> 3 daySold by AnaMax (USA) but fulfilled by Amazon. I honestly couldnt tell the difference, product shipped extremely quickly considering the lack of direct sales of certain Noctua products at the time I ordered. Price was acceptable (all Noctua products are high quality and high priced) but I didnt see any evidence of an aftermarket markup or value add where no value is added. All in all a great experience. The fans themselves are what I expected from Noctua, having read many reviews and watched countless YouTube videos (lets just admit that theyre showcases and not reviews in most cases on YouTube.)

> 3 dayNoctua never fails to disappoint with their NF-A14 case fans. Runs extremely slow and extremely quite in addition to the anti-vibration rubber fan mounts that come pre-packaged with the unit, its an unstoppable combination. As a person whos big on case acoustics, this fan is perfect for anyone who wants a near silent build. I Highly recommend this product!

Greater than one weekGreat fans and versatile mounting hardware. Run 3 of these in my case and the temps went way down from my previous setup.

Greater than one weekYou get what you pay for and Noctua case fans are no exception. Quite simply these are the best fans you can buy. Great noise to cfm ratio, these fans are ultra quiet and still move quite a bit of air. Great accessories package included. The anti-vibration mounts actually hold the fans snugly to the case as opposed to some other brands with similar systems that I found to very loosely hold their fans. Overall Im impressed but not surprised as Noctua has a reputation for making excellent products. If youre looking for case fans or rad fans these are definitely the best choice.

> 3 dayThe fans are dead slient at 7V & even with adapters at 9V, only wish it was producing less noise at 12 V.

> 3 dayLove these, great quality, nice and quiet if you set the PWM correctly. The silent rubber pin mounts are a little difficult to install though, but I saw no need for them since the corners of the fans have rubber bumpers on them to prevent vibration. I just put the included screws through them instead of the rubber pins.

> 3 dayVery quiet, no whining sound. Bigger size moves more air. Isolated mounts keep motor from vibrating the cabinet..Different power inserts run fan at three different speeds.I run it at 12 volts and it is quiet. Of course you have to enlarge the opening if youre replacing a 120mm fan.
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.

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. |
