> 3 dayI thought the fan was too expensive at first, but changed my mind after installing it to my Define R4 and seeing quite a significant drop in temperature on my pc. Highly recommended!

> 3 dayI have 2 of the PMWs on my hyper 212 and they have worked great so I thought I would get a 140mm for the front of my case.. Worked great for about 2 weeks then when I was cleaning out dust I noticed a brown substance around the shroud and traced it back to the bearing leaking lol... Im sure it was a fluke and this isnt normal but keep a look out guys.. Amazon is great for returns...

> 3 dayI dont remember if I bought the 2 NF-A14 FLX fans here or some where else, so I thought I would go ahead and post a review on both sites that I deal with for my electronics.

> 3 dayGreat fans, I put six of these in my Fractal Designs R4 and they are quieter than the three Fractal 140mm fans they replaced. Top quality fans that are well worth the money.

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. |
