Different temperature reports

[Philipp Vlassakakis]

hw.acpi.thermal.tz0.temperature is usually the sensor of the CPU.

See ACPI_THERMAL(4)
"For example, each CPU and the enclosure could all be separate thermal zones, each with its ownsetpoints and cooling devices."

Smartctl uses the sensor inside the hard disk.

Philipp
