> 3 dayBought these fans to reduce noise in my system and was not disappointed. Compared to old fans, these are whisper quiet at full load, unnoticeable at regular loads.

Greater than one weekI replaced my stock case fans. Not only are these much quieter, but the air flow is significantly greater. Noctua continues to satisfy.

01-06-2025I 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 dayThese fans have top notch performance. I used two in the past for a push/pull setup on a small AIO and they went with it when a friend of mine inherited the build. Now I have two more as intake fans for my new air cooler build.

> 3 dayI bought a couple of these to replace the noisy broken potato fans that came with my nzxt x61 kraken water cooler. They are a bit pricey, but they are near silent, unless you have them really ramped up like around 70-80% load, and perform much better than I expected. I dont really have anything else to say besides that these are most likely one of, if not the best, static pressure oriented fans on the market. They definitely wont match your system color unless youve gone with a desert theme, so if youre willing to sacrifice aethstetics for some fantastic air pushers, these are the heat sink fans for you

Greater than one weekI installed this fan for top cooling of a homebuilt AMD Ryzen 5 PC. I have another smaller Noctua fan installed on the CPU cooler. I settled on Noctua after cheaper brands became noisy over time.
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.
