Fan Settings in Ubuntu Server?

VIM4
1

Which system do you use? Android, Ubuntu, OOWOW or others?

Ubuntu Server / Ubuntu Desktop 22

Which version of system do you use? Khadas official images, self built images, or others?

Self-Built via Fenix

Please describe your issue below:

I have the VIM4 active cooling kit.

When using Ubuntu Desktop I can just use the Fan Settings app to set the fan control.
Is there a way I can change fan settings (Temps/Speed) when using Ubuntu Server?

Reason I ask is that the fan seems to just randomly spin up and then off no matter what the device is doing (sitting idle or actually doing something)

Post a console log of your issue below:

The documentation or the fan.sh could use some review:

user@Khadas:~$ fan.sh level
Error: Fan mode/level is unknown!

This parammeter not available, you can use fan.sh mode, we will update the documentation.

Hello all,
Do you have a plan about fan control at Android OS?
If possible, I would like to be able to read the CPU temperature as well.

Hello @Jeter

For Android, just goto the system settings to setup the FAN.

Oh, ‘The system setting to setup the FAN’ is Ksettings, cooling fan?
Off// Automatic speed control// Level 1,2,3
I want to more information
Current temperature, Trigger low/mid/high temp, and so on

Please goto folder /sys/class/fan to check the node.

$ ls /sys/class/fan
enable  mode  trigger_temp_high  trigger_temp_mid
level   temp  trigger_temp_low
