What is more, not content with reverse bending "220V Cooling Fan" outlet guide vanes increase the pressure, using a more extreme multi-channel blade design, which mainly two-blade fan based. Two blades opposite inclination, the opposite bending direction, opposite "220V Cooling Fan" direction of rotation, are driven by two motors, the maximum amount of wind in the same circumstances, to provide maximum static pressure is almost doubled. Typical for Delta- Delta GFB series dual-channel blade axial "220V Cooling Fan" Cooler Master recently launched "DualStorm" also belongs to this category.
