thinkfan is described as 'Thinkfan is a simple, lightweight fan control program. Originally designed specifically for IBM/Lenovo Thinkpads, it now supports any kind of system via the sysfs hwmon interface (/sys/class/hwmon). It is designed to eat as little CPU power as possible' and is an app. There are more than 10 alternatives to thinkfan for Windows, Linux, Mac and Flathub. The best thinkfan alternative is SpeedFan, which is free. Other great apps like thinkfan are CoreCtrl, Macs Fan Control, fan-control and Lm-Sensors.

CoreCtrl is a Free and Open Source GNU/Linux application that allows you to control with ease your computer hardware using application profiles.

Monitor and control fans on Apple computers with a simple and efficient user interface




Lm-Sensors is a free and open-source application that provides tools and drivers for monitoring temperatures, voltage, and fans.

Solution to the cooling fan noise annoyances Thinkpad T4x (T40/T41/T42/T43) notebook series. Allows the user to control fan activity based on the system temperature. Win XP Visual C++ project controls the fan via port IO to the embedded controller.

This software detects and optionally controls speed of CPU fan of many PC-Systems. Furthermore you are able to configure the handling of the EC-registers on your own (risk). To determine the EC-registers use e.g. software like "rw everything".



smcFanControl is the perfect application for all those Macbook owners getting burned by their hot-running Macbook.

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.
