Hello All!
I am having trouble with alphacool 360mm kit, I have built correctly accordingly:
Pump/Reservoir ----> Radiator ---> Heatsink ----> Pump/Reservoir
I can hear the pump working, it's connected on the cpu fan connector, but there is no flowing water!!!
My CPU temperature is going 89ºC!!!

I think the faulty pump is likely the cause. If you can still hear it working but no water flows, it probably isn’t moving the water.
Are you certain there aren’t any obstructions or twists in your loop? Do you have a single connector facing backward?
Also, try not to operate your rig until this issue is resolved, as you don’t want to cause any damage.

Also, avoid running your rig until this issue is resolved—don’t risk damaging anything.
