Micro Cooling Fan technical indicators

"Micro Cooling Fan" wind
Air volume refers to the cooling fan included in the total volume of exhaust or air per minute, if calculated by cubic feet of air volume units is CFM; If you press cubic meter to count, is the CMM. Airflow cooling fan unit is often used CFM (approximately 0.028 cubic meters / minute).
Air flow is the most important indicator to measure the cooling capacity of the cooling fan. Obviously, the greater the amount of air cooling fan its cooling capacity is also higher. This is because the heat capacity of air ratio is certain, larger air volume, which is more air per unit of time can take more heat. Of course, in the case of the same amount of air flow of the cooling effect of the way of wind.
"Micro Cooling Fan" Pressure
Air pressure and air volume is the concept of two opposing. Generally, in the manufacturers cost considerations, to design air volume fan, it is necessary to sacrifice some pressure. If the fan can bring a lot of air flow, but the pressure is small, less wind blew the bottom of the radiator (which is why some high fan speed, air flow is large, but the cooling effect is good reason), on the contrary, it often means big pressure on the small amount of wind, there is not enough cold air and heat sink for heat exchange, can also cause "Micro Cooling Fan" cooling effect is good.
