Kmod-hwmon-pwmfan file

Installing and Using OpenWrt
1

I installed kmod-hwmon-pwmfan on my rockpro64 to get my tiny CPU fan going. It now runs at 100% and I am thankful but I want to change it to 80% for the time being or setup HWmonitoring so it's only running at 100% speed when it needs it.

I've found suggestions online like looking in sysfs, fan_control1, or pwm_fan, but I can't find any of these locations.

Did you try:

  • /sys/class/hwmon/ :point_left: (Other OpenWrt threads list this one)
  • /proc/acpi
  • /sys/devices/platform
  • /sys/class/drm
