"Micro Cooling Fan" of air pressure and air volume has been relatively easy to confuse the concept of many players, simply, is the pressure of the wind pressure, the greater the pressure, the greater the force of the wind, the chassis more easily punching , blow through the air filter and other components. The air flow can be understood as the same time the gas flow through the fan size, at the same time, you can exchange more airflow to enhance heat dissipation. For CPU cooler for cooling fin area and density row determines the cooling effect, of course, there are also inseparable from the fan. Behind the fan and cooling fins is a row, so they need a large penetration of wind pressure fan, in order to better heat away.
