Thinkpad Fan Control

From the Thinkpad Fan Control website:

tp-fan monitors temperatures and controls fan speed of IBM/Lenovo ThinkPad notebooks. tp-fan is an open-source project released under the GPL v3.
The tpfand daemon controls the system fan in software. It can be used to make the notebook more quiet. However this will also result in higher system temperatures that may damage and/or shorten the lifespan of the computer. Since version 0.90 fan trigger temperatures can be configured separately for each temperature sensor.
This project also provides the tpfan-admin GTK+ frontend to monitor system temperature and adjust fan trigger temperatures.
Warning: This program may damage your notebook. The author does not take any responsibility for damages caused by the use of this program.

Installation

tpfand

Note: tpfand is not actively developed anymore! There's a fork called tpfanco (see below).

The tpfandAUR[broken link: archived in aur-mirror] daemon can be installed from the AUR. Alternatively, a version that doesn't require HAL is also available from the AUR: tpfand-no-halAUR[broken link: archived in aur-mirror]

An additional GTK+ frontend is provided in the tpfan-adminAUR[broken link: archived in aur-mirror] package in the AUR which enables the monitoring of temperatures as well as the graphical adjustment of trigger points.

tpfanco

Due to tpfand not beeing actively developed anymore, there's a fork called tpfanco (which in fact uses the same names for the executables as tpfand): tpfanco-svnAUR[broken link: archived in aur-mirror]. It may be used as a complete replacement for tpfand.

Configuration

The configuration file for tpfand (same for tpfanco) is found in /etc/tpfand.conf. This file can be edited to adjust the fan trigger points to suit your needs.

Additionally, the tpfand-profilesAUR[broken link: archived in aur-mirror] package in the AUR gives the latest fan profiles for various thinkpad models.

Running

The tpfand daemon can be started by running (as root):

# systemctl start tpfand

or by automatically loading it on system startup:

# systemctl enable tpfand
