    摘要: A fan control system. The fan motor is operated normally at not greater than a preset maximum rotation speed. The fan control system has a programmable microcontroller to receive an input voltage and a rotation speed signal corresponding to the actual rotation speed of the fan motor, determining an output signal according to the input voltage and the rotation speed signal, and outputting the output signal; and a fan-driving unit to receive the output signal and adjusting the rotation speed for driving the fan motor according to the output signal. When the rotation speed is lower than a predetermined rotation speed, the rotation speed is in a relation of a first function to the input voltage; when the rotation speed is greater than the predetermined rotation speed, the rotation speed is in a relation of a second function to the input voltage. The first function and the second function are separate mathematical functions, and a first maximum voltage obtained from the maximum rotation speed in the relation of the first function is lower than a second maximum voltage obtained from the maximum rotation speed in the relation of the second function.

    摘要: A heat-dissipating device is provided for generating primary airflow to dissipate heat generated by external heat sources as well as secondary airflow to dissipate heat generated from the interior of the heat-dissipating device. The heat-dissipating device includes a primary fan and a secondary fan coupled with a shaft of the primary fan. The secondary fan is rotated along the shaft to generate the secondary airflow and dissipate heat generated by the heat-dissipating device per se. Thus, the operation temperature of the heat-dissipating device can be lowered to increase its life span.
