How to Get HardWare Information from CPU like TemparatureVoltageFanSpeed. code in .Net

Question

I was using This Code...
//---Code---//

ManagementObjectSearcher mySearcher = new ManagementObjectSearcher("root\\WMI","SELECT * from Win32_TemparatureProbe");

            foreach (ManagementBaseObject obj in mySearcher.Get())
            {

                if (obj == null)
                {
                    label1.Text = "didn't find";
                }
                else
                {
                    label1.Text = obj["Accuracy"].ToString ();
                }

}
//---Code End---//

But No RESULT.

Plz me code for How to Get HardWare Information from CPU like Temparature,Voltage,FanSpeed. code in .Net

Thanks

I don't think you can get low level system info such as this unless the manufacturer has supplied a special WMI-compliant device driver with the machine. The WMI classes exist but without the device driver all the properties are null. I did manage to get a value for the current temperature using Acpi: using System; using System.Management; class Test { static void Main() { ManagementObjectSearcher mySearcher = new ManagementObjectSearcher(root\WMISELECT * from MSAcpi_ThermalZoneTemperature); foreach (ManagementObject obj in mySearcher.Get()) { if (obj == null) { Console.WriteLine(didn't find); } else { Console.WriteLine(obj[CurrentTemperature].ToString()); } } } } This gave 2982 on my laptop which is in tenths of a degree Kelvin and so would equate to (2982 - 2732)/10 = 25 degrees celsius. However I suspect this value may be hardcoded. The only documentation I could find for the MSAcpi_ThermalZoneTemperature class is the following: http://www.scriptinternals.com/new/us/support/Internal/WMI_MSAcpi_ThermalZoneTemperature.htm
