I recently moved the fans on my h115i from below the radiator to above simply to make cleaning the radiator a bit easier. I did not touch the actual heatsink mount, and was pretty careful in the process, but after the move, it seems the unit is no longer cooling the CPU at all. None of the connectors changed, the pump still reads as active on the iCue panel, the lights still work, the fans still run, but the CPU immediately rises to 90+ when I boot the system up.
after paying very close attention, I do notice that there is a very slight "crunching" type sound from the heatsink / pump unit that sits on the processor that I did not notice before, but it is only happens for a fraction of a second, and then the unit is quiet.
the only thing I can think of is that the pump is somehow ceasing upon startup? Has anyone else run into these options.
When I was reinstalling the fans, the tubes running into the pump unit did rotate slightly, but it's obvious they are designed to do that, so I can't imagine that would be an issue.
