> 3 dayI really wish Noctua would make all black fans. These bad boys are amazing. I absolutely hate the colour scheme. But they push so much are, and make so little noise; it is simply astonishing. The 140mm are quieter and more powerful than the 120mm - I think they should be the new standard but thats just me.

Greater than one weekThese are no doubt the best fans available. The quality is amazing. Holding other fans in your hands against the Noctua fans is jaw dropping. From now on, every case fan will be the Noctua fans. These fans come with everything and then some. Evening the packaging is amazing. I got rid of water cooling on this last build and I went with their CPU Cooler. No more water cooling for me and taking a chance on leaks and cracks.

> 3 dayThis is a must own fan for people who water cool their components due to the static pressure of the fans. I wouldnt recommend spending this much money on just a case fan, but for a radiator fan this is the fan to beat.

> 3 dayBought 5 of these fans total. Used them to replaced the three stock fans in my Corsair 750D case and then add two more exhaust fans at the top.

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. |
