Noctua NF-A14 ULN Fan - 140mm

Noctua is one of the well-known names in the silent cooling sector, with the Austrian manufacturer’s CPU coolers enjoying an excellent reputation. They combine outstanding build quality with high cooling performance and minimal noise generation. The self-developed Noctua fans, which are also available separately to serve as case or CPU fans, play a major role in this.

The NF-A14 is a quiet 140mm premium fan with a square AAO (Advanced Acoustic Optimisation) frame. Its square shape and 140mm mounting holes make it an excellent choice for use on water-cooling radiators or as a case fan. Thanks to advanced aerodynamic design features such as Flow Acceleration Channels, the NF-A14 achieves an even better silent cooling performance compared to the multiple award-winning NF-P14.

The ULN version offers ultra-low speed options (800/650 RPM) for an almost noiseless operation, making it perfect for ultra-low noise applications and especially noise-sensitive users. Its superb smooth running, the SSO2 reference-class bearing, and Noctua’s proven premium quality make the NF-A14 ULN a top solution for the highest demands.

Noctua’s NF-P14 has become a standard solution for PC enthusiasts who require 140mm fans of premium quality. Through extensive aerodynamic optimisations, the NF-A14 achieves even higher static pressure and an improved ratio of airflow to noise compared to its renowned predecessor.

With its square frame and 140mm mounting holes (124.5mm hole spacing), the NF-A14 is an ideal premium upgrade for standard 140mm case fans. At the same time, it is perfect for use on 140mm water-cooling radiators, where the square shape ensures full coverage of the cooling fins and thus the best pressure performance.

The impeller of the NF-A14 is equipped on the intake side with so-called Flow Acceleration Channels. By accelerating the airflow in the critical outer regions of the fan blades, intake-side vortex separation is reduced, resulting in higher efficiency and lower turbulence-related noise emissions.

Noctua’s AAO (Advanced Acoustic Optimisation) frames feature integrated vibration dampers as well as a stepped inlet design and inner surface microstructures, which enable even better performance/noise efficiency.

The anti-vibration pads, made from extra-soft silicone, reduce the transmission of minimal vibrations and are compatible with all standard screws as well as common mounting systems or fan clips used on CPU coolers.

Despite its further improved performance, the power consumption of the NF-A14 ULN is only 0.48W. This means the fan even helps to reduce your electricity bill!

Noctua fans are known for their impeccable quality and outstanding durability. Like all Noctua fans, the NF-A14 has an MTBF specification of over 150,000 hours and comes with a full 6-year manufacturer’s warranty.
