Big fan of "Micro Cooling Fan" on the large amount of exhaust this argument is wrong, because the fan exhaust volume is a comprehensive index, which is the most direct factor measures the performance of a fan, it's not just about size fan leaf size, but also on the form and design of the blade, the thickness of the fan blades and the angle are related. If a fan blade size is large, but "Micro Cooling Fan" fan if it is flat, then it will not form any airflow, the fan exhaust volume is zero, so the relationship between the amount of exhaust cooling fan, the blade angle is the decisive factor. When buying a fan, if we want to check the amount of exhaust fans, so long as the hands near the fins feel the wind blowing intensity can, usually exhaust volume of "Micro Cooling Fan", even though we are from fan very far place, you can feel the wind to flow.
