Hi,
I bought a cable from Ebay to power my H110 water pump as well as the rear fan for a constant maximum speed rather than mother board variable fran control, I did it so I could have variable speed fans on the side of the case separate from the rear fan and pump which I always want to be on max.
When I plugged it in I tested it to make sure the fan span that was plugged directly into the power supply. It did not, so I checked the connections, unplugged them then plugged them back in again and tried again. Still nothing happened. I turned off the PC again and went to check the wires, the one that was connected to the water pump was hot, I guessed there was a short somewhere.
So I unplug the new cable and plug the fans back into the motherboard where they were in the first place. I switch on and the PC turns on for a about 4 or 5 seconds and then turns off before even reaching the bios screen.
I turn off and try again, it does exactly the same thing. wondering if the fan or pump were damaged I remove them from the board in case it's causing a failsafe. I try booting the computer again but the same happens, 5 seconds and off. I hope that perhaps the processor is just shutting down the computer due to a temperature failsafe due to a non running pump.
So I try one last time to plug the pump in and restart the computer. 4 seconds in and I hear a large pop and a flash of light comes from the board just below the pump roughly where the wire goes into the pump case. I wasn't sure if it came from the board or the actual pump, but I'm guessing it was the pump. The pump now smells of burnt electrical components.
Is there any way I can test with a multimeter to make sure the pump is definitely faulty, should there always be a certain resistance between some of the connectors on the pump/fan?
I'm scared now that my PC is also damaged, but I guess I won't know until I get a new CPU fan to test.
I also don't know if the pump was already faulty or if the cable caused the fault, it did seem that the new cable was hot next to where the pump plugged into it.
Can anyone help suggest what to do next?
Thanks.
Rob.
