The fan on my Jetson AGX ORIN developer kit never runs.
Could use some help troubleshooting what could be wrong.
The PWM is set to 255 according to Jetson Power GUI, but the fan never spins.

Hi pontus.brink,
What’s you Jetpack version in use?
Have you referred to the following instruction for fan control?
Jetson Orin NX Series and Jetson AGX Orin Series — Fan Profile Control
Or try to run the following command
$sudo systemctl stop nvfancontrol
$echo 255 > /sys/devices/platform/pwm-fan/hwmon/hwmon2/pwm1
I installed Jetpack version 5.1.1 (rev. 1) through SDK Manager.
$sudo systemctl stop nvfancontrol
$echo 255 > /sys/devices/platform/pwm-fan/hwmon/hwmon2/pwm1
Had no effect. I couldn’t echo to it due to permission denied but I sudo vim’d it.
Ill look through the docs you linked, the fan should be spinning according to the profile settings.
I ran the follow commands without effect on the fan:
sudo systemctl stop nvfancontrol
sudo vim /etc/nvfancontrol.conf (changed Kickstart PWM to 1) :x
sudo rm /var/lib/nvfancontrol/status
sudo systemctl start nvfancontrol
Here is the nvfancontrol.conf if that helps:

Could you try to run sudo su
before echo
?
nvfancontrol service would control the fan speed according to the current temperature, so you need to disable before control it directly.
Fan did not start with the following commands:
sudo su
systemctl stop nvfancontrol
echo 255 > /sys/devices/platform/pwm-fan/hwmon/hwmon2/pwm1
I’m closing this topic due to there is no update from you for a period, assuming this issue was resolved.
If still need the support, please open a new topic. Thanks
Is there any messages when you run these commands?
Please also provide the full serial console log for further check.
