RockPro64 has a dedicated circuit for driving a 12V fan from PWM1. At the moment this makes fan spin at full speed. fancontrol can be used to control fan speed. E.g. the following config file works well: INTERVAL=10 DEVPATH=hwmon0=devices/platform/pwm-fan DEVNAME=hwmon0=pwmfan FCTEMPS=hwmon0/device/pwm1=../thermal/thermal_zone0/temp MINTEMP=hwmon0/device/pwm1=40 MAXTEMP=hwmon0/device/pwm1=60 MINSTART=hwmon0/device/pwm1=100 MINSTOP=hwmon0/device/pwm1=70 In the future it would be nice to define trip points in dts file, so that kernel could adjust fan speed itself.
