Anyone experiment with the PCI extenders and immersion cooling? It would require a fraction of the liquid that's normally required. Might make monetary sense.
you mean instead of this:
http://www.pugetsystems.com/aquarium-computer.phpyou turn the motherboard upside down and dangle the video cards in a smaller (much) tank? that's an interesting idea.
if you go to the puget systems site, they have parts that can be sourced back to the primary vendors. the radiators - as always - would be the key: but i'd imagine you could use smaller ones. their systems are designed for extreme gaming - so the CPUs, RAM, PSU, etc., are maxed-out. with a couple of 5990s (their V. 3 test platform), they're probably putting 70% into cooling the GPUs. you could probably use half the volume of mineral oil, and a radiator that was considerably smaller and cheaper.
stopping the oil from creeping up would be an issue.
hmmm...
