Noctua displayed its new innovation in fan design, called Focused Flow. One of the first fans that use this design come in 120 mm size. Its design goal is to channel (or "focus") air flow towards the center of the fan, making it ideal for use with heatsinks and radiators. The biggest design change here is the stator guide vanes, that are a set of structures permanently fixed between the frame and the center. There are a number of innovations that improve air flow and reduce noise. Notable features are micro-structures on the inner-walls of the frame that dampens the whipping noise made by rotating fan-blades, and integrated vibration dampening material at the edges. The new Focused Flow 120 fan will be used by Noctua on all its upcoming CPU coolers.
