I am getting CPU temperature using wmi library in Windows 32-bit with Python but I think it's false when compared with the results of Core Temp
Question:
I keep getting the value 30.85° with the following code using the wmi library. Here is my code:
import wmi
w = wmi.WMI(namespace=r'rootwmi')
temp = w.MSAcpi_ThermalZoneTemperature()[0].CurrentTemperature
kelvin = temp / 10
celsius = kelvin - 273.15
fahrenheit = (9/5) * celsius + 32
print(f'Kalvin:{kelvin:^10.2f}tCelsius:{celsius:^10.2f}tFahrenheit:{fahrenheit:^10.2f}')
Here is the result:
Kalvin: 304.00 Celsius: 30.85 Fahrenheit: 87.53
I also want to point out that this value won’t change unless I reboot my laptop, or after waiting around 30 minutes.
Finally, here are the results that are shown in Core Temp 1.15.1 which are changing constantly.
Can you help me interprete this please?
Answers:
While reading wim documentation and on the following thread, I am not getting the current temperature of the CPU but rather somewhere else from the motherboard.
As stated here.
The Win32_TemperatureProbe WMI class represents the properties of a temperature sensor (electronic thermometer).
Most of the information that the Win32_TemperatureProbe WMI class provides comes from SMBIOS. Real-time readings for the CurrentReading property cannot be extracted from SMBIOS tables. For this reason, current implementations of WMI do not populate the CurrentReading property.
