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.

03.03.2015 - FunkyKit.com NH-D9L
Test verdict: "The Noctua NH-D9L packs alot of cooling in a little package. If you are needing to save the space but do not want to sacrifice performance the dual fan setup competes pretty close to the big behemoth coolers." (Chris McCart, FunkyKit.com)

03.03.2015 - PureOverclock.com NF-A4x10 5V
Test verdict: "Overall, I believe Noctua makes an excellent product. There really isn’t anything I can complain about except for the price, and even then the price is understandable. If you need good air flow, low noise and have a small form factor case that needs some better fans, I could definitely recommend what Noctua has to offer here." (Josh Jackson, PureOverclock.com)

03.03.2015 - FrostyTech.com NH-U9S
Test verdict: "Given these height and footprint size restrictions, the Noctua NH-U9S is a pretty quiet heatsink that offers very good thermal performance in the sub-125mm tall heatsink category, making it an excellent choice for PCs which are severely space limited. The results are enhanced by adding a second fan, as we've shown over the course of this review. Couple that with awesome build quality and a 6 year warranty and it's not hard to recommend this cooler." (Max Page, FrostyTech.com)

02.03.2015 - Hardwareluxx Community NF-P14s redux-1200 PWM
Test verdict: "Das Ergebnis dieses Reviews zeigt, wie effizient die Redux tatsächlich arbeiten. Auch wenn es sich hierbei nur um 0,15 bis 4,05°C handelt. Die Lautstärke ist bei voller Drehzahl im Vergleich zum TY-147A wesentlich geringer [...]. Für einen angemessenen Preis von ca. 13 Euro bietet Noctua einen erstklassigen und sehr qualitativen Lüfter." (Aliriza Tasdemir, Hardwareluxx Community)
