You can test your configuration first by running thinkfan manually (as root):Īnd see how it reacts to the load level of whatever other programs you have running. To use generic hwmon sensors instead of thinkpad-specific ones. Hwmon /sys/devices/virtual/thermal/thermal_zone0/temp Some systems have /proc/acpi/ibm/fan and /proc/acpi/ibm/thermal available on others, you will need to specify something like: This file specifies which sensors to read, and which interface to use to control the fan. To configure the temperature thresholds, you will need to copy the example configuration file ( /usr/share/doc/thinkfan/examples/thinkfan.yaml) to /etc/nf, and modify to taste. full-speed is the maximum unregulated speed. The thinkfan daemon will do this automatically. You should see that the fan level is "auto" by default, but you can echo a level command to the same file to control the fan speed manually: Note that the thinkfan package installs /usr/lib/modprobe.d/thinkpad_nf, which contains Optionally, but recommended, install lm_sensors. Install thinkfan AUR or thinkfan-git AUR. Some fan control daemons include simpfand-git AUR and thinkfan AUR (recommended). Make sure you have i8kmon properly set up beforehand, or leave the CPU idle while you test this program.īIOS fan control can be automatically disabled by starting/enabling rvice. Warning: Turning off BIOS fan control could result in damage to your hardware. The fan will switch back to low speed once the temperature drops to 65 ☌, and turns off completely at 45 ☌. This example starts the fan at low speed when the CPU temperature reaches 55 ☌, switching to high speed at 75 ☌. Look for a section similar to the following: Only three fans speeds are supported (high, low, and off). The temperature points at which the fan changes speed can be adjusted in the same configuration file. dell-bios-fan-control-git AUR - recommended if your BIOS overrides fan control.tk - must be installed together with tcl to run as X11 desktop applet.tcl - must be installed in order to run i8kmon as a background service (using the -daemon option).acpi - must be installed to use i8kmon.Additionally, you might want to install these: I8kutils AUR is the main package to control fan speed. Warning: i8kutils BIOS system calls stop the kernel for a moment on some systems (confirmed on Dell 9560), this can lead to side effects like audio dropouts, see Installation After that, run the following to check if it detected the sensors correctly:Ĭore 0: +29.0☌ (high = +76.0☌, crit = +100.0☌) This will detect all of the sensors present and they will be used for fancontrol. Check the official lm-sensors devices table to see if experimental drivers are available for such motherboards. Support for newer motherboards may not yet be in the Linux kernel. isw AUR - Fan configuration for some MSI laptops.įancontrol is a part of lm_sensors, which can be used to control the speed of CPU/case fans.fan2go-git AUR - An alternative to Fancontrol independent of device-paths.ASUS laptops - Configure some ASUS laptops for Fancontrol or manual control.ThinkPad laptops - Fan configuration for some ThinkPad laptops.Dell laptops - Alternative fan control daemon for some Dell laptops.Most suitable for latest, unsupported by Fancontrol laptops. NoteBook Fan Control (NBFC) - Cross-platform solution for laptop fan control, written in C# and works under Mono runtime.Most suitable for desktops and laptops, where fan controls are available via sysfs(5). Fancontrol (lm-sensors) - Script (written in Bash) to configure fan speeds.There are multiple working solutions for fan control for both desktops and notebooks. Here is some more information about this topic. In some cases, you will not be able to use the Fancontrol script due to incompatible cooling architecture (e.g. Some laptops have two fans for CPU and GPU, but the first fan cools down CPU and GPU at the same time, while the other one cools CPU only. Some laptops have single fan for both CPU and GPU and cools both at the same time. Note: Laptop users should be aware about how cooling system works in their hardware. 9.2.2 Alternative solution: absolute paths.9.2 Device paths have changed in /etc/fancontrol.9.1 Increase the fan divisor for sensors. 7.5 Fan control modes on certain TUF series laptops.7.3 Alternative method using EC registers.7.2 Generate configuration file with pwmconfig.2.4 Fancontrol stops working after suspend–wake cycles.
