Quadratically with rising temperature.Ok, so this is a work in progress, and it will take lots more time to complete. New values are written to the PWM outputs.
#Mint 18.3 config fancontrol driver#
Kernel driver files and calculates new speeds depending on temperatureĬhanges, but only if the temp is between MINTEMP and MAXTEMP. This function gets the temperatures and fanspeeds from The assumption that the configuration file may be out-of-sync with theįancontrol first reads its configuration, writes it to arrays and loops its Upon starting, fancontrol will make sure that all referenced devicesĭo exist and match what they were at configuration time, and that all Small changes can be made byĮditing the config file directly following the rules above. Setup I recommend using the pwmconfig script. You have to play with the temperature values a bit to get happy. Example: MINTEMP=hwmon0/device/pwm1=40 hwmon0/device/pwm2=54 sys/class/hwmon depending on the kernel version). Path can be absolute or relative (from /sys/bus/i2c/devices or Which the value is valid, equal sign followed by the value and are separatedīy a blank. These consist of the path to the pwm output for The variable name is followed by an equal signĪnd the device=value pairs. The configuration file format is a bit strange: VARIABLE=chip/pwmdev=value chip/pwmdev2=value2Įach variable has its own line. If this value isn't defined, it defaults to 255 (full speed). MAXPWM The PWM value to use when the temperature is over MAXTEMP. If this value isn't defined, it defaults to 0 (stopped fan). Stop, or the same value as MINSTOP if you don't want the fan to Typically, this will be either 0 if it is OK for the fan to plain MINPWM The PWM value to use when the temperature is below MINTEMP. MINSTOP The minimum speed at which the fan still spins. Use a safe value to be sure it works, even when the fan gets old. 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 FCFANS Records the association between a PWM output and a fan input. Temperature sensors should be used for calculation of new values for FCTEMPS Maps PWM outputs to temperature sensors so fancontrol knows which
The configuration file is still up-to-date. DEVNAME Records hwmon class device names. This lets fancontrolĬheck that the configuration file is still up-to-date. INTERVAL This variable defines at which interval in seconds the main loop ofįancontrol will be executed DEVPATH Maps hwmon class devices to physical devices. Variables available for changing fancontrol's behaviour: Since most of you are going to use pwmconfig(8) script, the configįile syntax will be discussed last. Alternatively you can write thisįile yourself using the information from this manpage. Named pwmconfig(8) which lets you interactively write yourĬonfiguration file for fancontrol. Some fan fails, because you probably won't hear it anymore )ĬONFIGURATIONFor easy configuration, there's a script
Warmer, just be sure to have a temperature alarm and/or shutdown call, in case In practice it doesn't seem to be a major issue, the fans will get slightly Also please keep in mind most fans aren't designed to be These components in 50 years, maybe you shouldn't use fancontrolĪt all. WARNINGPlease be careful when using the fan control features of your mainboard, inĪddition to the risk of burning your CPU, at higher temperatures there will beĪ higher wearout of your other hardware components, too. Sets the corresponding PWM outputs to the computed values. It reads itsĬonfiguration from a file, then calculates fan speeds from temperatures and
