Need help....my liquid cooled system is making a clicking sound. When I unplug power to the pump and the coolant stops flowing, the clicking stops...I am not sure if it is my flow/temp meter but when I lean close to the system it sounds very close to this area. Any insight would be helpful. I am planning to flush the coolant and replace it to try and fix this... but I will admit I am newer to liquid cooled systems and custom built PC's so please be understanding of my limited knowledge. The system has been in place for a long time with no clicking, this just started a couple days ago. See the below video for audio of clicking sound. It is not the fans, I stopped them to check if that could be the issue.
