> 3 dayBrand speaks for itself, this is my first Noctua buy, and they definitely met all expectations and hype surrounding their fans. Buy this one if you dont want the even more amazing (and better looking) 3000 rpm industrial version, or just want all the awesome accessories this comes with (extension cable, y cable, low noise adapter, anti-vibration mounts). I just got two 120mm industrial ones, and now wish this 140mm Im using as rear exhaust was a 3000 rpm capable monster as well! Although, I ended up needing the extension cable from this fan on one of the industrial 120 mm fans...guess I could have just bought the extension cable :) o well, Ill wait for this one to die (probably never) or just give it to a friend when I upgrade again.

> 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. |
