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

Noctua today introduced the first three models of its new A-series of premium quality quiet fans: The NF-A4x10, NF-A6x25 and NF-A9x14 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.


Noctua’s 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. The new fans will be available immediately at recommended retail prices of EUR 12.90 / USD 15.90 (NF-A4x10), EUR 14.90 / USD 17.90 (NF-A6x25) and EUR 16.90 / USD 19.90 (NF-A9x14). The Noctua NF-A6x25 is shown below.

“We have been getting a lot of requests for 40 and 60mm models both from our industry clients and customers who seek to replace noisy fans in network and storage solutions”, says Mag. Roland Mossig, Noctua CEO. “We’re confident that the new NF-A4x10 and NF-A6x25 are highly competitive offerings for these types of applications, their efficiency really pushes the boundaries in these form factors.”
