Featuring Noctuaâ€™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 92x14mm 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. Noctuaâ€™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 manufacturerâ€™s warranty, the NF-A9x14 is a premium choice for the highest demands.
14mm Low Profile Design
Measuring 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 environment
Flow Acceleration Channels
The NF-A14 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.
Noctuaâ€™s A4O (Advanced Acoustic Optimization) frames feature integrated anti-vibration pads as well as Noctuaâ€™s proprietary stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fanâ€™s performance/noise efficiency.
Steeped Inlet Design
Noctuaâ€™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.
Fan Size 92 x 92 x 14mm
