Opening or increasing diversion line on "Micro Cooling Fan" fan, the main purpose is to reduce the vibration caused by the blades due to the airflow. Of course, to reduce vibration, noise will be decreased, the air will flow more smoothly in accordance with a predetermined flow, achieve better cooling effect. "Micro Cooling Fan" of wind pressure and wind volume has been relatively easy to confuse the concept of many players, the simple, the pressure is the pressure of the wind, the greater the pressure, the greater the power of the wind, the more likely the chassis punching, air filter and other parts blown through. The wind can be understood as the same time by "Micro Cooling Fan" air traffic volume at the same time, we can exchange more airflow to enhance heat dissipation.
