Not tested on rock5A, so might not work, and I don't have rock5A either, cannot modify the code.

You can read the official guide to turn on the fan. Maybe, you can try this: https://forum.radxa.com/t/how-to-enable-fan-for-rock-5a/16834

This works for me. I can change the speed manually with echo 2 > /sys/class/thermal/cooling_device0/cur_state
