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.
chromax.black.swap edition Maximising colour choices; Noctua's chromax.black.swap 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 The NF-A20 PWM chromax.black.swap 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 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 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.4mm; 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 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 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 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 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 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 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 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.
