No Xavier fan on Jetpack 5.0.1

After flash AGX Xavier to Jetpack 5.0.1. No fan was found in /sys/device. At the same time, “Jetson Power GUI” show no fan. However, every time I reboot the Xavier, the fan will work for a while.

Please check if any connection issue on your device.

hello live459745355,

did you meant the fan only rotate during the system boot-up? it’s normal due to the default settings.

the fan speed step is associated with the trip point temperature.
please check the configuration file, i.e. /etc/nvpmodel/nvpmodel_t194.conf, and changing the default fan mode.
here’s documentation for your reference, Fan Mode Configuration.
thanks

Hi,

In the case of Jetpack 5.0.1, the fan is controlled by the files of /etc/nvpower/nvfancontrol folder? Xavier case, edit the file ‘nvfancontrol_p2888.conf’ the parameter FAN_DEFAULT_PROFILE from quiet to cool, for example.

hello k-hamada,

yes, nvfancontrol is a userspace fan speed control daemon used by Orin.
you may configure the default fan profile by… /etc/nvfancontrol.conf.

Do you make a distinction between daemon and the config file for it?

hello k-hamada,

may I know what’s the failure you seen, we’ve tested it and nvfancontrol work normally.

may I know what’s the failure you seen

What do you want to say?

please check the configuration file, i.e. /etc/nvpmodel/nvpmodel_t194.conf, and changing the default fan mode.

Did you check it with Jetpack 5.0.1 ?

we’ve tested it and nvfancontrol work normally.

My Xavier fan is working fine on Jetpack 5.0.1 with the method as described above.
