How to set the fan to start automatically after NX is powered on? (JetPack 4.6)

,

I can set the fan to start automatically by using jtop In JetPack 4.4,However, on the jetpack 4.6 of jtop, the fan’s settings option has been removed.
Although I can set the fan speed by following the following command:
“sh -c ‘echo 153 > /sys/devices/pwm-fan/target_pwm’”
Oddly enough, if you put it in etc/rc.local, it doesn’t work when you boot it up.
Is there a method to set the fan to start automatically after NX is powered on with JetPack4.6?

hello blstcvLiu,

it’s now depends-on the thermal condition to on/off fan, the fan speed step is associated with the trip point temperature, it turns-off the fan when the temperature below 32°C.
you may also refer to Fan Mode Control and configure the fan operation as “cool” for verification.
thanks
