Creation Instructions (5) When the upper end point is shown in the figure, it represents the high-speed gear; when it turns to the middle end point, it represents the medium-speed gear; when it turns to the lower end point, it represents the low-speed gear. In other words, by manually turning the adjustment knob 2 3, the fan can be operated at high speed, medium speed or low speed to generate the corresponding cooling air volume according to the actual load of the computer. The details are left to be described later. Of course, the speed adjustment buttons 2 3 can also increase the gears as needed, but in general, the three gears of high, medium and low speed can basically meet the demand. In addition, the adjusting knobs 2 and 3 also have a closing position. When the knob is turned to this closing position, the fan stops running because there is no positive voltage supply. Please refer to the fourth and fifth figures again. The speed adjustment device 2 further includes a plurality of speed control circuits 2 4, and each speed control circuit 2 4 is connected to a speed adjustment button 2 3 and a fan power connector 2 respectively. Between 2 is mainly composed of a diode for rectification and a resistor for reducing the voltage.
