there, diamond dusts or powders just don't work the same.

[Flanker]

The cost of cutting the diamond into slabs might be more expensive than the HSF itself. Diamond is the strongest substance on the planet you know...

actually its not, a while back some guy discovered this. even though its only .3% denser its still is :) linkage http://www.newscientist.com/article.ns?id=dn7926
