Libre Hardware Monitor
What Libre Hardware Monitor is
Libre Hardware Monitor is free, open-source software for viewing computer sensor data on Windows. It monitors temperatures, fan speeds, voltages, load, and clock speeds, with remote monitoring supported. The project says it can read information from motherboards, Intel and AMD processors, NVIDIA, AMD and Intel graphics cards, HDD, SSD and NVMe drives, and network cards. Its Windows Forms desktop application presents readings in a graphical interface. Developers can use LibreHardwareMonitorLib in another application; the project README describes adding the library through NuGet. A sample demonstrates enabling CPU, GPU, memory, motherboard, controller, network, storage, and power monitor data, then reading sensor values. The app lists .NET Framework 4.7.2 and .NET 10.0, while the library lists .NET Framework 4.7.2, .NET Standard 2.0, and .NET 8.0, 9.0, and 10.0. Downloads include latest releases and nightly builds. Some sensors require administrator privileges, and hardware manufacturers may affect reading accuracy.
