Liquid leaked onto the Board while it was powered up .....or was it possible still "wet" when you energized?
Set it up out of the case and test....if you got liquid on your Board while it was energized........may be out a Board...but set it up on a table and try it out...just ensure everything is bone dry prior to energizing.....Ive gotten liquid on my board before but I let it dry for a day before I energized it....was fine..

Rubbing alcohol doesn’t cut it for electronics, must be 99.9% variety which will evaporate quickly. Then the water bath? I’ve been an electronics engineer for better than 30 years and this is the first I’ve heard of bathing electronics in any type of water be it purified, distilled, deionized or blessed by a shaman. Submersed in mineral oil, yes but water no.*
The non-conductive coolant may be less conductive when you put it in but becomes very conductive later on as it picks up trace metal from the heat sinks and fittings.*
I’ve gotten things wet in the past (not when there was power on it) and simply sprayed it down with 99.9% alcohol electronics cleaner then Left it sit for an hour or so then into a plastic bag with a generous dose of rice or silica dessicant to pull out any possible remaining moisture overnight. The 5V standby is still very much active and always present. Pin 20 on the ATX connector has no connection.*
I’ve had boards cease to function just by having the 24 pin ATX connector pulled with switch bridges to run a leak test. If I could get board schematics I could explain why. Im so paranoid with it now that I have a jig set up that has its own cheap PSU and switch just for leak testing so I don’t have to mess with anything but wiring to the pumps.*
It would be prudent to pull it from the case and test it that way with as little as possible connected. All it takes is a pinched USB cable to bring everything to a halt. *
