I don't understand why this was ever a thing when there's perfectly good water that exists like everywhere already doing a very good job of cooling things.
Everyone talks about leaks.... but that is a problem that can be solved especially with mass production. You could even have coaxial connectors where the water lines are completely inside of negative pressure line, with computer monitoring for everything, and it could probably be made almost as easy to connect as USB, and almost impossible to mess up because the system would leak test with air before it activates water.
- Nasrudith 3y agoThe goal was to reduce energy and water usage. It is the difference between "takes a whole stream's worth of water a day" and "doesn't use any water". But PFAS are of course too problematic.
- eternityforest 3y agoI still don't quite get it. If you can closed-loop reuse the nasty PFAS, can't you also just reuse the water? From what I can find it seems like immersion cooling just uses water anyway to cool the coolant, why not cut out the middleman and just run the water through a water block?
- dessimus 3y agoImmersion means the entire computer, motherboard, cpu, gpu, ram, etc. is in the liquid, not just piped to waterblocks attached to specific areas to wish to cool. You cannot do this with plain water as it is conductive enough to short circuit the computer. If there was a way to use distilled water, they would have figured it out long before using the PFAS chemicals.
- ksec 3y agoThis is specifically about 2-Phase Immersion Cooling. They are used because they have a low boiling point, turning into gas before turning back to liquid ( Hence 2-Phase )
