> 3 dayUse these as case fans for my nearly silent tower build with a Fractal Design R4. They work as advertised, however I would have optd for the PWM fans since I did not have enough fan controller ports to connect these to.

> 3 dayNo joke. As far as fans go this one is rather expensive. I will say that it is quality. Rubber isolated corners, very quiet, good mounting hardware. I am hoping to get 10 years out of this one. Only time will tell but if I can get 3-5 years out of a cheap fan this one should do better.

> 3 dayPut two of these on top of my c70 for exhaust. They run smooth and quiet and I believe they look nice. Will always go to noctua for fans and cpu coolers because of there quality.

> 3 dayI have a Fractal Design Define R4 Black Pearl case, and I tried upgrading the stock fans with the Fractal Design Dynamic GP-14 Black Case Fans, and still wasnt getting the airflow I wanted. I decided to give these Noctua fans a try, bought one new one from Amazon, and three used ones from a local computer repair shop. Awesome airflow through the case now, temps overall are down 5 degrees C, and Im not hearing any loud fan noise. My system is being used as an entertainment computer, connected to my home theater setup, and from my listening position Im hearing zero fan noise. Im running two of the fans at 7 volts, using the fan controller on the R4 case, and two running at 1150 RPMs using the Scythe SCKMPN-3100 Fan Controller, and I couldnt ask for a quieter machine for home entertainment.

> 3 dayScenario i am a cool freak. I live where its 120f atleast 10 days out of the year. my liquid cooler was doing a good job but the fans included sound like a dying jet and thats not good since they are only 2 weeks old. i replaced every fan in the machine with Noctua fans and its so quiet now and to temp dropped about 4c keeping me in at 52c under 100% load across all 8 cores after running PRIME 95 for 48 hours
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. |

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.
