Greater than one weekQuiet. Great air flow. Solid construction. Very good fans. Use them on my CPU radiator and am very satisfied. Who came up with the tan and cinnamon color scheme, I dont know. Quite ugly. But I dont care about that on a radiator. Definitely a best buy. Thinking about replacing all my fans with Noctua products.

> 3 daybought to replace stock fans on H110 GTi radiator on overclocked 6700K, pull configuration. MASSIVE drop in noise from the case, with no increase in temperature. Will be replacing the rest of the cases speakers with these eventually. Not a necessary upgrade, but if you can budget for them theyre fantastic.

> 3 dayBest fans you can buy for your PC without a doubt. Extremely quiet and extremely effective. And extremely ugly.

> 3 dayMy computer was loud, the fans were like 10 years old and just caused a heck of a racket, sounded like an airplane starting up. I replaced all my fans with Noctua (1 x 140mm and 4 x 120mm) and the difference is astounding. There is obviously still sound when i start up the computer, but its considerably less, so much so that we hardly notice its running. Very nice.

Greater than one weekBought two.. Quieter and moves more air than expected. Arrived in a timely manner, only gripe I had was that I had to apply a bit of pressure to the frame of the fan in order to properly install it, though more than likely thats simply a fault of my case and not the fan itself.

> 3 dayThese fans are fantastic. They are very high quality, quiet and powerful. Im using them on an Define R4 so getting enough airflow through mesh and filters in important and these deliver.
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.
