Pwm-fan default mode

[kcs]

hello, teams

I use custom carrier board, AGX ORIN rel36-4.

I have a question about the “pwm-fan” operation mode.

Which is the default mode of operation, running full power regardless of temperature of the module or sensing the temperature of the module?

I looked up the document below. I think the default mode of operation seems to detect temperature. Is that correct?

Thanks.

Hi kcs,

@kcs

Correct.
It is handled by nvfancontrol.service which will control the FAN speed according to the temperature.
You can refer to that doc in your link or /etc/nvfancontrol.conf on your board.
