Quote:Tcase is not the ambient case temperature.
Ambient case temperature is something entirely different. There is not sensor in the motherboard or CPU to monitor ambient case temperature.
Tcase is the temperature of CPU where it mates with the cooler. Tcase is probably 5-10c lower than actual core temp but that's only a educated guess.
Tcase: Technically this refers to the temperature that you can measure using a thermocouple embedded in the centre of the heat spreader, but this is only done in the factory by Intel or by users willing to drill their heat spreaders open to insert a thermocouple. Therefore Intel provided a diode between and below the cores with a reading calibrated by the BIOS which can be used instead. This reading can vary greatly when the BIOS version is changed, but will not necessarily change if the BIOS calibrations were not altered between versions.
