i took the top off, the radiator is not hot, basically room temp. I dont know if there is sound, I can not hear it, the fans go as low as 40% and no lower. I do not hear water moving around
Then either the pump has died (happens often with AIO's),
or the thermal paste has gone bad, and needs replacing.
I recommend repasting first, see if that does anything, if it doesn't then the pump probably is at fault.
