In Linux 2.6.22 and higher you need to additionally pass fan_control=1 to the module thinkpad_acpi (e.g., # modprobe thinkpad-acpi experimental=1 fan_control=1) On Ubuntu > 10.04 or from kernel 2.6.32 onwards: To make the kernel module settings permanent and to make them be executed at boot run below command and reboot afterwards: I'm pretty new to Linux so I … Source and binaries are available through the "Tp4xFanControl" project on SourceForge.. IbmPad's IBM_ECW fan control program can also be used, but it … I configured my fan to only start when the computer is warmer than 55oC, greatly improving the noise. The first line of the sensors output is the chipset used by the motherboard for readings of temperatures and voltages. Some of the cpu temperature and fan control register may be exposed to the ec. We will attempt to briefly stop each fan using the pwm controls. if linux is such a great alternative to windows, why can't it have cpu fan control without user fiddling, like windows? 33000 for 33°C. Name: gpio-fan Info: Configure a GPIO pin to control a cooling fan. Now to run fan control, type: sudo /usr/sbin/fancontrol &. If the BIOS fan control is in place, you can try using dell-bios-fan-control-gitAUR: To automatically disable BIOS fan control via systemd: Current fan control daemons available in the AUR are simpfand-gitAUR and thinkfanAUR (recommended). Look at #Device Paths have Changed in /etc/fancontrol for more information. I have Dell Inspiron 7559 with i7 cpu. Check the fans you want it to control. If you do not see the /hwmon/hwmon#/ directory, then you do not have to worry about this. Thank you for creating this. Check if you have any controls over your fan: If you were able to modify fan speed with above commands, then continue with #Generate config file with pwmconfig. Just replace hwmon#/ with the absolute file path. And level 2, which is the highest level for thermal control and comes with the fastest fan speed. Fancontrol is a generic fan control script provided by package sys-apps/lm-sensors which can run as a system daemon. This means that the temperature files are in the root of the device folder. These get loaded in by fancontrol. After that, the new values In x86 type of systems the speed of the fans is typically controlled by the BIOS, but it may be possible to control the fan speed with the linux kernel and userspace utilities. On Arch Linux (or Manjaro Linux) there are some tools that can help with that. asus_fan is a kernel module, which allows to control both fans on some older Asus laptops.

So I’m basically done. Configure sensors by running sudo sensors-detect command. It will only allow to control a single fan and if there is a second fan - you will not have any controls over it. If your hwmon paths keep changing, this will prevent fancontrol from running no matter what you do. First a word of warning: CoreCtrl will immediately override your current fan, CPU and GPU settings when you first launch it. Only three fans speeds are supported (high, low, and off). You can find them in /opt/nbfc/Configs/ directory. Introduction In Windows I controlled the fanspeed on my stationary computer by using a ASUS program that read the temperatures. It may also be required to restart the script via a root-resume.service after hibernation in order to make it automatically function properly again: If sensors does not output the CPU fan RPM, it may be necessary to change the fan divisor. by editing the config file directly following the rules above. Fancontrol (lm-sensors) is written in Bash, so using these paths in configuration file is completely acceptable. GitHub Page. Currently the speed increases quadratically with rising temperature. Too hot is not good for the electronics of a computer. Also start and enable nbfc.service. It uses a "speed-matrix" to match the frequency of the fans with the temperature of the GPU, for example: Once the package is installed, it can be run as a service, so you can either run it for the current session: Not just fan controls are offered via hwmon in sysfs, but also GPU temperature reading: This outputs GPU temperature in °C + three zeroes, e.g. The enumerated hwmon symlinks located in /sys/class/hwmon/ might vary in order because the kernel modules do not load in a consistent order per boot. Users should hear system fans starting shortly after executing this command. This way you won’t hear your fans mostof the time at best. fancontrolfirst reads its configuration, writes it to arrays and loops its main function. YMMV! asus-nb-wmi is a kernel module, which is included in the Linux kernel and is loaded automatically on Asus laptops.

Currently the speed increasesquadratically with rising temperature. Blacklisting this module will prevent keyboard backlight to work. Additionally, you might want to install these: By default, i8kmon only monitors the CPU temperature and fan speed passively. Were you using a fan control utility in Windows 7? trip_point_index: The active cooling trip point number that corresponds to this performance state (0-9). This function gets the temperatures and fanspeeds fromkernel driver files and calculates new speeds depending on temperature changes, but only if the temp is between MINTEMP and MAXTEMP. I wanted the same temperature/fanspeed scaling in Linux, so I decided to setup fancontrol, which is a small script that monitors temperatures and fanspeeds and sets the fan at the minimum required level to insure low noise levels. It also allows to comfortably adjust the fancurve's temperature/PWM cycles assignments and a hysteresis by offering abstracted configuration fields at the top of the script. Check the official lm-sensors devices table to see if experimental drivers are available for such motherboards. Solution to the cooling fan noise annoyances Thinkpad T4x (T40/T41/T42/T43) notebook series.
