My nx application does not require an external fan, how can I disable this log output.

Hi 924908681,

Are you using the devkit or custom board for Xavier NX?
What’s your Jetpack version in use?

@924908681

how can I disable this log output.

Could you try the following command to disable nvfanctrol service?

$ systemctl stop nvfancontrol
