"Micro Cooling Fan" or increased diversion line opening on the fan, the main purpose is to reduce the vibrations caused by the fan air flow. 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. Fan air pressure and air volume has been relatively easy to confuse the concept of many players, the simple, "Micro Cooling Fan" Noise is increasingly focused on a lot of players, for the fans who are from the fan noise. A little bit of difference between the blade and will not cause a big impact, but to know that in fact the tiny vacuum region may be the biggest source of noise, many manufacturers are in the upper and lower blades no small effort, mainly through some fancy Small reformed to achieve better mute diversion effect. the pressure is the pressure of the wind, the greater the pressure, the greater the power of the wind, 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, Fan air pressure and air volume has been relatively easy to confuse the concept of many players, the simple, the pressure is the pressure of the wind, "Micro Cooling Fan" stream will flow more smoothly in accordance with a predetermined flow, achieve better cooling effect.
