Featuring a premium SSO2 bearing, this fan guarantees superb running smoothness and durability, making it an elite choice for demanding PC builds. Broad compatibility with various mounting hole spacings ensures seamless integration into your system. The NF-A20 is a highly optimised, premium quality quiet 200mm fan. Featuring an AAO (Advanced Acoustic Optimisation) standard frame as well as sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A20 brings the renowned quiet cooling performance of Noctua's award-winning A-series to the increasingly popular 20cm form factor. The FLX version provides 800/550rpm speed settings via the supplied Low-Noise Adaptor 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 the NF-A20 an elite choice for the highest demands.Specifications:- Size: 200x200x30 mm- Mounting hole spacing: 154x154, 110x180, 170x170 mm- Connector & pin-configuration: 3-pin- Cable length: 20cm + 30cm NA-EC1 extension cable- Bearing: SSO2- Blade geometry: A-Series with Flow Acceleration Channels- Frame technology: AAO (Advanced Acoustic Optimisation)- Rotational speed (+/- 10%): 800 RPM- Rotational speed with L.N.A. (+/- 10%): 550 RPM- Airflow: 146,9 m³/h- Airflow with L.N.A.: 100,8 m³/h- Acoustical noise: 18,1 dB(A)- Acoustical noise with L.N.A.: 10,7 dB(A)- Static pressure: 1,08 mm H₂O- Static pressure with L.N.A.: 0,51 mm H₂O- Input power (typical): 0,82 W- Input power (max.): 0,96 W- Input current (typical): 0,07 A- Max. input current: 0,08 A- Operating voltage: 12 V- MTTF: > 150.000 hScope of delivery:- Low-Noise Adaptor (L.N.A.)- 3:4-pin adaptor cable- 30cm extension cable- NA-AV3 anti-vibration mounts- NA-AV4 anti-vibration mounts- Fan screwsTechnology:154mm, 110x180mm and 170mm hole spacing:- In order to ensure broad compatibility with today's PC cases, the NF-A20 features three sets of mounting holes: While the 154x154mm and 110x180mm spacing allow it to replace most 200mm fans, the 170x170mm spacing is used by many 230 and 250mm fans, which can thus also be replaced by the NF-A20.*Flow Acceleration Channels:- The NF-A20 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:- Noctu´s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctu´s proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan´s performance/noise efficiency.Stepped Inlet Design:- Noctu´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:- 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 made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems.Smooth Commutation Drive 2:- The latest version of Noctu´s advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations and switching noises. This makes the fan remarkably quiet even at very close distances.Low-Noise Adaptor for full flexibility:- The NF-A20 FLX (Flexibility) is supplied with a Low-Noise Adaptor (L.N.A.) that reduces the maximum fan speed from 800 to 550rpm so that it can be fine-tuned for superior airflow or maximum quietness.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 the supplied 3:4 pin adaptor allows the connection of the fan directly to the power supply.SSO2 bearing:- The NF-A20 features the further optimised second generation of Noctu´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. tradeinn Techinn
