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.

Possibly a blockage in the loop. Worth dismantling your blocks to check for gunk.

If it's an XSPC top it could be fouling the impeller. Why fit another top when the stock one is one of the best?

The pc did sit for a few months drained but I kept the pump moist. I took all my blocks apart last week and scrubbed them out. I didn't touch the pump though

Was feeling a bit lazy

Reason I went with the EK-DDC X-TOP V2 was purely aesthetics.

Could be an airlock then.

You will know if it is spinning with an air lock, it sounds like it is trying to pump gravel.

Drain loop, take pump apart, check for any fouling or visible damage. Then try running the pump in a test loop (beware, they are powerful beasts - I soaked half my apartment doing that once).

If that fails then it is sounding like there is a problem with either the control board or a coil has burnt out. There are some repair options if you have decent soldering skills.

I forgot that it could also be a problem with the molex plug giving an intermittent connection.

I had this problem when I was running 2 pumps separately and the second one often wouldn't start up. In my case it was due to plasticiser in the CPU block that was gradually building up.

Thank you, I'll give that a whirl this weekend.

I checked the molex,looked fine but I'll consider all my options. Thanks!

Looks like my pcb is bad..

Does anyone make a repair kit for the 35x that allows me to keep pwm?
