Apply your changes by restarting the fancontrol service.It's designed to provide fan control for PWM fans that have 4 pins.Ī 3pin fan has connectors for power, common (ground), and RPM reporting (tachometer). Optionally you can make adjustments to fine-tune /etc/fancontrol, but I took all the default values. Now run through the prompts and save the changes to the default location. 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, add nct6775 to /etc/modules. If you get an error /usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed, first try to reboot your machine. 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.
sudo apt update & sudo apt install lm-sensors fancontrolĬonfigure lm-sensors as follows: sudo 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.
