LibreHardwareMonitor

Libre Hardware Monitor, a fork of Open Hardware Monitor, is free software that can monitor the temperature sensors, fan speeds, voltages, load and clock speeds of your computer.

What's included?

Name	.NET	Build Status
LibreHardwareMonitor Windows Forms based application that presents all data in a graphical interface	.NET Framework 4.5.2
LibreHardwareMonitorLib Library that allows you to use all features in your own application	.NET Framework 4.5.2, .NET Standard 2.0, .NET 5.0.0

What can you do?

With the help of LibreHardwareMonitor you can read information from devices such as:

• Motherboards
• Intel and AMD processors
• NVIDIA and AMD graphics cards
• HDD, SSD and NVMe hard drives
• Network cards

Where can I download it?

You can download the latest release here.
If you're signed in to GitHub, you can also download the latest builds here. Click on a result and download Binaries under Artifacts.

How can I help improve it?

The LibreHardwareMonitor team welcomes feedback and contributions!
You can check if it works properly on your motherboard. For many manufacturers, the way of reading data differs a bit, so if you notice any inaccuracies, please send us a pull request. If you have any suggestions or improvements, don't hesitate to create an issue.

What's the easiest way to start?

LibreHardwareMonitor application:

1. Download the repository and compile 'LibreHardwareMonitor'.
2. You can start the application immediately.

Sample code:

1. Download the repository and compile 'LibreHardwareMonitorLib'.
2. Add references to 'LibreHardwareMonitorLib.dll' and 'HidSharp.dll' in your project.
3. In your main file, add namespace 'using LibreHardwareMonitor.Hardware;'
4. Now you can read most of the data from your devices.
