For me the problem was only the lack of the fancontrol executable, everything else seems to work (although I can't tell if pwm or not). So I thought I'd share this that might help keep still working hardware from being perceived as non-functional or obsolete: for the moment Armbian (Debian 12 Bookworm, Minimal / IOT) + Omv are working perfectly! Thank you Igor! Riccardo

After installing armbian bookworm the fans are always at maximum. Here is how I solved. Trying to figure out what is not working I try to run the related service systemctl start fancontrol.service but it does not start. So I check the latest errors: systemctl status fancontrol.service I obtain Failed ...fancontrol.service: Failed to locate executable /usr/sbin/fancontrol so, fancontrol is simply not there and apt can't find it for installation. I took the old sd card and copied the fancontrol to /usr/sbin/ Than make it executable with: chmod +x /usr/sbin/fancontrol than systemctl start fancontrol.service systemctl enable fancontrol.service As soon as I started the service, voilà, the fan started to... blowing only when needed: problem solved! Attached you find the fancontrol file. fancontrol
