> 3 dayReplaced rear fan in Cooler Master HAF-932 Improved as its 7 years old. Original was perfectly fine but Noctua is clearly higher premium quality.

> 3 dayThe fan functions as all Noctua fans, Great! You can never go wrong with this brand of computer fan. I would buy again & again.

> 3 dayI tried buying other fans to save a couple dollars, but that only helped me appreciate the value Noctua brings. Solid construction, great performance at every RPM, much quieter than other fans, and comes with useful good quality Y-spliters, extension cable and silicon mounting. I dont even consider these fans to be expensive because theyre worth every cent

> 3 dayNot really a fan of the brown, but having bought several of these for a big case PC, I can confirm that theyre big, theyre quiet, and they move massive amounts of air.

> 3 dayExcellent case fan, tuned for airflow and very quiet, even when running at full speed.

> 3 dayIts a little bit pricey compare to other fans. However, I can justify to spend a few dollars more to get a fan with 3x the life cycle and ultra quite yet powerful performance. I used those fans to replace the stock fans came with the NZXT X61.

> 3 dayGreat fan, good price, and the noise level is excellent. I don’t care that it’s ugly.

> 3 dayHigh quality, quite, and powerful! They are a little louder than the 120mm Noctua fans that I am use to (this is my first pair of 140mm fans). They are still overall quiet compared to other fans that I have had before I discovered Noctua.
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.
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 ChannelsThe 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. |
SSO2 BearingThe 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. |
Integrated anti-vibration padsIntegrated 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. |

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.
