> 24 hourVery 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.

> 24 hourgreat silent fan, mounted in a top case mount to blow cpu heat upwards and out, stopped working within 6 months of install.

> 24 hourLove 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.

> 24 hourVery happy with these fans. Pushes a lot more air then my stock ones. Use them in an air cooled system. Keeps my system cool all year long. I do not care about the color so the brown was fine.

> 24 hourAmazing airflow while staying impressively quiet. The quality of these fans is worth every penny. Using with a Fractal R4 which requires fans with high static pressure. These fans are perfect.

> 24 hourNoctua makes possibly the best fans on the market. I have never had a bad experience with their products and they offer a 6 year warranty on their products. Their customer service is also amazing. Most fans will not last you that long; most fans stop working after 3-4 years if you are lucky. This is the reason you buy these fans because you know they will last you a long time and you always have the warranty as a backup option in case it dies out.

> 24 hourI use this fan on the back of my XT10g GoTo reflector telescope. It moves a lot of air with little to no noise and no noticeable vibration. Once Im sure my scope is cooled I normally turn the fan off to conserve battery power, but do occasionally forget because it is so smooth and quiet.
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. |

AAO frame
Noctua"s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua"s proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan"s performance/noise efficiency.
