Jetson Orin NX FanMode Setting

April 9, 2024, 12:13 a.m.

Jetson Orin's Defaut Fan mode is quite. And I ran some Deep Learning models, Orin easliy getting throttled.

So I want to make Fan faster,,,, This is how I change the fan mode setting.

.

Stop the nvfancontrol service

sudo systemctl stop nvfancontrol

.

Change the config file

vim /etc/nvfancontrol.conf

POLLING_INTERVAL 2
<FAN 1>
    TMARGIN ENABLED
    FAN_GOVERNOR pid {
            STEP_SIZE 10
    }
    FAN_GOVERNOR cont {
            STEP_SIZE 10
    }
    FAN_CONTROL close_loop {
            RPM_TOLERANCE 100
    }
    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
    }
    FAN_PROFILE quiet {
            #TEMP   HYST    PWM     RPM
            0       0       255     2900
            10      0       255     2900
            11      0       171     1940
            23      0       171     1940
            60      0       66      750
            105     0       66      750
    }
    THERMAL_GROUP 0 {
            GROUP_MAX_TEMP 105
            #Thermal-Zone Coeffs Max-Temp
            CPU-therm 20,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 0
            GPU-therm 20,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 0
            SOC0-therm 20,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 0
            SOC1-therm 20,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 0
            SOC2-therm 20,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 0
    }
    FAN_DEFAULT_CONTROL close_loop
    FAN_DEFAULT_PROFILE cool
    FAN_DEFAULT_GOVERNOR cont
    KICKSRART_PWM 64

You should change FAN_DEFAULT_PROFILE as cool

.

Run the nvfancontrol again.

sudo systemcontrol start nvfancontrol
