Noctua - Bild

The NF-A9 is a highly optimised, premium quality quiet 92mm fan. Featuring Noctuas AAO (Advanced Acoustic Optimisation) 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 Noctuas trusted premium quality make it an elite choice for the highest demands.
 
NF-A9
 
Succeeding the award-winning NF-B9

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 optimisations, the NF-A9 provides higher static pressure and an even better airflow/noise ratio than its much acclaimed predecessor.
 
NF-A9
 
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

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.
 
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
 
Inner Surface Microstructures
 
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.
 
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 screws and other mounting systems.
 
SSO2
 
SSO2  SSO2 Bearing

The NF-A9 features the furher 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.
 
PWM
 
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.
 
LNA
 
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.
 
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.
 
Warranty
 
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 of more than 150.000 hours rating and comes with a full 6 years manufacturer’s warranty.
