- Context
I had a problem with my water cooling system on the desktop and I needed to check the temperature of the CPU.
I replaced the water cooling and wanted to get the CPU temperature directly in Windows w/o installing a third party software.
- Issue
The task manager in Windows doesn’t display the CPU temperature but you can get the GPU temperature. Nice, but it’s not what I was looking for.
- Solution
To get it in Celsius, you need to divide by 10 and substract 273. The original value is stored as tenths of Kelvin.
(Get-CimInstance -Namespace root/WMI -ClassName MSAcpi_ThermalZoneTemperature |
Select-Object -Expand CurrentTemperature )/10 - 273.15

I’m getting exactly the same result on my machine. (27.85). I test again later, but the result is a bit strange.
Weird :-), I’ve tested on a laptop, I get 49.05.
I’ve tested in a VM, it says ‘Unsupported’ (was expected, right).
On a older laptop, the Get-CimInstance returns more than 1 instance
…
(Get-CimInstance -Namespace root/WMI -ClassName MSAcpi_ThermalZoneTemperature |

Does give me blood on my HP desktop.
I had this in a virtual machine
