The performance of the cooling fan - — Speed and current
speed: the fan blades rotate in a unit time the number of weeks, the unit is commonly RPM, namely the RPM. Speed can affect the wind speed, air volume, air pressure, noise, power, even the strength of the service life of the rotating speed, the higher the fan performance, namely, the faster the wind speed, air volume, high wind pressure, the greater the speed at the same time, the greater the friction, and vibration is big, the noise is big, the service life of bearing loss equipment is short. Dongguan city electronic technology co. , LTD production of a cooling fan air volume, low noise, long service life.
current: fan under the rated working voltage of the fan through the current.
