Noctua NF-A9x14 PWM 92mm fan

NF-A9x14 PWM fan - 92mm

The NF-A9x14 PWM is a high-optimized, quiet 92x14mm fan in premium quality, which draws on forward-looking aerodynamic design measures such as flow acceleration channels as well as Noctuas AAO frame system. Thanks to a depth of only 14mm, the NF-A9x14 is perfectly suitable for low-profile CPU coolers as well as all other applications, which require thinner fans. Noctuas new PWM IC for fully automatic control and the SSO2 reference class bearing guarantee superb smoothness and excellent long-term stability. Modular cabling and low-noise adapter make the NF-A9x14 a premium solution for the highest demands.

14mm low-profile design
With a depth of only 14mm, the NF-A9x14 is much slimmer than the 92x25mm standard fan. 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.

Flow Acceleration Channels
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 eddy solutions are reduced, resulting in higher efficiency and a lower turbulence-related noise emission.

AAO frame system
Noctuas AAO (Advanced Acoustic Optimization) frames have integrated vibration buffers, a stepped inlet design and an internal surface microstructure (Inner Surface Microstructures) that enable even better performance/noise efficiency.

Quilted inlet design
The stepped inlet area of the Stepped Inlet Design creates more turbulence in the supply. This facilitates the transition from laminar flow to turbulent flow, which is better attached to the frame (flow attachment) and thus increases the suction capacity of the fan, especially with a limited suction area.

Inner Surface Microstructures
The inner surface microstructure (Inner Surface Microstructures) creates a boundary layer through which the tips of the fan blades move. This reduces the current separation from the suction side of the blade tips, resulting in a significant reduction of the rotating tone and an increase in the pressure and air flow efficiency.

Integrated anti-vibration pads
The anti-vibration pads made of extra-soft silicone reduce the transmission of minimal vibrations and are also compatible with all standard screws as well as commercially available mounting systems or fan clamps used in CPU coolers.

SSO2 storage system
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 and thus causes an even better stabilization, which leads to a further improved precision and durability.

PWM IC WITH SCD
The NF-A9x14 PWM supports fully automatic speed control via PWM and uses Noctua's new, specially designed NE-FD1 chip for this purpose. This new PWM IC integrates Noctuas Smooth Commutation Drive (SCD) technology, which minimizes PWM switching noise and makes the fan quieter at low speeds.

Stops at 0% PWM
The fan can be brought to a complete standstill by being controlled by the mainboard or a fan control with a PWM duty cycle of 0%. This makes it ideal for semi-passive systems, which switch off the fans under low thermal load and thus run completely silently.

Low-noise adapter
The NF-A9x14 PWM is delivered with a (L.N.A.), which reduces the maximum speed from 2200 to 1700rpm. This allows you to operate the fan either with constant 1700rpm or limit the maximum speed in PWM operation.

Comprehensive connection options
While the 20cm short primary cable helps to avoid cable mess in typical applications, the included 30cm extension offers extra range for all cases. Both cables are fully sheathed and a 4-pin Y-cable enables a second PWM fan to be controlled at the same connection.
