MINSTART Sets the minimum speed at which the fan begins spinning. MAXTEMP The temperature over which the fan gets switched to maximum speed. MINTEMP The temperature below which the fan gets switched to minimum speed. Then fancontrol can check the fan speed and restart it if it stops unexpectedly. This lets fancontrol check that the configuration file is still up-to-date.įCTEMPS Maps PWM outputs to temperature sensors so fancontrol knows which temperature sensors should be used for calculation of new values for the corresponding PWM outputs.įCFANS Records the association between a PWM output and a fan input. This lets fancontrol check that the configuration file is still up-to-date.ĭEVNAME Records hwmon class device names. INTERVAL This variable defines at which interval in seconds the main loop of fancontrol will be executedĭEVPATH Maps hwmon class devices to physical devices. First I'm going to describe the various variables available for changing fancontrol's behaviour: Since most of you are going to use pwmconfig(8) script, the config file syntax will be discussed last. Alternatively you can write this file yourself using the information from this manpage. For easy configuration, there's a script named pwmconfig(8) which lets you interactively write your configuration file for fancontrol.
