Abstract: A method for positioning a display of an icon or text on a fan comprises the following steps: setting any magnetic pole in a stator to be a first magnetic pole and generating a section of a first alternation with a length longer than other alternations when a rotor is magnetized inside of the stator; setting the first alternation to be a starting position and starting displaying procedures of the icon or the text; taking the starting position as 0° and setting a delay time according to an angle of a fan leave at which the icon or the text is displayed; displaying the preset icon or text through luminous bodies. Whereby, the starting position is set depending on the generation of the first alternation, and the displaying procedure of the icon or the text is triggered to allow the fan leaves body to be rotated to a specific angle to display the preset icon or text.

Abstract: A light control structure for a cooling device comprises a hollow frame disposed with a fixing seat connected and fixed at the center of the frame through a plurality of groove strips, at least one lamp inlayed in at least one corner of the frame, a fan pivotally connected onto said fixing seat of the frame and a control circuit installed on the surface of the fixing seat for driving the fan to rotate. Whereby, wires connected with the lamps inlayed in the groove strips are allowed to connect respectively with a control circuit board disposed on the fixing seat by burying and fixing them in the groove strips. The exposition of the flexible wires of the cooling device on the surface of the frame can be prevented so as to allow the wires to be able to be commonly used in all kinds of sizes of frames.

Abstract: A fan and heat sink arrangement includes a heat sink having a circular top center opening surrounded by radiation fins thereof, and a fan, which includes a main fan body suspended above the heat sink and an auxiliary fan body axially connected to the main fan body and received in the circular top center opening of the heat sink.
