    Lovely fan. Quiet+great airflow. I bought 3 for my lancool k60 but Im thinking to buy two more.

    I use this fan as an exhaust on my PC, and is does a very good job. The fan is not silent when running at full speed, but Noctua includes two adapters to lower the RPM, which also lowers the noise. All necessary parts are included for installation, including some tool less silicone pull-through mounts, which are great, and an extension for the fan connector. All the cables are sleeved. Noctua spends a lot of time designing their products, and it shows.

    The best fans that you can get for quite operation they are best for radiators and large heat sinks and make good air flow fans when

    The airflow is superb coming from the fan which cools my components more better then my prior case fans.The fan is also quiet which is a double bonus. Totally worth the purchase!

    I wanted to build a dead silent PC for listening to music with an open headphone. I also leave my PC on during the night right next to me as I use it to run some programs that take a while. I decided to purchase two of these fans and place them in the front of my Fractal R5 case. At the lowest speed fan setting, I cannot hear ANY sound coming out of the case. None. The temperature of the CPU and GPU stay below 60 degrees Celsius at the lowest speed fan setting, which means I wont even know whether the computer is turned on or not unless I look at the monitor screen.

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

    I heard so many great things about Noctua fans and decided to give them a try. Everything that is said about them is 100% true, these are greats fans! In the box you get the fan (obviously!), extension cable, 2 low noise adapters, and rubber mounting screws. Moves plenty of air while staying whisper quiet. A tad on the expensive side but well worth the cash. After all, you get what you pay for!

    Loving how quiet this fan is. Bought one as an intake fan for my NZXT Source 530. Install wasnt as bad as people say. Just yank on those little rubber anti-vibrating pegs and the fan will be secure. It is very quiet and Im pleased with it so far.

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 Channels

The 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 Bearing

The 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 pads

Integrated 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.
