Clover Tiny Cooling Fan

"Tiny Cooling Fan" only three blades is not surprising, the most common is the case fans, but in the small DC brush less fan of this design are rare. As mentioned above, an excessive number of blades, too close, it will increase the air flow disturbance and leaf surface friction, reduce "Tiny Cooling Fan" efficiency, increased operating noise. Tt will not need too much pressure for a number of fins with this 8cm of "TripleBlade" Clover fan. Reducing the number of blades, in order to increase the leaf area, the inclination is also decreased, so the pressure has decreased to certain extent. Although the lack of air pressure, but the larger the distance between the blades, "Tiny Cooling Fan" efficiency, to ensure maximum air flow can still while reducing operating noise.
