For chassis heat also play a cooling effect of the air volume will cause insufficient heat accumulation circulating inside the chassis. Exhaust "Micro Cooling Fan" surrounding hinder relatively much less, then the air pressure is much larger than the amount of the claim. At the same time, the heat inside the chassis can be more quickly discharged outside of the chassis. In addition, most of the chassis side and a top layer of thermal windows only punch mesh design, it is characterized by the use of wind capacity "Micro Cooling Fan" is a good choice. The inclination angle of the fan blades and blade curvature of the two factors that affect the value of a fan pressure in large city. The inclination angle of the blades and the greater curvature values, at the same rotational speed, the greater the pressure supplied. This "Micro Cooling Fan" is particularly suitable for use in front of the chassis, as the intake fan to use.
