Used in many applications "Tiny Cooling Fan" to cool down, but the fans will bring mechanical failure, increasing power consumption and noise. Therefore, the fan speed should be monitored and controlled in order to solve these problems, so that the fan is more reliable, lower power consumption and noise. Since the DC brushless "Tiny Cooling Fan" easy to use, reliable, and therefore is the preferred solution of most electronic products. It is a two-terminal devices, can work together with the DC voltage. Dc voltage voltage 5V, 12V, 24V and 48V, 12V fan of the current election and more.
