Open Source C Fan Control Software

Lenovo Legion Linux (LLL) brings additional drivers and tools for Lenovo Legion series laptops to Linux. It is the alternative to Lenovo Vantage or Legion Zone (both Windows only). It allows you to control features like the fan curve, power mode, power limits, rapid charging, and more. This has been achieved through reverse engineering and disassembling the ACPI firmware, as well as the firmware and memory of the embedded controller (EC).

mbpfan is a lightweight daemon for Linux that provides fan speed management for MacBook and MacBook Pro hardware. It reads temperature data via the coretemp kernel module and drives fan speeds through the applesmc interface, making it especially valuable for users running Linux natively on Apple hardware where automatic thermal control may be lacking. The daemon supports multiple processors and multiple fans, allowing flexible configurations for complex Mac models, and aims to keep systems both cool and quiet by dynamically adjusting fan behavior. While originally based on Allan McRae’s mbpfan, this enhanced version expands compatibility and tuning options. It’s especially useful on Linux installations where default drivers don’t effectively communicate with Apple’s proprietary sensor and fan hardware. Users often pair it with custom configuration profiles to match their preferred balance of noise and temperature control.

A simple fan control program. Read temperatures, check them against configured limits and switch to appropriate (also pre-configured) fan level. Requires a working thinkpad_acpi or any other hwmon driver that enables temperature reading and fan control from userspace.

TuxClocker is an open-source Qt-based overclocking and hardware monitoring utility tailored for GNU/Linux systems. The project combines a DBus daemon with a Qt graphical user interface, allowing users to inspect and adjust performance characteristics of their hardware—particularly GPUs—under Linux. TuxClocker provides a user-friendly GUI atop lower-level interfaces, making it easier to control clock speeds, fan behavior, and other tuning parameters without resorting exclusively to command-line tools. It is especially useful for Linux enthusiasts and power users looking to optimize performance for gaming, content creation, or benchmarking. The project also has a companion command-line version (tuxclocker-cli), broadening usability scenarios for scripting or headless setups. While the features and hardware support may vary by distribution and driver stack, TuxClocker fills a niche for integrated Linux performance tuning with a polished front end.

HWSensors is a software bundle that includes drivers and applications that allow you to access information from hardware sensors available on your Mac. FakeSMC is an open source SMC device driver/emulator developed by netkas (http://netkas.org/). NOTE: FakeSMC & Plugins starting from v915 provide additional sensors information to HWMonitor then running on Macs. By installing FakeSMC on real Mac you should consider you know what you are doing and how to recover your system if something will goes wrong.

Thinkpad fan control : Controls IBM / Lenovo Thinkpad computer's fan according to user defined temperatures.

This is a Linux driver for ThinkPad laptops, written by Borislav Deianov and Henrique de Moraes Holschuh. It aims to support various features of these laptops which are accessible through a ThinkPad-specific ACPI framework. The newest version is available in the latest version of the Linux kernel.

These tools aim to Toshiba-Laptop users, who want to use their extra keys to control the brightness of the LCD or to control the fan. It even lets you use the extra multimediakeys on the newer Laptops to control xmms, a dvd-player software, etc.

autofan is a very simple and light daemon written in C that automatically controls fan speed, according to GPU/board temperature, on an Nvidia-card that doesn't support automatic hardware control. It builds ontop of the nvclock backend.

cooling home automation with Arduino(C) and Raspberry(front-end, python). Arduino features: - control PC 4-pin fan with PWM; - measure temperature/humidity with DHT11/22; - adjust fan RPM depend on temperature; - console management; - MQTT serial output. front-end features: - data collection form serial port with MQTT - webUI with for sensors parameters

A daemon to automatically control the fan speed of Thinkpad laptops using the ThinkPad ACPI Extras Driver in order to minimize noise pollution and extend battery life.
