Hello, a few hours ago I turned my system up with watercooling. Now it's under leak testing, but I was quite disappointed how loud pump is. Pump is simple DDC 1-T 10W 3900rpm, with EK top G3/8.
I disasembled and flushed it during installtion, maybe I did some mistake?
I never heard how pump works before, so I wonder is it normal?
Yowl from the pump is very loud actually
