My master cooler liquid lite 120 pump has ceased functioning. 5 months old. yesterday it started making horribly loud rubbing / grinding noises and today the pump will not start. the LED light come son but the pump does not function. I have tried powering it from the cpu fan and chassis fan pins on my mobo as well as straight from the power supply to no avail. The cooler master support centre gives me a chinese error message when i try and raise a ticket, the live chat is offline and there's no answer on the Uk support helpline. Any advice is much appreciated.
