"Tiny Cooling Fan" sent per minute, or the total volume of air inhaled in the same heat sink material, the air flow is a measure of the most important indicators of air-cooled heat sink cooling capacity. The larger the fan. The larger the amount of wind, the greater air volume per unit of time can take away more heat. If the "Tiny Cooling Fan" Wind power play than as a weapon. So pressure is the weapon of sharpness. Under other conditions remain unchanged. The actual amount of wind to fan effect plays a decisive role. Aluminum fins "Tiny Cooling Fan" high wind pressure requirements. Copper fins require large amount of wind. The more dense fin For higher pressure requirements. Otherwise, the air flow between the fins will not smooth.
