    Noctua NF-A4x20-FLX
    Omschrijving
    Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and Noctuas AAO frame, the NF-A4x20 is a highly optimised, premium-quality quiet fan in size 40x20mm. The FLX version provides 5000/4400/3700rpm speed settings via the supplied Low-Noise Adaptors and includes the OmniJoin Adaptor Set for easy connection to proprietary fan headers. Its superb running smoothness, reference-class SSO2 bearing and Noctuas trusted premium quality make it an elite choice for the highest demands.

    40x20mm size
    Compared to Noctuas award-winning NF-A4x10, the NF-A4x20 is twice as thick, which allows for increased static pressure performance and makes the NF-A4x20 ideal for demanding applications with high flow resistance.

    Flow Acceleration Channels
    The NF-A4x20 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
    Noctuas AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctuas proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fans performance/noise efficiency.

    Stepped Inlet Design
    Noctuas 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 mounting systems and fan clips used on heatsinks.

    Smooth Commutation Drive 2
    The latest version of Noctuas 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.

    SSO2 bearing
    The NF-A4x20 features the further optimised second generation of Noctuas renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability.

    3 speed settings for full flexibility
    Providing 5000, 4400 and 3700 rpm speed settings via the supplied Low-Noise and Ultra-Low-Noise Adapters, the NF-A4x20 FLX (Flexibility) can be fine-tuned for superior airflow or maximum quietness.


    OmniJoin adaptor set
    Many devices featuring 40mm fans use proprietary fan headers, so the NF-A4x20 comes with Noctuas OmniJoin adaptor set. Just cut the original fans cable, fix it to the adaptor using the supplied 3M Scotchlok connectors and you can plug the NF-A4x20 to proprietary fan headers!

    Extensive cabling options
    The fans 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.

    6-year manufacturers warranty
    Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-A4x20 features an MTTF of more than 150.000 hours rating and comes with a full 6-year manufacturers warranty.
