Noctua Fan NF-A14 ULN 140x140x25mm 3Pin SSO2 Bearing A-Series Blade Geometry Retail
  • Overview
  • Specification

The NF-A14 is a premium quality quiet 140mm fan with a square frame that complies with Noctua’s AAO (Advanced Acoustic Optimization) standard. Its square shape and 140mm mounting holes (124.5mm spacing) make it ideal for use on water cooling radiators or as an upgrade for 140mm 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 800/650rpm 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.

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 140mm 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 140mm Frame

The NF-A14’s square 140mm frame with 140mm mounting holes (124.5mm spacing) makes it a premium grade replacement for common 140mm case fans and perfect for use on 140mm 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.
