Fan speed on AGX Orin

Devkit board Fan can correctly identify the speed,but Custom board fan can not correctly identify the speed.
Can you help to provide the information about the speed of the Devkit board Fan,Thanks

Hi sorry.shao,

What’s your Jetpack version in use?

Could you share result of the following command on your board?

$ ls -l /sys/class/hwmon/

Do you have any custom design for the fan different from the devkit?


For the fan from the devkit, the rpm is 2900 ± 10% R.P.M..
How about yours?

Have you tried using the fan from devkit on your custom carrier board and it could work?

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.

Is this still an issue to support? Any result can be shared? Thanks
