    摘要: A circuit board adapted to a fan comprises a circuit region and a heat-dissipative film. The circuit region is provided on a first surface of the circuit board and comprises at least one heat-generating component thereon. The heat-dissipative film is coated on an edge portion of the first surface and is in contact with the heat-generating component. A plurality of openings through the heat-dissipative film, a protrusion of the circuit board, a cutout in the protrusion to expose the heat-generating component to airflow, etc., have been disclosed and claimed for enhancing the efficiency in heat dissipation. A heat sink may also be provided on a second surface opposite to the first surface of the circuit board. The heat sink is connected to the heat-dissipative film to help dissipate the heat generated by the operation of the fan.

    摘要: An alerting method for fan failure first reads a target value of rotating speed of a fan motor. Predetermining values of each parameters of the fan motor is calculated according to the target value of rotating speed of the fan motor. If a current value of rotating speed of the fan motor is lower than the target value of rotating speed of the fan motor, the failure recorded in a counter is added one time. If a current peak value of the fan motor is higher than a first predetermining current value, the failure recorded in the counter is added one time. If the duration of the current which is higher than a second predetermining current value of the fan motor is higher than a predetermining duration, the failure recorded in the counter is added one time. An alarm signal is sent if the failure recorded in the counter is larger than a predetermining time.
