Hmmm, alcohol is non electrically conductive? It sure is flammable =/
He could use Hydrofluoride I believe it's called. It's a non-conductive liquid.
Yoshi used it on the screen savers but he had a system pumping out that liquid through an intercooler sitting in dry ice, and then after it went through that was pumped back onto the CPU.
Was crazy to just see the CPU sitting there with no heatsink in a tub of liquid
When he turned the pump off that caused the jet of liquid to stop from blowing onto the CPU you could see it causing the liquid to boil lol, mind you it has a low boiling point though
