> 3 dayI have had 2 of these fans stop working. One was about 4 years old and the other was about 2 years old. Submitted a RMA for both and never got a response on both.

> 3 dayNoctua fans are among the best. Great airflow while being quiet. However not the prettiest, but easily recognizable

> 3 dayIn a quest for a quieter gaming and media PC I recently spent the cash on a pair of these Noctua NF-A14 FLX fans and a Noctua NF-F12 PWM. I recently upgraded from the Aerocool Dead Silence 140mm fans that were anything but Dead Silent. Now my PC stays cool and from 5 feet away I can’t hear my PC at all. At 3 feet I can only hear the hard drives. Well worth the price if you can live with the brown color scheme.

> 3 dayThe packaging is really nice and makes this fan feel high quality from the start. It’s just a fan, but it’s quiet and moves a lot of air. Not much more you could ask from Noctua.

Greater than one weekBest fan I have ever installed, hands down. For those of us who need quiet fans in production environments, Noctua delivers the best airflow at the fewest dBs. Highly recommend.

> 3 dayReplaced the rear fan in the case with it just for maximum quiet. Works great...very quiet.

> 3 dayThe fan pushes a decent amount of air, even on Ultra Low. My only complaint. are that it is audible on every fan setting. This is mostly due to the mechanical noise coming from the motor. Even on Ultra Low, you can still hear and audible noise coming from just the motor. It sounds like a buzzing sound, that is always going on.

> 3 dayYes, these fans are fugly, my advice is to get over it and look at the performance. Noctua is a high performing fan and its whisper quiet, my rigs temps dropped by a full 11C after switching to 3 top mounted Noctua 120mm and a bottom 140mm compared to my previous fans performance (and which were obnoxiously loud). If I crank the rpms higher I can get another 1-3C temp drop and theyre still significantly quieter than my previous performance fans. Initially noise reduction is why I gave the Noctua a closer look, but after reading several critical reviews of their performance I decided to make the spend and see if it was worth it. Placement of fan and deciding on how you want to set your air pressure/flow is of course a important part of it all, but I was quite literally surprised at how well these performed while being so very quiet in the process.

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 FLX version provides 1200/1050/900rpm speed settings via the supplied Low-Noise Adaptors in order to provide full flexibility in fine-tuning the fan for maximum ventilation performance or near-silent operation. Its superb running smoothness, reference-class SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for the highest demands.
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.
