My PR22-D5 pump is not working. I ordered it a few weeks back and I'm finally completing my build and I went to turn on the pump and nothing. No sound. No movement. Nothing. Dead as a door nail. My power supply appears to be fine as the motherboard lights up so I have reason to believe the power supply is fine. After researching the pump and much googling, I am wondering if I am not wiring it correctly. It's a molex connector and the wiring is red/black which implies 5V. I find this odd because the underlying lian d5 pump says it wants 8V-24V. Also, other brands that use this pump appear to come with the yellow/black wiring which again implies 12V not 5V. Very confused. The pump could in fact be dead. But I find that hard to believe...
