I’m not sure that it is default config of Jetson Orin NX’s Fan.

hello zeju00,

may I know what’s the questions?
it looks the same fan control profiling table from Jetpack public release.

I checked the config because I got the device recently from my colleague but I’m not sure it is default setting for fan.

However you told me it is public release version. Thanks
