Exotic case design solves computing heat issues..

[HTRN]

There are several liquids out there that are designed specifically for this purpose, but at last check they cost about 50+ dollars per gallon.

Flourinert is the big one, I forget which version is used, but you're low in your pricing - it's stupidly expensive, like 500 bucks a gallon. The price is so high, and Flourinert is so hard to get ahold of(honestly, the best way seems to be Ebay), that most just use mineral oil.

The crazier overclocker types have been doing this sort of thing with PC hardware for a decade at least that I'm aware of.

Yeah, I remember seeing somebody using Flourinert as a heat transfer liquid and liquid N2 to cool it. The difference here is that it's a nice neat kit that doesn't look like something pieced together from stuff under the workbench.

Ol' Seymour tried mineral oil, an ethanol/glycol blend (basically aircraft deicing fluid), and about a dozen other things including triple distilled water; but they were all either too reactive, didn't circulate properly, or didn't have the heat moving capacity.

Hey, when you're selling supercomputers to the government(A cray 2 was what? almost 20 million in 1985?), justifying coolants that cost 500 bucks a gallon isn't hard.

And oh, for those who are interested - serious overclocking using liquid Nitrogen.

Doesn't mineral oil tend to dissolve the prepreg?

There may be some encapsulant but the prepreg solvent resistance would depend on the particular resin system used.

What kind of work do you do Slowpoke? Not often I hear prepreg used in a sentence outside of my work.

Yeah the 'supercomputers for the gov't' market was very lucrative. A certain part of Cambridge, MA had a bit of an economic collapse in the early 90's when that particular teat dried up. I once applied for a job (nothing cool, glorified gopher but I needed a job) at Thinking Machines, just before they imploded....

Heck, even SGI is basically gone...
