With the reduction in 12V "Tiny Cooling Fan" power, 5V fan of the amount will increase. The field of telecommunications in general use 48V fan. Brushless DC fan commutation rectifier is electronically controlled internal fan, old-fashioned "Tiny Cooling Fan" mechanical engineering brush, which will produce a higher EMI, and easily damaged. The brushless fan with electronic sensors and switches instead of mechanical brushes, thus extending the service life is a simple to use, reliable operation of the terminal devices. DC "Tiny Cooling Fan" different terminal voltage, current, its speed and consumption are also different (proportional).
