Monitor BIOS Temp

[Guest]

My motherboard has two temperature probes on the motherboard. One to measure
case temp, the other to measure CPU temp. This PC is used as an HTPC, so
adequate cooling is always a concern.

I would like to write a C# app service that monitors the temp and displays
it on screen when the limits are exceeded. First question, is how do I
retrieve these temperature values from the BIOS using C#? Second, how do I
write a transparent warning on top of all other windows that displays a
warning. The PC is mainly used for watching movies and it would be nice if
the on screen display would just pop up during the movie when needed. This
app will also perform a PC shutdown when temps get too high, especially since
the pc is always on.

Look into using WMI to get the temperature of the CPU. Here is an
article that describes it:

I have determined that in order to read the temperature from the BIOS I need
to access the Win32_TemperatureProbe class. In this class, exists a
CurrentReading property which is type sint32. This sint32 type contains
Description of type string which contains the temperature value. My
question, is how do I get the value of this description field under the
CurrentReading? My main problem is that I do not know how to cast to sint32
type since it is not defined.


ManagementClass processClass = new
ManagementClass(@"root\cimv2:Win32_TemperatureProbe");
foreach (ManagementObject service in processClass.GetInstances())
{
Console.WriteLine("Service = " +
service.GetPropertyValue("CurrentReading.Description"));
}

SInt32 is "signed int" or simply an int.

sInt32 is a signed 32 bit integer see the following:

http://msdn.microsoft.com/library/d...ml/frlrfsystemmanagementcimtypeclasstopic.asp

therefore you can convert it to System.Int32 using System.Convert.ToInt32
