Hi, thanks for your reply. I think you're right about not having control but only reading. I have the same problem with Dynamix AutoFan too. Anyway, I gave the command root@Fujitsu-UnRaid:~# ls /sys/class/hwmon/hwmon*/pwm* /sys/class/hwmon/hwmon2/pwm1_auto_channels_temp /sys/class/hwmon/hwmon2/pwm3_auto_channels_temp /sys/class/hwmon/hwmon2/pwm2_auto_channels_temp /sys/class/hwmon/hwmon2/pwm4_auto_channels_temp
