The NF-A14 is a premium quality quiet 140 mm fan with a square frame that complies with Noctua's AAO (Advanced Acoustic Optimization) standard. Its square shape and 140 mm mounting holes make it ideal for use on water-cooling radiators or as an upgrade for 140 mm case fans. Featuring sophisticated aerodynamic design measures such as flow acceleration channels, the NF-A14 further improves the renowned quiet cooling performance of the award-winning NF-P14. The ULN version provides super-slow 800/650 rpm speed settings for ultra-low-noise applications and highly noise sensitive users who demand near-silent operation. Its superb running smoothness, reference-class SSO2 bearing and Noctua's trusted premium quality make it an elite choice for the highest demands.

Funkce produktu

• 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-A14 provides higher static pressure and an even better airflow/noise ratio than its much acclaimed predecessor.
• Square 140 mm frame
  The NF-A14's square 140 mm frame with 140 mm mounting holes makes it a premium grade replacement for common 140 mm case fans and perfect for use on 140 mm water cooling radiators, where its square shape will ensure full coverage and best pressure performance.
• Flow acceleration channels
  The NF-A14 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 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-A14 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-A14 sports a CNC milled bearing shell made entirely from brass.
• Smooth commutation drive
  The version of Noctua's advanced smooth commutation drive system ensures superb running smoothness by eliminating torque variations and switching noises. This makes the NF-A14 remarkably quiet even at very close distance.
• LNA 2 speed settings for maximum quietness
  Providing 800 and 650 rpm speed settings via the supplied adaptor, the ULN (Ultra-Low-Noise) version is tailor made for serious silent enthusiasts who demand super-slow running speeds and utmost quietness of operation.
• Ultra-low power consumption
  Despite of its further improved performance, the NF-A14 ULN consumes only 0.48 W of power. This doesn't only make it eco-friendly but also helps to cut down the electricity bill!
