For chassis heat also play a cooling effect, "Mini Air Cooling Fan" is not enough air flow will cause heat accumulation circulating inside the chassis. Exhaust fan surrounding hinder relatively much less, on the amount of wind is much larger than wind pressure requirements. At the same time, "Mini Air Cooling Fan" 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, so the use of wind capacity is characterized by "Mini Air Cooling Fan" is a good choice.
