Benefiting from the latest technological advances in aerodynamics, including Flow Acceleration Channels, the NF-A14 takes the cooling performance for which the NF-P14 is renowned even further.
Quiet box fan 140mm
 |
Successor to the famous NF-P14
Noctua's NF-P14 fan has become the benchmark in the PC world. Thanks to numerous successive aerodynamic optimisations, the NF-A14 now offers increased static pressure and an even better airflow/noise ratio than its predecessor.
|
 |
140mm square frame
The NF-A14's 140mm square frame has 140mm mounting holes(124.5mm spacing), making it ideal for use with conventional 140mm enclosures or watercooling fans.
|
 |
Flow Acceleration Channels
The NF-A14 impeller is fitted with flow channels on the suction side of the fan. The flow acceleration generated at the tips of the blades creates a more massive, less dispersed suction, thus increasing efficiency.
|
 |
AAO frame
Noctua's AAO(Advanced Acoustic Optimisation) frames are equipped with anti-vibration mounts and benefit from exclusive optimisations to push the limits of performance and silence.
|
 |
Stepped Inlet Design
Noctua's Stepped Inlet design adds turbulence to the inlet flow, allowing a gradual transition from laminar to turbulent flow. This reduces noise emissions, generates a more massive flow and increases suction power.
|
 |
Inner Surface Microstructures
As the blade tips move in a boundary layer influenced by the presence of an Inner Surface Microstructure, the flow separation that takes place at the suction level becomes almost non-existent.
|
 |
Integrated anti-vibration dampers
The integrated anti-vibration mounts, made of extra soft silicone, limit the transmission of vibrations while ensuring perfect compatibility with standard fastening systems.
|
 |
SSO2 Bearing
This is the latest generation of the SSO2 bearing, which is even more optimised. The SSO2 is equipped with a rear magnet closer to the axle for greater precision, durability and stability.
|
 |
Metal bearings
In order to ensure the highest quality of workmanship, durability and stability, the NF-A14 is equipped with a CNC machined brass bearing.
|
 |
Low noise adapter The NF-A14 is supplied with a Low Noise Adaptator (L.N.A.) which reduces the maximum speed from 1500 to 1200rpm. The L.N.A. is suitable for both fixed speed operation (1200rpm) and for use in flanged PWM mode. |
 |
Exclusive PWM IC system with SCD
Compatible with PWM automated speed control systems, the NF-A14s feature the latest NE-FD1 PWM IC which incorporates Smooth Commutation Drive (SCD) technology. By generating less abrupt torque pulses, SCD eliminates the noise associated with PWM switching for quieter fan speeds.
|
 |
Extensive wiring options
The first fan cable is a short 20cm (8") cable to minimise space requirements for common applications. The supplied 30cm extension cable will solve any distance problems.
|
 |
6-year manufacturer's warranty
Noctua fans are renowned for their high quality and long service life. As with all Noctua models, the NF-A14 has an MTBF of over 150,000 test hours and comes with a full 6-year manufacturer's warranty.

Noctua NF-A14: a good reference, but only on paper... Ordered to replace an ageing ANTEC tower fan that was starting to vibrate.
But as soon as I switched it on, I already missed the original fan because of the noise generated by this Noctua.
Perhaps an attenuator to reduce the rotation speed a little would have solved the problem, but this product doesn't have one.
Looking for something really quiet? Skip it ...
6 examples bought at once in 2019 to equip the beast. They haven't moved and are here to stay until I retire. It's Noctua. It's good stuff. Never disappointed.
Quiet and robust. It comes with two types of fastener (screw or rubber fastener) and several types of connector, including a 'Y' connector cable, which can really come in handy when you're short of free pins.
Quiet, powerful, durable, a classic and a sure thing. You can never go wrong with a Noctua fan.
The air intake and exhaust capacity when they are running at 100% is pretty crazy: they are noisy at that speed though, I keep them at about 60% constant. I use them at locker entry and exit.
I bought 5 of these for my Meshify S2 housing. Totally silent. I start to hear them slightly at around 60% charge. I am very happy with them.
In the same universe: noctua | noctua 140
