CPU Temperature of Dell PC

Hey guys,

I'm trying to get the temperature of my PC via a WMI Query but just can't find it. 

My system is a 

Dell Optiplex 990
Windows 7 Version 6.1.7601 Service Pack 1 Build 7601 x64
Bios Version = Dell Inc. A11. 12/30/2011
SMBIOS = 2.6

with Dell OMCI Version = 8.2.0.154 x64 installed on it.

I've tried via Win32_TemperatureProbe, MSAcpi_ThermalZoneTemperature, and DCIM_NumericSensor none of which have given me any temperature values.

The output of Win32_TemperatureProbe is this

With all the values that are shown in it it says that it's healthy and should be working effectively but it has given me nothing. Any help would be appreciated.

Thanks,
