In my case the CPU temperature sensor coretemp-isa-0000 was named at hwmon1 in fancontrol, so I took hwmon1/temp1_input to correlate the fanspeed to the temperature.

I ran sensors in another shellsession to help me find the right sensor. This is a bit tricky as the sensor is named differently in fancontrol and lm-sensors. For the CPU fan make sure to use a sensor that measures your core CPU temperature to base the fan speed on. You will have to specify what sensors to use to link the fanspeed to temperature changes.

If that doesn't work, look at the last 3 sources at the bottom of this post. If you get an error /usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed, first try to reboot your machine (that solved it for me). For me only one channel was found as the case fans do not use PWM. This script will stop each fan for a few seconds to find out which fans can be controlled by which PWM handle.

This will read the changes you made to /etc/modules in the previous step, and insert the new modules into the kernel. Type yes or y to have sensors-detect insert those modules into /etc/modules. I read that it might give problems if non-existing sensors are being read.Īt the end of sensors-detect, a list of modules that need to be loaded will be displayed. Be careful if you have a different mainboard. apt update & apt install lm-sensors fancontrolĬonfigure lm-sensors as follows: sensors-detectĪnswer YES ( y) to all YES/no questions. Install the lm-sensors and fancontrol packages. Open a shellsession session to the server and login. On Ubuntu/Debian (Proxmox) this can be achieved by installing the lm-sensors package to read the CPU temperature data and fancontrol to control the fan speeds. This makes the CPU temperatures rise unnecessarily high, but can be fixed by letting the OS control the fan speed instead of the mainboard. However, the fan on the Artic Freezer i32 CPU cooler I installed doesn't rotate when the mainboard (BIOS) decides the fan speed should be 'low' (' a PWM fan that starts up at a higher load (40% PWM)'). This works perfectly with the case fans I installed in the front of the chassis. The Supermicro X9SCM mainboard used in my first server has 4 PWM fan connections that are normally controlled through the BIOS.
