Micro Cooling Fan smoothness blade design

Leaves smoothness "Micro Cooling Fan": Non-design factors that affect the index, essentially depends on the producers of mold forming process and post-processing. In addition to the design curve is not flat blades will produce turbulence in the rotation, increasing friction, reduce fan efficiency, breakage "dota2雷竞技预测 " performance, increased operating noise. Therefore, to deal with the blade surface smoothness strict control, if the purchased product handling is poor, can only be considered hand-grinding and other means to make up for the follow-up. Although the "Micro Cooling Fan" of the blade section curve more from the same base, various adjustments can be performed also are limited within a certain range, but still with a fan manufacturers made great improvements proposed design very unique.
