FANCONTROL
Section: 8Misc. Reference Manual Pages (8) NAME
fancontrol - automated software based fan speed regulation SYNOPSIS
fancontrol [configfile] DESCRIPTION
fancontrol is a shell script for use with lm_sensors. It reads its configuration from a file, then calculates fan speeds from temperatures and sets the corresponding PWM outputs to the computed values. WARNING
Please be careful when using the fan control features of your mainboard, in addition to the risk of burning your CPU, at higher temperatures there will be a higher wearout of your other hardware components, too. So if you plan to use these components in 50 years, maybe you shouldn't use fancontrol at all. Also please keep in mind most fans aren't designed to be powered by a PWMed voltage. In practice it doesn't seem to be a major issue, the fans will get slightly warmer, just be sure to have a temperature alarm and/or shutdown call, in case some fan fails, because you probably won't hear it anymore ;) CONFIGURATION
For easy configuration, there's a script named pwmconfig(8) which lets you interactively write your configuration file for fancontrol. Alternatively you can write this file yourself using the information from this manpage. Since most of you are going to use pwmconfig(8) script, the config file syntax will be discussed last. First I'm going to describe the various variables available for changing fancontrol's behaviour: INTERVAL This variable defines at which interval in seconds the main loop of fancontrol will be executed FCTEMPS 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. FCFANS FCFANS records the association between a PWM and a fan. Then fancontrol can check the fan speed and restart it if it stops unexpectedly. MINTEMP The temperature below which the fan gets switched off completely. MAXTEMP The temperature over which the fan gets switched to full speed. MINSTART Sets the minimum speed at which the fan begins spinning. You should use a safe value to be sure it works, even when the fan gets old. MINSTOP The minimum speed at which the fan still spins. Use a safe value here, too. If you set up your configuration by hand, be sure to include ALL variables and use valid values, there's no error handling yet! The file format is a bit strange: VARIABLE=chip/pwmdev=value chip/pwmdev2=value2
VARIABLE2=...
Each variable has its own line. The variable name is followed by an equal sign and the device=value pairs. These consist of the relative path to the pwm output (from /proc/sys/dev/sensors/) for which the value is valid, equal sign followed by the value and are seperated by a blank. Example: MINTEMP=w83627hf-isa-0290/pwm2=40 w83627hf-isa-0290/pwm1=54 You have to play with the temperature values a bit to get happy. For initial setup I recommend using the pwmconfig script. Small changes can be made by editing the config file directly following the rules above. THE ALGORITHM
fancontrol first reads its configuration, writes it to arrays and loops its main function. This function gets the temperatures and fanspeeds from lm_sensors proc files and calculates new speeds depending on temperature changes, but only if the temp is between MINTEMP and MAXTEMP. After that, the new values are written to the PWM outputs. Currently the speed increases quadratically with rising temperature. This way you won't hear your fans most of the time at best.

PWMCONFIG
Section: 8Misc. Reference Manual Pages (8) NAME
pwmconfig - tests the PWM outputs of sensors and configures fancontrol SYNOPSIS
pwmconfig DESCRIPTION
pwmconfig searches your sensors for pulse width modulation (PWM) controls, and test each one to see if it controls a fan on your motherboard. Note that many motherboards do not have PWM circuitry installed, even if your sensor chip supports PWM. It attempts to briefly stop each fan using the PWM controls. It then attempts to restore each fan to full speed after testing. However, it is very important that you physically verify that the fans have been returned to full speed after the program has completed. WARNING
This program will stop your fans, one at a time, for approximately 5 seconds each. This may cause your processor temperature to rise. Verify that all fans are running at normal speed after this program has exited. CONFORMING TO

A priori, ca fait partie du package lm_sensors, en tout cas pour la Mandrake Cooker avec laquelle je fais mumuse là
Pour la Gentoo aussi, apparamment
Bon, je vais tester maintenant
Je décline toute responsabilité quant au mauvais usage qui pourrais être fait de tout ça
