Hello there, I recently bought a Koolance PMP-400 ddc pump and a EK-DDC X-res 100 CSQ pump top/reservoir about one month ago. I notice that my pump has stopped working and when I try to start it, it will spin for a bit before turning off. I have seen it gone through several of these cycles. Any help is greatly appreciated.

Update: I am powering the pump using a 12v molex cable. I have an 850w power supply. I have managed to get it running earlier today, though it took several tries and power cycles. It seems to be working fine for now. Should I RMA this unit? I am worried that it might fail on me again as I was lucky to notice that my high temps before my components fried.
