Patent ID: 6873883

Claim:
An electronic system, comprising: an electronics unit; a temperature control logic coupled to said electronics unit; and a fan coupled to said temperature control unit; wherein maid temperature control unit implements a first temperature control protocol upon system initialization and changes to a second temperature control protocol if said electronics unit asserts a temperature signal, the first and second temperature control protocols effecting the speed of the fan; wherein said first temperature control protocol comprises at least two fan speeds, a higher fan speed being selected when the temperature, recorded by a temperature sensor, exceeds a first temperature threshold and a lower fan speed selected when the temperature is below the first temperature threshold; and wherein said second temperature control protocol comprises at least two fan speeds, a higher fan speed being selected when the temperature, recorded by a temperature sensor, exceeds a second temperature threshold and a lower fan speed selected when the temperature is below the second temperature threshold, said second temperature threshold being less than the first temperature threshold.
