Designed for discerning users and gaming professionals, the Noctua NF-A14 case fan incorporates a host of design innovation and technology to achieve first rate thermal and acoustic performance in your powerhouse. The NF-A14 complies with Noctua’s AAO (Advanced Acoustic Optimisation) standard. It features square shape and 140mm mounting holes (124.5mm spacing) for use on watercooling radiators or as an upgrade for 140mm case fans. The NF-A14 further improves the renowned quiet cooling performance of the award-winning NF-P14 with sophisticated aerodynamic design measures. 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.

  • newegg Succeeding the award-winning NF-P14 Noctua’s NF-P14 fan has become a default-choice among PC enthusiasts looking for a premium quality quiet 140mm fan. Thanks to its thoroughgoing aerodynamic optimisations, the NF-A14 provides higher static pressure and an even better airflow/noise ratio than its much acclaimed predecessor.
  • newegg Cools quietly Noctua’s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua’s unique Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan’s performance/noise efficiency. And the latest version of Noctua’s advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations and switching noises.
  • newegg SSO2 Bearing The NF-A4x10 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.
  • newegg 3 speed settings for full flexibility Providing 1200, 1050 and 900 rpm speed settings via the supplied Low-Noise and Ultra-Low-Noise Adaptors, the NF-A14 FLX (Flexibility) can be fine-tuned for superior airflow or maximum quietness.
  • newegg Extensive Cabling Options The fan’s short 20cm primary cable minimises cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary. Both cables are fully sleeved.
  • newegg Ultra-Low Power Consumption Despite of its further improved performance, the NF-A14 FLX consumes only 0.96W of power, which amounts to a reduction of about 20% as compared to its predecessor. This doesn’t only make it eco-friendly but also helps to cut down the electricity bill!

5 out of 5 eggsSilent Tornado

Pros: Super quiet technology, soft corners for mounting, no vibrations, moves air

Cons: well, it is large but you knew that

Other Thoughts: The larger the fan blades, the more air you can move at low speeds. I use this on the front of my case to draw air in. Keep it connected with the ultra low fan noise cable (low rpm) and it still moves a good amount of air in.

5 out of 5 eggs

Pros: Absolutely Silent with good airflow. comes with rubber attachements to case that can be used for other fans.

Cons: A bit pricy

Other Thoughts: It comes with screws and rubber thingys (i dont know what to call them) that can be used to attach them to the case. Use the Rubber attachments for other fans to reduce friction because the noctua are so quiet that it is overkill to use it on them.
