Description
A plea...
Deanna and I have been running this site since 2008 and lately we're seeing a big increase in
users (and cost) but a decline in percentage of users who donate. Our ad-free and junkware-free
download site only works if everyone chips in to offset the revenue that ads on other sites bring
in. Please donate at the bottom of the page. Every little bit helps. Thank you so much.
Sincerely,
your Older Geeks: Randy and Deanna

CoolerControl v4.3.1

👉 Monitor and control cooling devices, fan curves, RGB lighting, and system temperatures on Linux.

CoolerControl is a powerful Linux application for monitoring and managing your PC's cooling hardware from a single modern interface. It combines support for standard hardware monitoring with advanced fan and pump control, custom temperature sensors, RGB lighting management, dashboards, and automation profiles. CoolerControl works with many motherboard sensors, GPUs, AIO liquid coolers, and other supported devices through Linux hardware monitoring frameworks and supported back-end services.

The application provides real-time monitoring of temperatures, fan speeds, pump speeds, voltages, utilization, and other hardware statistics while allowing you to create custom fan curves based on multiple temperature sources. Built-in dashboards, profiles, and automation make it easy to optimize cooling for quiet operation, gaming, or maximum performance.




Features:
• Monitor CPU, GPU, motherboard, storage, and other hardware sensors
• Create custom fan and pump curves
• Control supported RGB lighting devices
• Build custom dashboards for system monitoring
• Create and switch between cooling profiles and modes
• Use multiple temperature sources for intelligent fan control
• Support custom sensors and calculated values
• View real-time graphs and historical statistics
• Configure alerts and advanced device settings
• Support supported liquid coolers, fan controllers, and motherboard sensors
• Automatic detection of supported hardware
• Modern desktop interface with dark theme support
• Includes both desktop application and background daemon

Supported operating systems:
• Arch Linux
• Debian 12 Bookworm or higher
• Fedora
• NixOS
• openSUSE Tumbleweed
• Ubuntu 22.04 or higher

Supported languages:
English

Installation:
This download includes the CoolerControl desktop application, daemon, AppImage, and distribution packages in a single ZIP archive.

For most users, install both the coolercontrold package (required) and the coolercontrol desktop application (optional but recommended). The daemon runs in the background and controls supported hardware, while the desktop application provides full desktop integration. You can also access the built-in web interface (http://localhost:11987/) from your browser if you choose not to install the desktop application. Optional packages such as liquidctl and lm_sensors can provide support for additional cooling devices and hardware sensors. Before creating fan profiles, verify that your hardware is detected and any required kernel modules are loaded.
