Noctua chromax NF-A9x14 HS-PWM.black.swap - Case fan - 92 mm - black | NF-A9X14 HS-PWM CH.BK.S

Product Features

• Award-winning NF-A9 design
  Having 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 edition
  Maximizing color choices, Noctua's chromax.black.swap edition fans can be color-customized 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 color-coordinated with popular build themes such as all black, black & white or black & red.
• Swappable anti-vibration pads in 6 colors
  The 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 colors with black or going all black, the fan can be coordinated with most popular build color schemes out of the box. Additional NA-SAVP5 sets for outfitting both sides in one color can be purchased separately.
• Optional colored 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 color coordination, white, red, blue, green and yellow 30cm NA-EC1 cables plus corresponding NA-YC1 y-cables are available separately.
• Optional colored anti-vibration mounts
  To complement the colored 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 Channels
  The 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 frame
  Noctua's AAO (Advanced Acoustic Optimization) 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-A9 features the further optimized 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 stabilization, precision and durability.
• Custom-designed PWM IC with SCD
  Supporting fully automatic PWM speed control, the NF-A9 PWM uses Noctua's novel, 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.
• Stops at 0% PWM
  When the fan is set to 0% PWM duty cycle by the motherboard or PWM fan controller, it will stop. This makes it ideal for creating setups with semi-passive cooling that automatically turn the fans off and thus run completely silent at idle if thermals allow.
