    That device looks unweildy and is undoubtedly exceeding the max weight limit intel or amd would want you to use for a heat sink. Quite frankly i don't see the point of a computer that requires you to fill it daily in order to run it. Overclocking should only go so far, they have some nice professional compressor based solutions that should be able to achieve similar performance without the hassle of purchasing dry ice on a regular basis. One I know is called vapochill. Dry ice with no load is around -75 C whereas the vapochill should be around -45 C

    And if you were to go the dry ice route, since AFAIK dry ice isnt conductive, why don't they just build the entire computer into an icebox (not the hard drive), and put a regular passive heat sink on the processor rather than construct that monstrosity of plumbing. I would think the overclocked memory and chipset would benefit equally as well. Oh and of course throw in some sacks of silica gel in there, don't want to have condensation now.:]

    You can achieve a temperature of less than -100 F just using a big stack of (LARGE) thermoelectric coolers. With TECs, you can keep your CPU that cool 24/7 without using up dry ice!! The hot end of the stack generates an incredible amount of heat though -- A large fan is needed to dissipate the heat from the monsterous heat sink. Your computer could be used as a space heater in the winter!

    1. Re:Thermoelectric coolers by Vo0k · · Score: 2, Insightful

      Sorry, but the cells will generate enough heat themselves, that no fan would be able to remove it all. Actually, in stack of 4-5 cells, the but-last (before the one sticking to the cooler) would likely explode, boiling. One, well adjusted thermoelectric cell, with really good cooling (water, really big fan) can be useful and actually decrease the CPU power. Adding the second one will already produce more heat than any commonly available solution (fans, water cooling) can remove. Maybe dry ice could remove the surplus heat, but then, why not use the dry ice straight on the radiator? It would be more efficient.

    Sure, more dangerous. But probably more handy to build and could last longer. Valve set to slow dripping, pipe outlets (possibly with some spraying tips) over the radiators, possibly even electric valve with some temperature feedback loop - temperature rising, pour more, temperature dropping too much, cut off. 1 liter is something like 6 cents in bulk, so it should last quite long. Sure pouring a bucket of liquid nitrogen over a PC won't do much good, but you should be able to release it as slowly as you only desire, so...?

  17. Use A Solvent by zeromemory · · Score: 2, Insightful

    Placing granular dry-ice into a copper container next to your CPU/GPU isn't going to result in very efficient heat transfer. If you're really going to try this, I recommend floating the dry ice in some sort of organic solvent (don't try water, as it'll freeze) and setting up some sort of agitator system.

    An even better setup would be to setup a water-cooling-like system, with dry ice in a container filled with solvent above the system. The solvent would be fed into a heat exchanger on top of the CPU/GPU. No pump would be necessary, because, as the solvent in the heat exchanger heats up, it'll float up to the top, where it'll be cooled down again by the dry ice.

    In any case, the costs of such a system would probably outweigh any benefit of using it.
