Abstract:
1. A portable computer, comprising: a heat dissipating module having a fan module, wherein the fan module has a corresponding system acoustic level; a microphone, collecting surrounding noises, acoustically isolated from the fan module; a spectrum analysis module, connected to the microphone, analyzing the surrounding noises collected from the microphone to obtain a surrounding acoustic level; and a controlling module having a predetermined temperature of the element, connected to the heat dissipating module and the spectrum analysis module, respectively, wherein the predetermined temperature of the element is set as the maximum temperature, and the surrounding acoustic level is set as the maximum system acoustic level so that an executive operating status is selected from a plurality of operating statuses according to the maximum temperature and maximum system acoustic level, thereby obtaining a corresponding system efficiency and a fan driving voltage.
