      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 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 is the perfect choice for all users who value individual, focused build aesthetics just as much as class-leading quality and performance.

      Award-winning NH-A20 design 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. design edition
      Maximising colour choices, Noctua’s edition fans can be colour-customised using the included swappable anti-vibration pads as well as optional anti-vibration mounts and cables. This makes them ideal for enthusiasts looking for true premium-grade fans that can be colour-coordinated with popular build themes such as all black, black & white or black & red.
      Swappable anti-vibration pads in 6 colours
      Swappable anti-vibration pads in 6 colours
      The NF-A20 PWM comes with 4 white, red, blue, green and yellow as well as 8 black NA-AVP6 anti-vibration pads. By combining the various colours with black or going all black, the fan can be coordinated with most popular build colour schemes out of the box. Additional NA-SAVP6 sets for outfitting both sides in one colour can be purchased separately.
      Optional coloured cables
      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.
      Optional coloured anti-vibration mounts
      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.
      154mm, 110x180mm and 170mm hole spacing
      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
      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
      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.
      SSO2 bearing
      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.
      Metal bearing shell
      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.
      Custom-designed PWM IC with SCD
      Custom-designed PWM IC with SCD
      Supporting fully automatic PWM speed control, the fan uses Noctua's custom-designed NE-FD1 PWM IC that integrates Smooth Commutation Drive (SCD) technology. By providing smoother torque impulses, SCD suppresses PWM switching noises and thus makes the fan quieter at low speeds.
      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-A20 features an MTTF of more than 150.000 hours rating and comes with a full 6-year manufacturer’s warranty.

      *As there is no fixed industry standard for the size or hole spacing of 200mm, 220mm, 230mm or 250mm fans, please see our case compatibility list and carefully check both the hole setup of your chassis and the available space (the NF-A20 is 30mm thick whereas some other 200mm fans are only 20mm!) in order to verify that the NF-A20 is compatible with your chassis. In case of doubt, please contact your chassis manufacturer.
      Notes and warnings Please refer to our case compatibility list for detailed compatibility information.
