> 3 daymy case is now silent thanks to these fans. replaced all 3 Antec P101 silent 120mm and 140mm case fans, with 3 of these, connected to PWM connectors on the motherboard. sure, theyre more expensive but worth every penny. the extension cables are a life savor and i couldnt finish the install without them

Greater than one weekVery nice fans, used to replace Corsair fans on my H110GTXi. Much quieter and move plenty of air. Im thinking about replacing some of my case fans with more of these.

Greater than one weekAlways a great buy with high performance and quality. Comes with a lot of cable extras that allow easy routing back to a fan hub. Cpu dropped 8 degrees after updating from generic case fans.

> 3 dayBought this to replace a 140mm exhaust fan on my case that was starting to make noises. Noctua is so quiet, and those mounts are great for isolating vibration. Expensive: yes. But they are really well built and super quiet.

> 3 dayIve been using Amazon for over a decade and this is the first review Ive ever written. These fans are AMAZING. I have a CPU radiator (Corsair H100i GTX) and the noise from the stock fans were driving me insane. I cannot believe I lived with it for over 2 years before I discovered these fans. Seriously. Do not doubt...These fans do exactly what they advertise!

> 3 dayGreat fan. Included anti vibration mounts are a pain to install in limited space.

> 3 dayTheyre decent, but if installed in pull config the blades will sag after a few years and start rubbing on your radiator. They could use to sit a few mm higher.

04-06-2025I have three of these in my Corsair 550D build: two surrounding a 140mm Kraken X40 radiator and one on the 550D side panel. All three installed trouble-free, and the noise reduction from the stock fans on the Corsair case is tremendous.
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.
