Thermal Management [Thermal Monitor 1]
The Thermal Management configuration option allows you to select the thermal monitor
the CPU will use to monitor its own operating temperature. Once the thermal monitor
detects that the CPU is reaching its maximum operating temperature, the thermal monitor
will automatically throttle the CPU (reduce the number of CPU processing cycles) in order
to cool the CPU down to a safe operating temperature. Once at a safe operating
temperature, the CPU will continue to perform at its peak capacity.

temperature sensing circuit in the CPU that
can act quickly in response to thermal issues.
This circuit monitors the most active areas of
the CPU-die at all times and will quickly lower
the CPU temperature by throttling the internal
CPU clock speed when the CPU approaches
its maximum operating temperature.
Thermal Monitor 2 decreases or increases the
CPU clock and core voltage according to the
CPU load. The CPU temperature is also
automatically decreased, when the core
voltage is decreased.
