    I am using this fan as a top case intake to feed my my CPU cooler. I have its speed controlled by the CPU temperature. It is very quiet and moves a good amount of air. My idle temps are 1c above ambient and my load temps are as good as open case. It is very quiet even under load. A great fan but a tad expensive.

    Gotta love that hideous brown. Nothing performs better.

    I bought this for an NZXT Source 210 case. I am using it in one of the top fan mounts. I primarily bought this fan because the advanced bearing allows mounting in any orientation with no problems. I was also interested in quiet operation and longevity. You can buy quiet fans with fluid bearings for cheaper or about the same price but honestly, superior cooling with good engineering and reliability is worth the price to me. I keep my computers until they wear out (generally) so expensive fans are not a waste of money for me.

    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!

    I purchased 3 of these fans to replace a few old Corsair fans that were in my case...and although they are only fans, my GPU temps have gone down by about 4-5 degrees and the overall cooling of my system is much better overall now. Solid product with solid results, cant go wrong with these.

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.
