Beskrivelse af varen

The NF-A9 is a highly optimised, premium quality quiet 92mm fan. Featuring Noctua’s 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 Noctua’s trusted premium quality make it an elite choice for the highest demands.

Succeeding the award-winning NF-B9                                                                

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.                                                       
 
Flow Acceleration Channels                                                                

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                                                                

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

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 Pads                                                                

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 Bearing                                                                

SSO2 Bearing

                                                                        The NF-A9 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.                                                        
 
Smooth Commutation Drive 2                                                                

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-A8 remarkably quiet even at very close distances.                                                        
 
3 speed settings for full flexibility                                                                

3 speed settings for full flexibility

                                                                        Providing 2000, 1650 and 1200 rpm speed settings via the supplied Low-Noise and Ultra-Low-Noise Adapters, the NF-A8 FLX (Flexibility) can be fine-tuned for superior airflow or maximum quietness.                                                       
 
Extensive 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 the connection of a second NF-A9 PWM fan to the same PWM fan header for automatic control.                                                       
 
6-year manufacturer’s warranty                                                                

6-year 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-year manufacturer’s warranty.
