Batch-file get CPU temperature in °C and set as variable

Question

How do i get a batch-file to work out the temperature of the Cpu and return it as a variable. I know it can be done as i have seen it been done. The solution can use any external tool. I have looked on Google for at least 2 hours but found nothing. Can any one help. Thanks.

Answer 1

You can use wmic.exe:

wmic /namespace:\\root\wmi PATH MSAcpi_ThermalZoneTemperature get CurrentTemperature

The output from wmic looks like this:

CurrentTemperature
2815

The units for MSAcpi_ThermalZoneTemperature are tenths of degrees Kelvin, so if you want celsius, you'd do something like this:

@echo off

for /f "delims== tokens=2" %%a in (
    'wmic /namespace:\\root\wmi PATH MSAcpi_ThermalZoneTemperature get CurrentTemperature /value'
) do (
    set /a degrees_celsius=%%a / 10 - 273
)

echo %degrees_celsius%

A few things:

1) The property may or may not be supported by your hardware.

2) The value may or may not update more than once per boot cycle.

3) You may need Administrative privileges to query the value.

Answer 2

Here is an example which keeps the decimal values and uses the full conversion value.

Code

@echo off
for /f "skip=1 tokens=2 delims==" %%A in ('wmic /namespace:\\root\wmi PATH MSAcpi_ThermalZoneTemperature get CurrentTemperature /value') do set /a "HunDegCel=(%%~A*10)-27315"
echo %HunDegCel:~0,-2%.%HunDegCel:~-2% Degrees Celsius

Output

38.05 Degrees Celsius

Answer 3

If you computer support it you can try like this :

 wmic /namespace:\\root\wmi PATH MSAcpi_ThermalZoneTemperature get CurrentTemperature

This will output the temperature in degree Kelvin.
