Award-winning NF-A15 designHaving received more than 100 awards and recommendations from the international press. Noctua's NF-A15 has become a proven premium choice for 140mm 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-A15 HS-PWM chromax.black.swap comes with 8 black. white. red. blue. green and yellow anti-vibration pads respectively. which allows the fan to be fully colour-customised in order to coordinate it with other components or popular build schemes.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.Round 140mm frame with 150mm widthThe NF-A15 is tailor-made for use on today's high-end CPU coolers: While its 150mm width matches those of most high-end heatsinks. its 140mm height doesn't make it extend on top and thus ensures best case compatibility. The NF-A15's standard 120mm mounting holes (105mm spacing) also make it an ideal performance upgrade for 120mm case or CPU fans.Flow Acceleration ChannelsThe NF-A15 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 suc
