CPU Temp Probes

I have searched the web for a script that performs temperature probes but had no luck in getting the real picture until wbemtest helped me find classes not included in M$oft's Scriptomatic.

Follow the instructions below to test if the script will work on your machine for CPU temperature probe:

1. Launch wbemtest


2. Click connect


3. Change the namespace to "root\WMI" then click Connect


4. Click Query, supply the query "Select * from MSAcpi_ThermalZoneTemperature" , then click Apply


5. Double click on the result to view the class properties:


If you are able to view the results then it's ok to proceed with the scriplet.

Below is the script that probes for CPU temperature via MSAcpi_ThermalZoneTemperature. The initial results are in 10ths of degrees in Kelvin so I had to convert the results to Celcius and Farenheit.
