Noctua has a standard box and a standard two-piece plastic shell that protects each of its premium fans. The plastic covers are visible from the fronts of the boxes, as you can see in the bottom picture of page 1 of this review. Close the covers and you can see a consistent front view that tells you exactly what kind of fan is inside.

These boxes fold out to show you the fans, their accessories and their features.


Each fan comes with its own specific set of accessories. The accessories may be standard, but the choice is customised for each fan:
NF-A4x10 5V: 3:2 Pin Adaptor, OmniJoin Adaptor Set, 30cm Extension Cable, 4 Vibration-Compensators and 4 Fan Screws.
NF-A8 ULN: Ultra-Low-Noise Adaptor (U.L.N.A.), 3:4-Pin Adaptor, 30cm Extension Cable, 4 Vibration-Compensators and 4 Fan Screws.
NF-A8 FLX: Low-Noise Adaptor (L.N.A.), Ultra-Low-Noise Adaptor (U.L.N.A.), 3:4-Pin Adaptor, 30cm Extension Cable, 4 Vibration-Compensators and 4 Fan Screws.
NF-A8 PWM: Low-Noise Adaptor (L.N.A.), 4-Pin Y-Cable, 30cm Extension Cable, 4 Vibration-Compensators and 4 Fan Screws.
NF-A9 FLX: Low-Noise Adaptor (L.N.A.), Ultra-Low-Noise Adaptor (U.L.N.A.), 3:4-Pin Adaptor, 30cm Extension Cable, 4 Vibration-Compensators and 4 Fan Screws.
NF-A9 PWM: Low-Noise Adaptor (L.N.A.), 4-Pin Y-Cable, 30cm Extension Cable, 4 Vibration-Compensators, 4 Fan Screws.
All come with the standard Noctua 6-year warranty and their world-class customer service. And each fan features an AAO frame for (Advanced Acoustic Optimisation), Flow Acceleration Channels to reduce suction side flow separation, and “inner surface microstructures.” Noctua says
The only drawback is literally a shortcoming: the vibration absorbers that come with these fans do not protrude through the entire frame; you cannot grab them and pull them through.

With the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency.
The only drawback is literally a shortcoming: the vibration absorbers that come with these fans do not protrude through the entire frame; you cannot grab them and pull them through.
