Noctua Unveils its Flocked Surface Fans
 

Noctua showed off its newest innovation in PC fan design, the Flocked Surface impeller. Simply put, these fan impellers feature fibrous flock layers along the surface, which creates a turbulent boundary layer of air, much like dimples do on golf balls, resulting in increased air-flow, and decreased air-flow separation (whiplash). Noctua is flocking its fans in two ways, flocked impeller, and flocked frame interior. Examples of both are pictured below.
