Gas Immersion Cooling
Use compressed gas to cool a PC

Using a compressed gas such as helium, then letting it expand into a sealed/airtight/airless compartment where the motherboard is, and taking it off the other side and recompressing it could allow for extremely low temperatures all across the board (pardon the pun) and, if you used a traditional heatsink for a forced-air approach, you could cool the CPU further. Sure, upgrades would be a pain, but if you could pull it off, and maybe color the gas, it would look cool and might even cool well. I thought of this after surfing and looking at liquid submersion. It cools well, but is expensive. Most liquid's problems are the dielectric property. Helium gas is nonconductive, cheap, nonflammable, easily compressed, and doesn't cause atmospheric damage. If it could be done, it might just work well.

       i've been thinking of this as well, but would rather find a common, cheap liquid that could do the job. of course, pure water is a great insulator but you can never keep it pure enough... maybe some vegetable oils? gonna keep researching till i find something that works, maybe i'll burn up a couple computers in the process but that's life.
