The NF-A15 is a premium quality quiet 140 mm fan with a round frame that complies with Noctua's AAO (Advanced Acoustic Optimization) standard. The NF-A15's frame features 120 mm mounting holes (105 mm spacing) and has been enlarged to 150 mm width in order to provide superior performance on today's high-end CPU coolers. Featuring sophisticated aerodynamic design measures such as flow acceleration channels, the NF-A15 further improves the renowned quiet cooling performance of the award-winning NF-P14. Noctua's custom designed PWM IC for fully automatic speed control and reference class SSO2 bearings guarantee superb running smoothness and excellent long-term stability.

Productspecificaties

• Succeeding the award-winning NF-P14
  Noctua's NF-P14 fan has become a default-choice among PC enthusiasts looking for a premium quality quiet 140 mm fan. Thanks to its thoroughgoing aerodynamic optimizations, the NF-A15/14 provides higher static pressure and an even better airflow/noise ratio than its much acclaimed predecessor.
• Round 140 mm frame with 150 mm width
  The NF-A15 is tailor-made for use on today's high-end CPU coolers: While its 150 mm width matches those of most high-end heatsinks, its 140 mm height doesn't make it extend on top and thus ensures best case compatibility. The NF-A15's standard 120 mm mounting holes (105 mm spacing) also make it an ideal performance upgrade for 120 mm case or CPU fans.
• Flow acceleration channels
  The 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 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 plowing 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.
• Integrated anti-vibration pads
  Integrated anti-vibration pads made from extra-soft silicone minimize the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems.
• SSO2 bearing
  The NF-A15 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.
• Metal bearing shell
  In order to guarantee the highest possible degree of manufacturing precision, minimum tolerance and excellent long-term stability, the NF-A15 sports a CNC milled bearing shell made entirely from brass.
• Custom designed PWM IC with SCD
  Supporting fully automatic PWM speed control, the NF-A15 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.
• LNA Low-Noise Adaptor
  The NF-A15 PWM is supplied with a Low-Noise Adaptor that reduces the maximum fan speed from 1200 to 900 rpm. The L.N.A can be used either to run the fan at a fixed speed of 900 rpm or to cap the maximum speed when using automatic PWM control.
• Extensive cabling options
  The fan's short 20 cm primary cable minimizes cable clutter in typical applications while the supplied 30 cm extension provides extended reach when necessary. Both cables are fully sleeved and the supplied 3:4 pin adaptor allows to connect the fan directly to the power supply.
• Ultra-low power consumption
  Despite of its further improved performance, the NF-A15 PWM consumes only 0.96 W of power, which amounts to a reduction of about 20% as compared to its predecessor. This doesn't only make it eco-friendly but also helps to cut down the electricity bill!
