"Micro Cooling Fan" wind x = average wind speed over the air space. Visible, fan air volume depends on the size of the size of the basic level of wind speed and wind through the area. Over the same area of the wind, the higher the wind speed, the greater the air flow; the same wind speed, the greater the area of wind, the greater the amount of wind. "Micro Cooling Fan" is to rely on the air blown through the air-cooled heat sink fins, away heat exchange fins on the heat accumulation. Obviously, using the same heat sink and air flow pattern structure, "Micro Cooling Fan", the more air per unit time through, the heat removed also more. Therefore, other things being equal, we can say the actual amount of air cooling effect of wind plays a decisive role.
