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