Abstract:
A computer system, comprising:a CPU, wherein said CPU further comprises: a CPU core; clock control logic coupled to said CPU core and providing a periodic clock signal to said CPU core; at least two temperature response elements within said CPU; wherein a first temperature response element is adjacent to said CPU core; a temperature sensor coupled to said first temperature response element, said temperature sensor including a second temperature response element, and said temperature sensor capable of monitoring the temperature of said first and second temperature response elements; and thermal control logic coupled to said temperature sensor and said clock control logic; a fan coupled to said thermal control logic; wherein said temperature sensor provides a value indicative of the temperature of said first and second temperature response elements to said thermal control logic and said thermal control logic independently controls the frequency of the clock signal provided to said CPU core and the speed of said fan based on the temperatures of the first and second temperature response elements.
