LibreHardwareMonitor is a free software tool that monitors temperature sensors, fan speeds, voltages, load, and clock speeds of computer hardware components.
Libre Hardware Monitor is free software that can monitor the temperature sensors, fan speeds, voltages, load and clock speeds of your computer.
This tool is primarily used by system administrators, hardware enthusiasts, and developers to monitor and analyze the health and performance of computer hardware components in real-time. It provides detailed sensor data from CPUs, GPUs, motherboards, storage devices, and network cards, enabling proactive hardware management and troubleshooting.
The tool is Windows-focused and requires .NET Framework 4.7.2 or later; users should verify hardware compatibility as sensor reading methods may vary by manufacturer. Contributions to improve hardware support are welcomed via pull requests.
