Think my watercooling pump has gone?

Serial45 · 24 Dec 2018 at 22:14

So anyways I posted my machine today. Got a BSOD. Noticed my cpu temp hit 90c.

Thought that was strange. Noticed a big air loop in my system. Moved it around a little topped my coolant up. Same issue. As I bought my system pre built I don't have a great knowledge On this.

Anything else I can check for?

Thanks in advance

Is the pump making any noises?

I can feel vibrations from it. But nothing is moving and it overheats after a few minutes.

Heres my model of pump.
May seem like a silly question but will I get away without draining the system? Is there a hole into the reservoir from the pump side?.

OK so I've just increased the pump flow rate setting from 2 to 5 and it's making a lot more noise, but I don't seem to be getting a flow. I've tried moving the case around upside down etc. What else could be stopping the flow?

Also spotted a huge air bubble in my pipes. Ugh this could be it I've tried moving the case every which way to get this into my reservoir but it seems to be moving itself back into the radiator

Sounds like the motor itself is still working then, but perhaps the pump impellers have come adrift. Without a flow meter in the loop the only way to be sure would be to disconnect it from the system to physically test the outlet for flow.

You could have an air block somewhere, when you start and stop the pump, does the water level in your res go down any?

What Jokester asked.

If coolant level is different when pump is running than when not it is likely an air lock and not bad pump.

How old is your system?

System is around 2-3 years. But it's had little use some months I haven't even turned the machine on due to irl distractions. Pump impellors adrift? How can I check for this?

Not it seems static tbh. But I found that huge air bubble by moving the pc case around physically. I've topped up the reservoir via this method considerably. Probably took another 120ml so far.

Time to drain it down I think and have a look at the pump.

Again, what Jokester suggested.
With the age of our coolant it's hard to say what may be growing in the system, so draining and flushing to make sure it's clean is good idea. And while it's drained is good time to disassemble and check out pump.

Looks like it was some mammoth air lock, left it running at max flow rate and it seems to have cleared - phew!
Temps back down to low 30s.

Did you replace/fill system with distilled water?
