"Small Cooling Fan" technology and performance has been completely reached a very advanced stage, and there are always new technologies emerge. Size fan from 8mm to 280mm, voltage 5V, 12V, 24V, 48V, 110V, 220V, 380V, the shape of a square, circular, Marquise and so on. Cooling fan works by energy conversion to be achieved, namely: energy → electromagnetic energy → mechanical energy → kinetic energy. "Small Cooling Fan" circuit theory is generally divided into a variety of forms, different uses of the circuit, there will be differences in performance fan. Cooling fan speed, the greater the amount of wind noise will be greater due to additional fan vibration itself also can not be ignored. Of course, the fan itself high quality shock will be small, but the first two were is difficult to overcome.
