Overview


Having received dozens of awards and recommendations from international hardware websites and magazines, the NF-A20 has established itself as a default choice when it comes to premium-quality 200mm fans. The chromax.black.swap edition combines the NF-A20’s signature quiet cooling performance with an attractive all-black design and a bundle of swappable red, white, blue, green, yellow and black anti-vibration pads that allow the colour-customisation of the fan to match individual build colour schemes. For further customisation, a wide range of accessories such as coloured cables and anti-vibration mounts are available separately. Topped off with Noctua’s trusted premium-grade SSO2 bearing, more than 150,000 hours MTTF and 6-year manufacturer’s warranty, the NF-A20 PWM chromax.black.swap is the perfect choice for all users who value individual, focused build aesthetics just as much as class-leading quality and performance.




At-a-glance


  • 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

  • Award-winning NF-A20 design: Having received dozens of recommendations from the international press, Noctua’s NF-A20 has become a proven premium choice for 200mm cooling needs. Its renowned efficiency has convinced tens of thousands of customers all over the world

  • 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

  • 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

  • Metal bearing shell: In order to guarantee the highest possible degree of manufacturing precision, minimum tolerance and excellent long-term stability, the chromax edition fans sport a CNC milled bearing shell made entirely from brass

  • Optional coloured anti-vibration mounts: To complement the coloured anti-vibration pads included with the fans, users can purchase chromax line NA-SAV2 anti-vibration mounts that enable the convenient, quick and vibration-free installation of fans in standard mounting holes for case fans

  • Optional coloured cables: Noctua’s chromax line fans use a modular cabling system and come pre-fitted with a fully sleeved black NA-EC1 30cm cable. For refined colour coordination, white, red, blue, green and yellow 30cm NA-EC1 cables plus corresponding NA-YC1 y-cables are available separately

  • SSO2 bearing: The NF-A20 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

  • 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
