Abstract
A thermal management device for controlling the temperature of a computer processor chip, by controlling the operating speed of the processor, including a temperature sensitive circuitry incorporated within a packaged clock chip for connection to a processor. A thermal management method for controlling the temperature of a computer processor chip includes sensing a temperature with a temperature dependent circuitry integrally formed in a packaged clock chip, in which the sensed temperature is a function of the temperature of the computer processor chip, generating a clock control signal with the temperature dependent circuitry and sending the clock control signal to a clock generator also integrally formed in the clock chip, and sending a clock signal from the clock generator to the computer processor chip in order to control the operating frequency, and thus the temperature, of the processor.
