Noctua - Bild

Featuring Noctua’s AAO frame and sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A9x14 is a highly optimised, premium quality quiet fan in 92x14mm size. Due to its thickness of only 14mm, the NF-A9x14 is a perfect match for low profile CPU coolers and all other applications that require slimmer fans. Noctua’s custom-designed PWM IC for fully automatic speed control and reference class SSO2 bearings guarantee superb running smoothness and excellent long-term stability. Topped off with modular cabling, a Low-Noise Adaptor and 6 years manufacturer’s warranty, the NF-A9x14 is a premium choice for the highest demands.



Focused Flow 14mm Low Profile Design
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.

Focused Flow Flow Acceleration Channels
The NF-A9x14 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise. button

Heptaperf AAO Frame
Noctua’s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua’s proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan’s performance/noise efficiency. button

Stepped Inlet Design Stepped Inlet Design
Noctua’s Stepped Inlet Design adds turbulence to the influx in order to facilitate the transition from laminar flow to turbulent flow, which reduces tonal intake noise, improves flow attachment and increases suction capacity, especially in space restricted environments. button

Inner Surface Microstructures Inner Surface Microstructures
With the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency. button

Integrated Anti-Vibration Integrated Anti-Vibration Pads
Integrated Anti-Vibration Pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard mounting systems and fan clips used on heatsinks.

SSO2 SSO2 Bearing
The NF-A9x14 features the further optimised second generation of Noctua’s renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability. button

PWM Custom designed PWM IC with SCD
Supporting fully automatic PWM speed control, the NF-A9x14 uses Noctua’s novel, custom designed NE-FD1 PWM IC that integrates Smooth Commutation Drive (SCD) technology. By providing smoother torque impulses, SCD suppresses PWM switching noises and thus makes the fan quieter at lower speeds. button

LNA Low-Noise Adaptor
The NF-A9x14 is supplied with a Low-Noise Adaptor (L.N.A.) that reduces the maximum fan speed from 2200 to 1700rpm. The L.N.A can be used either to run the fan at a fixed speed of 1200rpm or to cap the maximum speed when using automatic PWM control.

Cabling Options Extensive Cabling Options
The fan’s short 20cm primary cable minimises cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary. Both cables are fully sleeved and a 4-pin y-cable allows to connect a second NF-A9x14 fan to the same PWM fan header for automatic control.

Warranty 6 years manufacturer’s warranty
Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-A9x14 features an MTBF rating of more than 150.000 hours and comes with a full 6 years manufacturer’s warranty.

28.11.2014 - mod-your-case.de NH-D9L
Test verdict: "Mit dem NH-D9L geht Noctua einen etwas anderen Weg als bei dem kürzlich getesteten NH-U9S und kreiert einen sehr kleinen Twin-Tower-Kühler, welcher in der Theorie mit bis zu drei Lüftern bestückt werden kann. Durch diesen Aufbau ist Noctua ein sehr guter Spagat zwischen einer guten Kühlleistung und einer sehr hohen Kompatibilität gelungen. Die Kühlleistung liegt trotz der im Vergleich zum NH-U9S geringeren Masse und dem mittig montierten Lüfter auf einem sehr guten Niveau." (Patrick Seus, mod-your-case.de)

27.11.2014 - mod-your-case.de NH-U9S
Test verdict: "Mit dem NH-U9S hat Noctua wieder einmal gezeigt, dass man ein gutes Produkt mit viel Entwicklungsarbeit noch besser machen kann. Dies bezieht sich nicht nur auf die Kühlleistung des neuen NH-U9S, sondern auch auf die Kompatibilität." (Patrick Seus, mod-your-case.de)

Test verdict: "After I spent some time having fun with the biggest fans included in the series I can say that I am really impressed to see the classic NF-P14 revived in the shape of two brand new, much cheaper versions with absolutely renewed appearance and much better performance."
