Immersion cooling use oil or other dielectric fluid which doesn't conduct electricity as coolant. Which raise a question about possibility to sell those used video cards when mining will become unprofitable. Try to scrap and wash off oil off from RTX 3080 card. next users certainly wouldn't be happy about oily and smelly cards.Liquid cooling is nice but there is a problem with the electricity !
Yes, there are dielectric solvents (search for DS-100) that can remove all traces of coolants so the miners/GPU cards can be returned to air-cooled service.I'm curious about where immersed miners will sell their hardware after total 3rd party crypto ban? Do they expect wash those cards?
