I remember looking in the system devices and i remember that i saw the NZXT RGB & Fan Controller.
I left the USB from the NZXT unplugged so the fans would run 100%, because without the control the disks would obviously get very hot.
After i applied your update to the docker, i replugged the controller in, and it was found in the docker and started to work! I looked again in system devices and its still there. So i really dont know why it didnt work.
I also have the problem, that some fans keep at 0 rpm and dont take a change to, say, 30%. My solution was to unplug the usb so all fans spun at 100% and reconnect usb.
Also, my /etc/sensors.d/sensors.conf doesnt have any "nzxtsmart2" line, and even after adding a line manually it doesnt show.
Strange, istn it?
Thanks anyway!
