The INTEGRATION_GUIDE.md reports: QUOTE View Current Configuration sysctl -a hw.rpi5.cooling_fan END QUOTE But there is no such in my experiment with the fan control: # make -f Makefile.rpi5 load /sbin/kldload -v /root/Rbcm2712: AVS thermal sensor mapped at 0x107d542000 bcm2712: RP1 PWM1 controller mapped at 0x1f0009c000 bcm2712: RP1 PWM1 clock enabled (CTRL=0x10000840 DIV_INT=8) bcm2712: GPIO45 CTRL before=0x85 (FUNCSEL=5) bcm2712: GPIO45 CTRL after=0x80 (FUNCSEL=0, pwm1) bcm2712: Thermal sensor initialized Pi5-fbsd-kernel-fan-control/rpi5.ko rpi5: Raspberry Pi 5 board support loading rpi5: Cooling fan thermal management started L/RPi5-fbsd-kernel-fan-control/rpi5.ko, id=3 ("-v /root/Rbcm2712:"?

I've not checked. I set up: # # Have experimental cooling fan control always use full speed sysctl hw.rpi5.fan.temp0=0 sysctl hw.rpi5.fan.speed0=255 sysctl hw.rpi5.fan.speed1=255 sysctl hw.rpi5.fan.speed2=255 sysctl hw.rpi5.fan.speed3=255 It does have the fan spinning. (I've not checked if loading or use is well protect against being used on non-RPi5 systems.)
