> 3 dayPurchased two in December of 2014 to replace two loud dieing radiator fans. First one died maybe 8 months in (just stopped spinning). The second died 4/15/2016 (jerks like it wants to start spinning but wont, no matter what speed the motherboard sets for it). Replacing the fans is a huge pain, which is why I spent the money on these supposedly high quality fans. Maybe I just got a bad batch it happens to the best of companies, that said I wont be purchasing any more.

> 3 dayI am not a fan of these...fans. Do a quick google search of this product and you will see that Nactua has moved production to China and as a result this particular model does not live up to the brands reputation. Yes there are youtubers saying they tested these and there is no difference between the Taiwan versions and Chinas. The proof is in the product. Noctua has based there reputation on quality and performance. These fans are not worth the price that they are selling for. At a certain RPM (1,100ish) they oscillate and cause an audible hum which sends vibration through my PC case. I RMAd one of three fans that I purchased thinking that I got a lemon, the replacement is exactly the same. I put my Phanteks back in the PC and have no issues whatsoever. I have to mention that I also have two Noctua NF-F12s on my radiator and have no complaints with them at all. But as for the NF-A14s I would recommend looking elsewhere.

> 3 dayBought two of these bad boys to replace the absolute unmitigated garbage stock Corsair fans that came on the 280mm radiator of my h110i cooler, which produced a grinding noise even when set on quiet profile. Holy crap are they quiet! I had heard these fans were the best and I am not disappointed!

> 3 dayEven though these are the made in China variant these fans are still the most quiet fans I have had in a computer. When I was making a new build I decided on both these fans for intake and a Noctua cpu cooler and I have to say they made a loyal buyer at of me. As long as they keep up with this quality and proformance I think Ill be using their fans and coolers for a long 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. |
