1, "Micro Cooling Fan" of power
       The greater the power of the light bulb, the greater the power of the speaker louder, that the fan power, the stronger the greater the natural wind, strong wind cooling function better. Although theoretically power the bigger the better, but look at this is not enough, we have to combine fan material and works to integrate the comparison.
       2, "Micro Cooling Fan" of speed
       The fan speed with the same power is the bigger the better, the higher the speed, the wind is bigger, better heat dissipation. But the high speed will cause high vibration and noise will follow, and the higher speed also has a great impact on the life of the fan.
       3, "Micro Cooling Fan" material
       Now popular on the market are made of aluminum or plastic. Aluminum fan exchange fan material is generally lower exchange fan cooling performance, small amount of wind. DC fans are generally plastic material.
