As a "220V Cooling Fan" One centrifugal fan with axial fans both fans have completely different forms of the blast. Also beginning to be used in CPU cooling among computer users is often referred to as "turbo-fan." This fan is advantageous in that a good solution to the "dead zone" problem. Centrifugal "220V Cooling Fan" and conventional fan except that their blades rotate within a vertical plane, the inlet located on the side of the fan. Radiator underside received more uniform flow distribution. The primary benefits of the lateral hair is completely resolved wind blind, because "220V Cooling Fan" is a parallel flow through the cooling fins, the four sides of the cross flow velocity airflow fastest CPU and hot spots located just one edge.
