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.

"Flocked Surface Fans" AKA super cute fluffy fans for your PC to make it "quieter".



It's actually just to make it look much cuter and adorable. Posted on Jun 2nd 2014, 7:15 Reply

Ever took the frame from a fan and removed as much of the plastic as possible that holds the frame to it ?, well that's a major part that makes a air flow noise. So what i would like to see if thin metal bars holding the motor to the frame although would take some work to get the wiring to the side but it would make even a fan like the Cougar fans even more silent.

Their previous line of fans already have the flocks in the frame. Posted on Jun 2nd 2014, 8:00 Reply

I've never seen flocks on fans before. I must look for a review if these actually work. I hope they put some effort into Slim fans as well. So far Scythe's are my favourites when it comes to 12mm thickness, but competition can help a bit there. Posted on Jun 2nd 2014, 8:39 Reply

That surface would seem to impede airflow compared to a slick one. Unless your goal is to build a pimp rig :pimp: Posted on Jun 2nd 2014, 15:47 Reply

btarunr Noctua is flocking its fans in two ways, flocked impeller, and flocked frame interior. I wonder why they don't just make a fan with both flocked impeller and flocked frame interior. There'd still be plenty of room for Noctua to splash their signature colors not to mention just putting those colors on the flocked parts.

Prima.Vera A month? Are you keeping your PC on the construction yard ?? :)))) On the dry end of summer, my dust filters can be really clogged in a week. I usually have to clean them out at least every two weeks, and never less than every month. On the dry end of summer, my dust filters can be really clogged in a week.
