Noctua NF-A9x14 PWM fan - 92mm [NF-A9x14 PWM]

Thanks to a depth of just 14mm, the NF-A9x14 is perfect for low-profile CPU coolers and all other applications that require thinner fans. Noctua's innovative PWM IC for fully automatic control and the SSO2 reference class bearing guarantee super smooth running and excellent long-term stability. Modular cabling, low-noise adapters and a 6-year manufacturer's warranty make the NF-A9x14 a premium solution for the highest demands.

With a depth of just 14mm, the NF-A9x14 is significantly slimmer than 92 x 25mm standard fans. This makes it ideal for all applications where there is not enough space for standard fans, such as low-profile CPU coolers in HTPCs or server environments. The impeller of the NF-A9x14 is equipped with so-called flow acceleration channels on the suction side. By accelerating the airflow in the critical outer regions of the fan blades, suction-side vortex shedding is reduced, resulting in higher efficiency and lower turbulence-related noise emissions.

Noctua's AAO (Advanced Acoustic Optimization) frames have integrated vibration buffers as well as a stepped inlet area (Stepped Inlet Design) and an inner surface microstructures that enable even better performance/noise efficiency. The stepped inlet area of the stepped inlet design creates more turbulence in the inlet. This facilitates the transition from laminar to turbulent flow, which adheres better to the frame (flow attachment) and thus increases the suction capacity of the fan, especially when the intake area is limited.

The microstructure inside the frame (Inner Surface Microstructures) creates a boundary layer through which the tips of the fan blades move. This reduces flow separation from the suction side of the blade tips, resulting in a significant reduction in rotating noise and an increase in pressure and airflow efficiency. The anti-vibration pads made of extra-soft silicone reduce the transmission of minimal vibrations and are at the same time compatible with all standard screws as well as commercially available mounting systems or fan clips used in CPU coolers.

The NF-A9x14 is equipped with the further optimized second generation of Noctua's proven SSO storage system. With SSO2, the rear magnet sits closer to the fan axis, providing even better stabilization, resulting in further improved precision and durability. The NF-A9x14 PWM supports fully automatic speed control via PWM and uses Noctua's new, specially designed NE-FD1 chip. This new PWM IC integrates Noctua's Smooth Commutation Drive (SCD) technology, which minimizes PWM switching noise and makes the fan even quieter at low speeds

The NF-A9x14 PWM comes with a low-noise adapter (L.N.A.) that reduces the maximum speed from 2200 to 1700rpm. This allows you to either operate the fan at a constant 1700rpm or limit the maximum speed in PWM operation. While the 20cm short primary cable helps to avoid cable tangles in typical applications, the included 30cm extension offers extra reach for all cases. Both cables are fully sheathed and a 4-pin Y-cable makes it possible to control a second PWM fan on the same connection.

Noctua's fans are known for their impeccable quality and outstanding durability. Like all Noctua fans, the NF-A9x14 PWM has an MTBF specification of over 150,000 hours and comes with a full 6-year manufacturer's warranty.
