Noctua NF-A14 ULN Fan, SSO2 Bearing, 140mm, Brown/Beige

The NF-A14 ULN is a 140mm cooling component engineered for ultra-low noise operations in desktop PC systems. This unit features a maximum rotational speed of 800 RPM, optimized to achieve an air volume flow rate of 79.8 m³/h (46.97 CFM). Static pressure registers at 0.69 mmH₂O, indicating suitability for deployment as either case ventilation or on less restrictive radiator assemblies. The frame and blades are constructed from PBT GF30 material, prioritizing structural integrity and minimized resonance.

Acoustic performance is rated at 11.9 dB at full speed, dropping to 9.1 dB when utilizing the included Low-Noise Adaptor (LNA), which limits the speed to 650 RPM. The fan utilizes the proprietary SSO2 bearing system, a specialized self-stabilizing oil-pressure technology designed to ensure precise operational stability and a long mean time to failure (MTTF) of 150,000 hours. Connectivity is managed via a standard 3-pin connector operating at 12V. The component package includes silicone anti-vibration pads and various cables for flexible installation within different chassis configurations.
