LibreHardwareMonitor

Libre 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	Build Status
LibreHardwareMonitorLib Library that allows you to use all features in your own application
LibreHardwareMonitor.Windows.Forms Windows Forms based application that presents all data in a graphical interface
LibreHardwareMonitor.Avalonia Avalonia based application that presents all data in a graphical interface In development, not recommended yet

What can it do?

You can read information from devices such as:

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

Where can I download it?

You can download the latest release here.

Nightly builds

If you have a GitHub account, you can download nightly builds here.

Otherwise, you can download the latest nightly build here (Windows.Forms) or here (Avalonia).

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.

Developer information

Integrate the library in own application

1. Add the LibreHardwareMonitorLib NuGet package to your application.
2. Use the sample code below.

Sample code

Computer computer = new Computer
{
    IsCpuEnabled = true,
    IsGpuEnabled = true,
    IsMemoryEnabled = true,
    IsMotherboardEnabled = true,
    IsControllerEnabled = true,
    IsNetworkEnabled = true,
    IsStorageEnabled = true,
    IsPowerMonitorEnabled = true,
};

computer.Open();
computer.Accept(new UpdateVisitor());

foreach (IHardware hardware in computer.Hardware)
{
    Console.WriteLine("Hardware: {0}", hardware.Name);
    
    foreach (IHardware subhardware in hardware.SubHardware)
    {
        Console.WriteLine("\tSubhardware: {0}", subhardware.Name);
        
        foreach (ISensor sensor in subhardware.Sensors)
            Console.WriteLine("\t\tSensor: {0}, value: {1}", sensor.Name, sensor.Value);
    }

    foreach (ISensor sensor in hardware.Sensors)
        Console.WriteLine("\tSensor: {0}, value: {1}", sensor.Name, sensor.Value);
}

computer.Close();

public class UpdateVisitor : IVisitor
{
    public void VisitComputer(IComputer computer) => computer.Traverse(this);

    public void VisitHardware(IHardware hardware)
    {
        hardware.Update();
        foreach (IHardware subHardware in hardware.SubHardware)
            subHardware.Accept(this);
    }

    public void VisitSensor(ISensor sensor) { }

    public void VisitParameter(IParameter parameter) { }
}

Administrator rights

Some sensors require administrator privileges to access the data. Restart your IDE with admin privileges, or add an app.manifest file to your project with requestedExecutionLevel on requireAdministrator.
