I tried your program on my rock 5a and it doesn't work
is there anything to activate it?

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

Otherwise, i'll try the official method

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