WMI CPUTemp Always Returns Same Value - c++

Question

I'm trying to get my CPU's temperature from WMI. But when i execute code from admin command prompt. It always returns same value;
"CPU = 39.050000 C".
I don't know where i've made mistake. My OS is Windows 10 64-bit and I use Visual Studio 2017 15.1 .I wrote same code on C# and it returns same value too just 39. I did some research but I'm still not sure how to approach this.
#define _WIN32_DCOM
#include <iostream>
#include "stdafx.h"
using namespace std;
#include <comdef.h>
#include <Wbemidl.h>
#pragma comment(lib, "wbemuuid.lib")
HRESULT GetCpuTemperature(LPLONG pTemperature)
{
if (pTemperature == NULL)
return E_INVALIDARG;
*pTemperature = -1;
HRESULT ci = CoInitialize(NULL);
HRESULT hr = CoInitializeSecurity(NULL, -1, NULL, NULL, RPC_C_AUTHN_LEVEL_DEFAULT, RPC_C_IMP_LEVEL_IMPERSONATE, NULL, EOAC_NONE, NULL);
if (SUCCEEDED(hr))
{
IWbemLocator *pLocator;
hr = CoCreateInstance(CLSID_WbemAdministrativeLocator, NULL, CLSCTX_INPROC_SERVER, IID_IWbemLocator, (LPVOID*)&pLocator);
if (SUCCEEDED(hr))
{
IWbemServices *pServices;
BSTR ns = SysAllocString(L"root\\WMI");
hr = pLocator->ConnectServer(ns, NULL, NULL, NULL, 0, NULL, NULL, &pServices);
pLocator->Release();
SysFreeString(ns);
if (SUCCEEDED(hr))
{
BSTR query = SysAllocString(L"SELECT * FROM MSAcpi_ThermalZoneTemperature");
BSTR wql = SysAllocString(L"WQL");
IEnumWbemClassObject *pEnum;
hr = pServices->ExecQuery(wql, query, WBEM_FLAG_RETURN_IMMEDIATELY | WBEM_FLAG_FORWARD_ONLY, NULL, &pEnum);
SysFreeString(wql);
SysFreeString(query);
pServices->Release();
if (SUCCEEDED(hr))
{
IWbemClassObject *pObject;
ULONG returned;
hr = pEnum->Next(WBEM_INFINITE, 1, &pObject, &returned);
pEnum->Release();
if (SUCCEEDED(hr))
{
BSTR temp = SysAllocString(L"CurrentTemperature");
VARIANT v;
VariantInit(&v);
hr = pObject->Get(temp, 0, &v, NULL, NULL);
pObject->Release();
SysFreeString(temp);
if (SUCCEEDED(hr))
{
*pTemperature = V_I4(&v);
}
VariantClear(&v);
}
}
}
if (ci == S_OK)
{
CoUninitialize();
}
}
}
return hr;
}
Here is my main code
int main(int argc, char **argv)
{
LONG temp;
GetCpuTemperature(&temp);
printf("CPU = %lf °C\n", ((double)temp / 10 - 273.15));
getc(stdin);
return 0;
}
Edit:Wrong info.

In my opinion,it is none of VARIANT's business, because of this command line in Windows:
"wmic /namespace:\\root\wmi PATH MSAcpi_ThermalZoneTemperature get CurrentTemperature"
This command needs Administrator role, then you will always see the same values.
