The following does the job for me, reducing the operating points to make the fan (normally) run at lower speeds: # cat /etc/rc.local the (single-) case fan is fan1 and its operating points can be controlled via pwm1.

once installed/ loaded, it will expose its sensor readings and tuneables under /sys/devices/platform/f71882fg.2576/.

kmod-hwmon-f71882fg is the necessary hwmon driver for me, providing the f71882fg kernel module as indicated by sensors-detect on a more full-featured general purpose linux system.

Just taking my case as an example (it will be different, but somewhat similar for you): This is usually sorted by the hwmon kernel modules necessary for your mainboard, the easiest way to find this out would be booting a linux live medium on your device (once) and to run sensors-detect there (as it has likely all potential hwmon drivers available and preinstalled), once you know what is needed - you can install and use it on OpenWrt as well.

That depends on the hardware (and to some extent its drivers).
