The 9 year old Corsair H100 AIO cooler that I am using is playing up. The pump is repeatedly getting airlocks. The cooler starts working again after rotating the radiator around the pump. I'm guessing the water in the AIO has probably evaporated. Looking for a way to refill it.
It's probably time for a new cooler anyway and am wondering whether I should go back to using an air cooler as they run forever. The difference in performance between an AIO and air did not seem to be huge.
What sort of cooling are you currently using?
