CPU temperature monitoring C#

Question

For a programming project I would like to access the temperature readings from my CPU and GPUs. I will be using C#. From various forums I get the impression that there is specific information and developer resources you need in order to access that information for various boards. I have a MSI NF750-G55 board. MSI's website does not have any of the information I am looking for. I tried their tech support and the rep I spoke with stated they do not have any such information. There must be a way to obtain that info.

Any thoughts?

For at least the CPU side of things, you could use WMI.

The namespace\object is root\WMI, MSAcpi_ThermalZoneTemperature

Sample Code:

ManagementObjectSearcher searcher = 
    new ManagementObjectSearcher("root\\WMI",
                                 "SELECT * FROM MSAcpi_ThermalZoneTemperature");

ManagementObjectCollection.ManagementObjectEnumerator enumerator = 
    searcher.Get().GetEnumerator();

while(enumerator.MoveNext())
{
    ManagementBaseObject tempObject = enumerator.Current;
    Console.WriteLine(tempObject["CurrentTemperature"].ToString());
}

That will give you the temperature in a raw format. You have to convert from there:

kelvin = raw / 10;

celsius = (raw / 10) - 273.15;

farenheight = ((raw / 10) - 273.15) * 9 / 5 + 32;
