Jetson Fan Table Appears Incorrect

Environment
Device: Jetson NX orin CLB board 16GB
Jetpack: 6.0
L4T: 36.3.0
Kernel: 5.15.136-tegra

Problem Description
The fan tables in /etc/nvfancontrol.conf appear to be wrong.

In the documentation the example fan table appears as:

FAN_PROFILE cool {
        #TEMP   HYST    PWM     RPM
        0       0       255     2900
        10      0       255     2900
        11      0       215     2440
        30      0       215     2440
        60      0       66      750
        105     0       66      750
}

documentation link

But on my Jetson the profiles are:

  FAN_PROFILE quiet {
    #TEMP   HYST  PWM RPM
    0 0 255 6000
    10  0 255 6000
    11  0 187 4000
    31  0 187 4000
    70  0   0 0 
    105 0   0   0   
  }
  FAN_PROFILE cool {
    #TEMP   HYST  PWM RPM
    0 0 255 6000
    35  0 255 6000
    70  0   0 0 
    105 0   0   0   
  }

My Jetson is in a climate controlled room that is strictly controlled at 18C, so the device temperature is cooled a lot externally and the temps stay around 45C (as shown in jtop).

Question

  1. Is the fan table on my jetson incorrect?
  2. Should I use the sample nvfancontrol.conf file provided in the documents? Link here

Hi gavin28,

It seems to be correct as expected.
Please refer to Fan Profile Control for the document of R36.3.0. The link you shared is for R35.1.0.

You can also configure the /etc/nvfancontrol.conf for your use case.
