Noctua NF-A9 FLX 92mm Fan

* In stock.

The NF-A9 is a highly optimized, premium quality quiet 92mm fan. Featuring Noctua’s AAO (Advanced Acoustic Optimization) frame as well as sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A9 further improves the renowned quiet cooling performance of the award-winning NF-B9. The FLX version provides 1600/1250/1050rpm speed settings via the supplied Low-Noise Adaptors in order to provide full flexibility in fine-tuning the fan for maximum ventilation performance or near-silent operation. Its superb running smoothness, reference-class SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for the highest demands.

Noctua NF-A9 FLX Features

Succeeding the award-winning NF-R9
Noctua’s NF-B9 fan has become a default-choice among PC enthusiasts looking for a premium quality quiet 92mm fan. Thanks to its thoroughgoing aerodynamic optimizations, the NF-A9 provides higher static pressure and an even better airflow/noise ratio than its much acclaimed predecessor.

Image shows Flow Acceleration Channels logo.

Flow Acceleration Channels
The NF-A9 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.

Image shows AAO Frame logo.

AAO Frame
Noctua’s AAO (Advanced Acoustic Optimization) 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.

Image shows Stepped Inlet Design logo.

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.

Image shows Inner Surface Microstructures logo.

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.

Image shows Integrated Anti-Vibration Pads logo.

Noctua Integrated Anti-Vibration Pads
Integrated Anti-Vibration Pads made from extra-soft silicone minimize the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems.

Image shows SSO2 Bearing logo.

SSO2 Bearing
The NF-A9 features the further optimized 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 stabilization, precision and durability.

Image shows Smooth Commutation Drive 2 logo.

Smooth Commutation Drive 2
The latest version of Noctua’s advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations and switching noises. This makes the NF-A9 remarkably quiet even at very close distance.

3 speed settings for full flexibility logo.

3 speed settings for full flexibility
Providing 1600, 1250 and 1050 rpm speed settings via the supplied Low-Noise and Ultra-Low-Noise Adapters, the NF-A9 FLX (Flexibility) can be fine-tuned for superior airflow or maximum quietness.

Image shows Extensive Cabling Options logo.

Extensive Cabling Options
The fan’s short 20cm primary cable minimizes 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-A8 fan to the same PWM fan header for automatic control.

Image shows 6 years manufacturer’s warranty logo.

6 years Manufacturer’s Warranty
Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-A9 features an MTBF rating of more than 150.000 hours and comes with a full 6 years manufacturer’s warranty.
