Full Immersion Cooling Comes To Desktop PCs

mr_sifter writes "After three years of research and around £100,000 of R&D costs, UK-based Armari has unveiled its XCP prototype. It's a full immersion liquid cooled PC which supports standard ATX components. Unlike conventional liquid cooled PCs, the components are all easy to swap in and out as they're swimming in liquid, rather than under waterblocks. It also looks amazing, pumping around 70KG of electrically inert cooling fluid (salvaged from an old Cray) around its military grade perspex shell."

      Fluorinert is not one chemical, but a family of them marketed under the same name. This machine uses PF5080, which is also known as perfluorooctane.

      The case you have likely heard about relates to perfluorooctanoic acid (PFOA), a related but distinct chemical that is used as an industrial cleaning agent, and also in the process of applying teflon coatings. There are concerns that it could accumulate in the food supply, and that it would be carcinogenic in this case. This led to a californian state senator to call for a ban on the use of all perfluorocarbons (the group of chemicals that contains both PFOA and PF5080) in the food industry. The call has not lead to any action.

      FWIW, perfluorocarbons, including some variants of fluorinert, have actually been suggested as anti-cancer drugs, and PF5080 is being considered for use as human medication (as a vector for delivery of anaesthetics). Rats have routinely survived being immersed in oxygenated PF5080 for prolonged periods with no ill effects. If you've seen the film The Abyss, you've seen a rat breathing PF5080.

      PF5080 is safe. I'm pretty damned sure of that.

      OK, that last sentence might be misleading. There is a bill in-progress in the californian senate (SB-1313), which will ban "perfluorinated compounds" from use in food packaging. It looks likely that it will pass.

      (b) "Perfluorinated compounds" means perfluorooctanoic acid (PFOA)
      or perfluorooctane sulfonate (PFOS), or PFOA- and PFOS-homologues
      that differ only in the length of the fluorinated carbons and contain
      more than six fluorinated carbon atoms, or chemicals that are
      reasonably suspected to degrade in the environment to PFOA or PFOS,
      or PFOA- and PFOS-homologues containing more than six fluorinated
      carbon atoms. "Perfluorinated compound" includes all acids, salts, or

Basically, don't bother buying today because you'll get the same amount of work done in the same amount of time simply by waiting for a faster computer.

      This fluorinert jobby is probably whisper quiet, but I don't see anyone racing to order one. In a Cray, the liquid made sense because they were huge machines and it wasn't realistic to even try to cool them with air. Today's computers are reduced to a single board, with a few very localized heat sources.

      Having a big body of liquid will actually hinder the heat dissipation, because the liquid moves far slower than air, and your CPU is putting out 100+ watts of heat in a tiny area, or in my case 350 watts, turning the area near the CPU into a mini deep fryer - definitely not cool!

      Given how today's air coolers can run whisper quiet (at stock speeds and voltages), I just don't see where immersion cooling could possibly fit in the PC market. It doesn't work any better than a high-end air cooler (Ninja or TRUE120), doesn't overclock anywhere near as well as TEC+water setups or phase change, and costs 50 times more.

    Water has the highest heat capacity of any common liquid. It takes more energy to raise the temp of a given amount of water one degree than for any other substance. High heat capacity is one reason it is so efficient for power generation and cooling.

    For example, one BTU of energy raises one pound of water one degree F. In metric units, the specific heat of water is about 4185 J/kg/K (15C). Whereas the specific heat of Flourinert is about 1049 J/kg/K, or 24% of water. OTOH, Flourinert is about twice as dense as water (1.85). This means that the flow rate would have to be 2.25 (1/(1.85*.24)) times that for water to remove the same amount of heat, given the same temperature drop. I would have guessed that Flourinert would be a better heat remover at such a high price. It's utility comes from its inert nature in an electronics environment.

    Deionized water is also a good electrical insulator as well as the best heat transfer agent. But with the wide variety of materials in a pc, some would dissolve and cause water to be conductive. Shorts.
