Processor Power Management
Thermal Management throttles the processor back as it reaches its maximum
operating temperature. Throttling reduces the number of processing cycles, thereby
diminishing the heat dissipation of the CPU. This cools the unit. Once the CPU has
reached a safe operating temperature, thermal throttling is automatically disabled,
and normal full speed processing begins again.
