Noctua introduces 40, 60 and 92mm A-series fans

Acording to Noctua the new models all feature Noctua’s novel AAO frames and the series’ signature Flow Acceleration Channels for reduced boundary layer separation and improved aerodynamic efficiency. Reference class SSO2 bearing and 6 years manufacturer’s warranty make the new models a stand-out choice for all noise-sensitive 40, 60 and 92mm applications.

The new A series fans use a novel aerodynamic design measure called Flow Acceleration Channels that allows them to significantly improve the airflow to noise performance of conventional, uniform blade shapes. By speeding up the airflow at the crucial outer blade regions, Flow Acceleration Channels reduce suction side flow separation and thus lead to better efficiency and lower vortex noise.

Another aspect that contributes to the NF-A4x10’s and NF-A6x25’s outstanding performance is their reduced motor hub size: Thanks to a streamlined, compact motor design, their motor hub is smaller than with conventional 4 or 6cm fans, which allows for more blade surface area and thus contributes to the fans’ superior efficiency.

Measuring only 14mm in thickness, the NF-A9x14 is much slimmer than standard 92x25mm fans. This makes it ideal for all applications where standard fans would take up too much space, such as low profile CPU coolers in HTPC builds or server environments.

All three fans employ the further optimised second generation of Noctua’s renowned, time-tested SSO bearing as well as Noctua’s AAO (Advanced Acoustic Optimisation) frames that feature integrated anti-vibration pads as well as Noctua’s proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fans’ performance/noise efficiency. Like all Noctua fans, the NF-A9x14, NF-A6x25 and NF-A4x10 have an MTBF rating of more than 150.000 hours and come with a full 6 years manufacturer’s warranty.
