Is the extreme CPU idle temperature affected by the h100i pump issue?
Is the extreme CPU idle temperature affected by the h100i pump issue?
Is the radiator clean? If it is very dirty and there is no airflow over the fins, it cannot cool. Has this been cleaned out?
If the pump is reporting that it is running, than I would assume it is....if you disconnect it from power, I would assume it would report 0 RPM.
My guess is 1 (or more) of the following 3 things:
1) you have had a coolant leak and the unit is low on coolant. Unfortunately, there isn't a way to refill it unless you open it, which voids the warranty. You would need to RMA it.
2) you have an air lock. This occurs when an air bubble prevents the pump from moving coolant in a liquid cooling system. Since air is compressible but water is not, the air becomes a block that cannot be moved without manual...
It seems there is a pump problem. Connect it to the power supply molex using an adapter. Until then, avoid using the PC. If the pump remains connected to the power supply, consider replacing the CPU cooler.
Is the radiator in good condition? If it is extremely dirty and there is no airflow over the fins, it won't cool properly. Has this been cleaned before?
If the pump is indicating it's operating, then it seems likely. If you disconnect it from power, it should report 0 RPM.
My thoughts are on these three possibilities:
1) There might be a coolant leak and the unit is running low. Refilling it would require opening it, which would void the warranty. You'd need to send it in for replacement.
2) There could be an air lock, where a bubble blocks the pump. Moving the tubing or shaking the unit can help. It also depends on how the radiator is positioned—airflow tends to be better if the I/O tubes are oriented upwards.
3) The radiator itself might be dirty, preventing air from circulating and forcing the fans to work.
