Yea, i have the same problem with this pump (which is what brought me here).. It's not like a dark, fan-like sound, but rather a high-frequenzy REALLY annoying sound coming from the pump. I DO NOT have any air bubbles, at all, and even though the pump/reservoar is not 100% full, there is no air coming into the pump. Its really just the engine making a frustrating noise.. I'd rather listen to the reference GPU fan than this
I have a fan controller, which on i set the radiator fans to max, and THEN i barely hear the pump <3. But those fans are loud too, so: is there a way to kinda "isolate" using rubber or something, to fix this? A friend has the same pump/res (wc kit) and has the same sound..
Does the noise get better? Is this usual? Can it be fixed?
