Radxa Zero 2 Pro Fan in Radxa OS

We’re using the Radxa OS (Debian linux). We want to connect a FAN to the FAN connector. Does anyone know how it is managed by Radxa OS? Is it automatically turned ON by the OS above a certain temperature? Or do we need to turn it ON and OFF programmatically? and how?
Thanks

you can use radxa utils rsetup to manage fan.
