Due to continuously computer performance were development.More and more functions are integrated into the computer.As a result, the computer processing capacity is increasing day by day. These data include multimedia data and 3D animation data.In order to meet the processing needs a large amount of data, more and more chip set is placed in the host.At the same time, CPU and chip set is frequently improvement.
For notebook computers in appearance is requirements of light, thin and small, so this is another challenge by designers.In a limited space, how to dissipate the heat generated by the system is a difficult problem.How to balance the system efficiency, system comfort( Including the notebook computer case temperature, the noise generated of the fan rotation), and the running time system is an important part of notebook computer design.
CPU is the largest heat source in the system. It is an importance goal in computer temperature detection. At present,CPU contains a diode to provide remote temperature detection to provide a temperature sensor directly detect the CPU inner core temperature.And controlling the internal temperature exactly to avoid high temperature burn out the computer.
