Features
The NF-A14 is a premium quality quiet 140mm fan with a square frame that complies with Noctua's AAO (Advanced Acoustic Optimisation) standard. Its square shape and 140mm mounting holes (124.5mm spacing) make it ideal for use on watercooling 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 PWM version sports Noctua's custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise-Adaptor to reduce the maximum speed during PWM control from 1500rpm to 1200rpm. Its performance-oriented 1500rpm top speed and comprehensive speed control options make the NF-A14 PWM an elite choice for users who strive to strike a perfect balance between excellent cooling capacity and superb quietness of operation, be it on watercooling radiators, on heatsinks or in case ventilation.
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 optimisations, 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.
AAO frame
Noctua's AAO (Advanced Acoustic Optimisation) 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 ploughing 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 pads
Integrated anti-vibration pads made from extra-soft silicone minimise 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 optimised 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 stabilisation, 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.
Custom-designed PWM IC with SCD
Supporting fully automatic PWM speed control, the NF-A14 PWM uses Noctua's novel, custom-designed NE-FD1 PWM IC that integrates Smooth Commutation Drive (SCD) technology. By providing smoother torque impulses, SCD suppresses PWM switching noises and thus makes the fan quieter at low speeds.
Stops at 0% PWM
When the fan is set to 0% PWM duty cycle by the motherboard or PWM fan controller, it will stop. This makes it ideal for creating setups with semi-passive cooling that automatically turn the fans off and thus run completely silent at idle if thermals allow.
Low-Noise Adaptor
The NF-A14 PWM is supplied with a (L.N.A.) that reduces the maximum fan speed from 1500 to 1200rpm. The L.N.A. can be used either to run the fan at a fixed speed of 1200rpm or to cap the maximum speed when using automatic PWM control.
Extensive cabling options
The fan's short 20cm primary cable minimises cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary. Both cables are fully sleeved and a 4-pin y-cable allows the connection of a second NF-A14 PWM fan to the same PWM fan header for automatic control.

Best quiet fan out there
There is an industrial version but this gets the job done in keeping my 3070 and 5800x running cool. Added 2 noctua fans to my case stock fans and can't be any more happier.
Quiet, great airflow. Solid product

Chromax black swap.
Trusted Noctua brand.
Good accessories.
The price is worth it.
Cons -
None
What more can you ask?
Excellent fans for price
Good noise to airflow ratio
Great performer
Great combo of static pressure and airflow from this fan. Relative silence is a great bonus. Worth the high price.
Noctua is worth it
Way quieter than other fans, definitely worth the higher price.
extra flow for cooler
got this to add to the Noctua NH-U14S TR4 SP3 and had no problems attaching it. Perfect for what i needed.
Better than average, great at medium and low RPM
Noctua makes great fans, not the absolute best - but always above average.
Ideal range is 30 to 50% speed I think, sounds a bit like a jet engine at max speed.
Quiet and impressive
Bought 2 of this fan to replace my Lian Li Lancool 207 case 140mm front stock intake fans and noticed the difference immediately soon as I switched it on! Note that I wasn’t able to use the screw from the stock fans as the stock fans are thicker than the NF-A14, but luckily the case came with spare screws and they fit perfectly well, so shots to Lian Li for that one too!
Nice and Quiet
Made a huge difference compared to my old stock fans.
Cool
Nicely designed fan.
This fan really 'blows'
Very good, Popped in an nzxt h1 and it's very quiet
