Fan Strategy

AIBOX-1684X fan operation is divided into 4 levels:

Main control current temperature	Fan operating level
≥40℃	1
≥55℃	2
≥65℃	3
≥85℃	4

Warning

As the temperature of the device box rises, the temperature level will also automatically increase synchronously.

Check CPU temperature:

    cat /sys/class/thermal/thermal_zone0/temp

Check the temperature of the development board:

    cat /sys/class/thermal/thermal_zone1/temp

Check fan rating:

    cat /sys/class/thermal/cooling_device0/cur_state

Check the maximum fan level:

    cat /sys/class/thermal/cooling_device0/max_state

To modify the fan level:

    echo 1 > /sys/class/thermal/cooling_device0/cur_state
