Wouldn't the CPU benefit a bit more from a higher surface area (ala heatsink) ?
Das Rig, Ja?

I have actually emailed them and asked about a sample that maybe we could have 1-2 members try out. I know we have a few members that would be willing to take this stuff and do something extreme but OCN style. who knows maybe we could help them by doing it and find a way to better cool the stuff.

Yes - some exotics used such cooling. Cray built a specal machine for NORAD that ws cooled with human blood plama substitute - and I only know of a handful of pictures ever taken on that beast. I think the cost of the fluid would put it out of the budget of most home hobbyists - but of course, the ones that resort to LN2, well, they are probably to macho for boiling points that are in the positive set of numbers...

Yeah I think something like this would be perfect.

a 1U copper passive heatsink. It would increase the surface area by a lot.

Mineral oil has a problem with slowly seeping through wires and getting out of the tank. I wonder if this chemical does the same thing?

There is a post on youtube claiming that this chemical is $1500 for 3 gals.

I'm thinking the noise from vibrations and boiling would be pretty quite, boiling oil is pretty quite.

Could you submerge your hard drive in this too?

That's RIDICULOUS!!

As if this stuff is made of liquid gold or something, people need to get real...

You can't market a product that cost $300+ a gallon even..

Even $200 a gallon is too steep, $40-$100 would be reasonable...

Bottom line = FAIL...

This is certainly a lot better than using cooking oil.

Application Guide
Listed below are key applications for HFE-7000. Documents specific to the application are listed to the right.
Heat Transfer Fluids
HFE-7000 is pumpable to -120°C. This property makes it useful as a heat transfer liquid for cooling reactors in the pharmaceutical and chemical processing industries. In the semiconductor industry, it is ideal for automated test equipment (ATE) and wafer processing equipment which requires extreme low temperatures. It has also been used as an autocascade refrigerant. Novec fluid HFE-7000 has a very low global warming potential (GWP) and offers reduced greenhouse gas emissions when compared to PFCs - without sacrificing performance.

sorry for the double post. i have been in contact with my local 3m rep. he is getting an exact price per gallon for me.. might be cool for some awesome mods.. i will report back when he calls me back with details.
