Get SSD temperature in .NET

Question

EDIT: Apparently Asus Strix X570 (my motherboard) does not have WMI interface so it has to be a non-WMI solution

I found this: How to read HardDisk Temperature?

However in 4.8 this throws exception (ran it as administrator): Not supported

var searcher = new ManagementObjectSearcher(
    "root\\WMI", "SELECT * FROM MSStorageDriver_ATAPISmartData");
foreach (ManagementObject queryObj in searcher.Get())

Also tried queries and got same exception:

SELECT * FROM MSStorageDriver_FailurePredictStatus
Select * from MSStorageDriver_FailurePredictData
Select * from MSStorageDriver_FailurePredictThresholds

Exception:

I need to measure M.2 SSD temperature on my machine.

The temperature is visible in the Windows Storage settings:

Also all SMART sensors visible on HWiNFO tool ran without administrator privilege:

Are you running this as admin? Please show your full code and the full exception message, *as text* — Charlieface, Nov 22 '21 at 14:55
yes - ran as admin - see the question. exception is on the picture - there is no information except "Not supported". It fails on `searcher.Get()` - see the code I added. — Boppity Bop, Nov 22 '21 at 15:13
You might want to look into using [LibreHardwareMonitor](https://github.com/LibreHardwareMonitor/LibreHardwareMonitor). HDDs/SSDs has vendor specific ways of storing sensor data. — Hank, Nov 22 '21 at 16:22
good call.. i was looking at OpenHardwareMonitor which has nothing for NVMe drives. And Libre works! make it an answer Ill mark it thanks! — Boppity Bop, Nov 22 '21 at 16:57

Got LibreHardwareMonitor. Implemented class like this:

public class TempSensor
{
    Timer timer;
    private Computer computer;
    UpdateVisitor visitor;
    int interval;

    public event EventHandler<EventArgs2<float?,float?>> Ticked;

    public void Start(int interval = 1000)
    {
        this.interval = interval;

        visitor = new UpdateVisitor();

        computer = new Computer();

        computer.HardwareAdded += HardwareAdded;

        computer.Open();

        computer.IsCpuEnabled = true;
        computer.IsStorageEnabled = true;

        timer = new Timer(OnTimer);
        timer.Change(100, interval);
    }

    void OnTimer(object o)
    {
        computer.Accept(visitor);

        IList<ISensor> list = new List<ISensor>();
        SensorVisitor vis = new SensorVisitor(i => { list.Add(i); });

        vis.VisitComputer(computer);
            
        var sensors = list.Where(i => i.SensorType == SensorType.Temperature).ToList();
        var cpu = sensors.FirstOrDefault(i => i.Hardware.HardwareType == HardwareType.Cpu);
        var disk = sensors.FirstOrDefault(i => i.Hardware.HardwareType == HardwareType.Storage);

        if (Ticked != null)
            Ticked(this, new EventArgs2<float?,float?>(cpu?.Value, disk?.Value));

        timer.Change(interval, interval);
    }

    private void HardwareAdded(IHardware hardware)
    {
        foreach (ISensor sensor in hardware.Sensors)
            SensorAdded(sensor);

        hardware.SensorAdded += SensorAdded;

        foreach (IHardware subHardware in hardware.SubHardware)
            HardwareAdded(subHardware);
    }

    private void SensorAdded(ISensor sensor)
    {
    }
}

use like this:

sensor = new TempSensor();
sensor.Ticked += Sensor_Ticked;
sensor.Start(3019);
