Product Info

The 90mm PWM Fan on the Pulse of European Styling

featureFeaturing Noctua's AAO frame and sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A9x14 is a highly optimized, premium quality quiet fan in a unique 92 x 92 x 14mm size.

Due to its thickness of only 14mm, the NF-A9x14 is a perfect match for low profile CPU coolers and all other applications that require slimmer fans. Noctua's custom-designed PWM IC for fully automatic speed control and reference class SSO2 bearings guarantee superb running smoothness and excellent long-term stability.

Topped off with modular cabling, a Low-Noise Adaptor and 6 years manufacturer's warranty, the NF-A9x14 is a premium choice for the highest demands.


14mm Low Profile Design
featureMeasuring only 14mm in thickness, the NF-A9x14 is much slimmer than standard 92x25mm fans. This makes it ideal for all applications where standard fans would take up too much space, such as low profile CPU coolers in HTPC builds or server environments.

Flow Acceleration Channels
featureThe NF-A9x14 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.

AAO Frame
featureNoctua's AAO (Advanced Acoustic Optimization) 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.

Stepped Inlet Design
featureNoctua's Stepped Inlet Design adds turbulence to the influx in order to facilitate the transition from laminar flow to turbulent flow, which reduces tonal intake noise, improves flow attachment and increases suction capacity, especially in space restricted environments.

Inner Surface Microstructures
featureWith 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.

Integrated Anti-Vibration Pads
featureIntegrated Anti-Vibration Pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard mounting systems and fan clips used on heatsinks.

SSO2 Bearing
featureThe NF-A9x14 features the further optimized 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 stabilization, precision and durability.

Custom designed PWM IC with SCD
featureSupporting fully automatic PWM speed control, the NF-A9x14 uses Noctua's novel, custom designed NE-FD1 PWM IC that integrates Smooth Commutation Drive (SCD) technology. By providing smoother torque impulses, SCD suppresses PWM switching noises and thus makes the fan quieter at lower speeds.

Dual Low-Noise Adaptors
featureThe NF-A9x14 is supplied with a Low-Noise Adaptor (L.N.A.) that reduces the maximum fan speed from 2,200 to 1,700rpm. The L.N.A can be used either to run the fan at a fixed speed of 1,200rpm or to cap the maximum speed when using automatic PWM control.

Extensive Cabling Options
featureThe fan's short 20cm primary cable minimizes cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary. Both cables are fully sleeved and a 4-pin y-cable allows to connect a second NF-A9x14 fan to the same PWM fan header for automatic control.

6 Year Manufacturer Limited Warranty
featureNoctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-A9x14 features an MTBF of more than 150.000 hours rating and comes with a full 6 years manufacturer's warranty.
