My gaming rig (two 120mm, and one 200mm fans) makes more sound than the Mini R. I’m not the right guy to ask, I’m a old guy thats a little hard of hearing, lol. If you remove your drives do you still hear the sound?
I don’t know if the fan speeds can be adjusted…
Yes, I can hear it. It’s actually in other room in a basement. With drives as well. It’s not the sound, but repeating annoying whine. I already checked in IPMI and they run around 1700-1900RPM in optimal mode.
It this point I would open a support ticket and see what they say.
