The computer is very quiet in all load scenarios:
Radiator Fan Speed: 750RPM fixed / RAM Fan Speed 700rpm fixed / Pump Speed 2300RPM fixed.
GPU uses Custom Fan Curve capped at minimum allowed Fan Speed (1100RPM) -> 55C maximum, impressive cooler!
No Coilwhine.
Built my own AiO with the Alphacool Eisbaer Solo, 240mm radiator and Legris fittings/hose as the AiOs
available on the market and their pumps are far too noisy for me.
