The NF-A14 is a quiet 140mm premium fan with a square AAO (Advanced Acoustic Optimization) frame. Its square shape and 140mm mounting holes (124.5mm hole spacing) make it an excellent choice for use on water cooling radiators or as housing fans. Thanks to advanced aerodynamic design measures such as Flow Acceleration Channels, the NF-A14 achieves a further improvement in silent cooling performance compared to the award-winning NF-P14. The FLX version offers three speed settings (1200/1050/900rpm) via the supplied low-noise adapters, thus providing full flexibility between maximum flow rate and almost silent operation. Its superb smoothness, the SSO2 reference class bearing and Noctua's proven premium quality make the NF-A14 FLX a top-of-the-line solution for the highest demands.
Successor to the multiple Test winner NF-P14
Noctuas NF-P14 has become a standard solution for PC enthusiasts who require 140mm premium quality fans. By far-reaching aerodynamic optimizations, the NF-A14 achieves even higher static pressure compared to its well-known predecessor, as well as a further improved ratio of flow rate and noise emission.
Square 140mm frame
With its square frame and 140mm mounting holes (124,5mm hole spacing), the NF-A14 is an ideal premium upgrade for standard 140mm chassis fans. At the same time, it is perfectly suited for use on 140mm water cooling radiators, where the square shape guarantees a complete cover of the cooling fins and thus the best pressure performance.
Flow Acceleration Channels
The impeller of the NF-A14 is equipped with so-called flow acceleration channels at the suction side. The acceleration of the air flow in the critical outer regions of the fan blades reduces the suction-side vortex-ablation, resulting in higher efficiency and lower turbulence-related noise emission.
Integrated Anti-Vibration Pads
The anti-vibration pads, made from extra-soft silicone, reduce the transmission of minimal vibrations while being compatible with all standard mounting systems and fan clips used in CPU coolers.
SSO2 bearings
The NF-A14 is equipped with the further optimized second generation of Noctua's proven SSO storage system. At SSO2, the rear magnet sits closer to the fan axis, resulting in even better stabilization, resulting in further improved precision and durability.
Metal Bearing Shell
In order to guarantee the highest possible degree of manufacturing precision, minimum tolerances and excellent long-term stability, the NF-A14 uses a CNC machined bearing shell made of brass.
Smooth Commutation Drive 2
The latest, further developed version of Noctua's SCD drive system guarantees outstanding smoothness by eliminating torque fluctuations and switching noises. This makes the NF-A14 surprisingly quiet even from close proximity.
