Micro Cooling Fan blade and a fixed port

"Micro Cooling Fan" speed of 1200 rpm and down about 10%, the amount of wind 9 blades in uniform is provided under considerable; the use of sleeve bearings, at 1200 rpm to maintain this speed on low noise operation, to mute the effect. "Micro Cooling Fan"fan from the inside to the outside gradually collapsed designed to provide a certain amount of pressure in the bottom of the fan can be measured up to the nearest 43.2CFM, and increase the amount of wind decreased with distance faster, therefore, this "Micro Cooling Fan" for the front and rear of the chassis to install, build chassis cooling channel to use.
