Can FAN turn on automatic?

i have an xavier nx, when i reboot, system auto run jetson_clocks, then the FAN turn on with 100% speed! even there is low LOAD,
then , how can i do to make the FAN turn on automatic??
please help!

hello jcyhcs,

are you having --fan options to enable jetson_clocks?
since jetson_clocks no longer sets maximum fan speed by default starting with L4T release 32.4.

every fan speed step is associated with the trip point temperature and corresponding hysteresis.
