ThermalZoneTemperature, Win32_Fan, WMI

[Kostia]

Забитая тема, но все равно я так и не смог найти ответа на вопрос получения показателей с датчиков темпиратуры средствами Windows...
Код ниже взят с msdn с небольшими корректировками, но он явно дает не то что нужно, а именно возвращается константа:
