Noctua NF-A9 PWM-CH-BK-S
Award-winning NF-A9 designHaving received dozens of recommendations from the international press, Noctua’s NF-A9 has become a proven premium choice for 92mm cooling needs. Its renowned efficiency has convinced tens of thousands of customers all over the world.
chromax.black.swap editionMaximising 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 coloursThe NF-A9 PWM chromax.black.swap comes with 4 white, red, blue, green and yellow as well as 8 black NA-AVP5 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-SAVP5 sets for outfitting both sides in one colour can be purchased separately.
Optional coloured cablesNoctua’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 mountsTo 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.
Flow Acceleration ChannelsThe NF-A9 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 frameNoctua’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 DesignNoctua’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 MicrostructuresWith 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 BearingThe NF-A9 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.
