Abstract
A method and apparatus for measuring the temperature of a computer system provides a first temperature sensor, positioned around or on a CPU, for sensing the temperature of the CPU or around the CPU. A first A/D converter is used to convert the temperature sensed by the first temperature sensor into a first temperature value. At least one second temperature sensor, positioned inside the housing, senses the temperature around the housing. At least one second A/D converter converts the temperature sensed by die second temperature sensor into a second temperature value. The first temperature value and second temperature value are input to a control circuit, and a suitable value to output a control signal for controlling the speed of the fan is chosen so as to precede the heat dissipating of the computer system.
