Just got one of these recently. With ECO mode @ low load the PSU is quiet, but with ECO mode off, it's easily loudest item in my system at low loads. Fan seems noisy. Sounds very similar to my RTX 3080 FTW3 when it's fans are set to 75% (1925 RPM), but a bit higher pitched than the gpu's fans.
Does anyone know what the RPM or expected noise level is when Eco mode is disabled? Does it just run at 100%, or is there some load/temp based nuance to it? Product page has a noise level curve with eco mode on, but not when it is off.
