I turned on my pc last night and noticed my temps reached 70C+.
I realized my pump wasn't turned on. Most of the time I can feel it trying to turn on. It just feels like it's pulsing and then decides it won't go. Pauses for a second, pulses again, it may go and it may not turn on. Besides the aftermarket top, is there anything I can check inside the pump?
Troubleshooting wise, I've tried a different power supply, disconnected the pwm cable.
