If you don't have a system in place that manages fan spees, e.g. OpenBMC, fancontrol can bring various benefits to your system, such as quieter working system and power saving by reducing fan speeds on low CPU load.
Install and configure
sudo apt install 'lm-sensors fancontrol' && sudo sensors-detect && sudo -e '/etc/fancontrol' && sudo systemctl enable 'fancontrol'
Notes regarding changing hwmon paths
hwmon paths can change after rebooting a system. This results in different paths in /etc/fancontrol which renders the current setup useless and requires to manually reset /etc/fancontrol or running pwmconfig again on each reboot.
Thus it's recommended to create a .conf file in /etc/modprobe.d/ to set sensor module load order for reboot-stable fancontrol settings. After rebooting and fixing the paths in /etc/fancontrol or running pwmconfig.
For example on an ASUS KCMA-D8:
