Abstract: The present invention relates to a method of controlling a heat-dissipating fan of a computer device, which is provided with a heat-dissipating fan, a controller, a first sensor unit, and a second sensor unit. The method of the present invention includes the following steps. First, the controller accepts a first signal and a second signal and controls the rotating speed of the heat-dissipating fan according to the first signal. Subsequently, the controller determines the first signal and the second signal. Next, the controller reduces the rotating speed of the heat-dissipating fan corresponding to the first signal to temporarily maintain the rotating speed at a constant to thereby reduce a noise value produced by the heat-dissipating fan.

Abstract: A fan module is disposed in an electrical device. The electrical device has a main board and a casing. The fan module includes a vane module, a fan motor, a circuit board and a fan housing. The vane module has a hub and a plurality of vanes disposed around the edge of the hub. The fan motor is disposed in the hub. The circuit board is used to control the fan motor, so that the vanes rotate related to an axis of the hub for generating an air flow. The fan housing has a main body portion, a protruding portion and a fixing portion, wherein the protruding portion is located in a side of the main body portion, the vane module and the fan motor are disposed in the main body portion and the circuit board is disposed in the protruding portion.

Abstract: An electronic device includes a housing, a module, a main board, and a fan. The module, the main board and the fan are all installed in the housing. The main board divides the interior of the housing into a first space and a second space, and there exists a channel opening between the main board and the module so as to communicate the first space with the second space. The fan is electrically connected to the main board, has a fan outlet and is capable of outputting airflow through the fan outlet to the outside of the housing.
