Noctua NF-A12x25-ULN
Noctua NF-A12x25-ULN
The Noctua NF-A12x25 ULN fan is a 120mm model based on the NF-A12x25 design. It uses an AAO (Advanced Acoustic Optimisation) frame and a 0.5mm gap between the blades and the frame, achieving efficient airflow with low noise. The blades are made from Sterrox LCP material, and the metal-reinforced motor hub and precision axle contribute to stable operation, durability, and a long fan lifespan. The fan is suitable for use in computer cases, on CPU coolers, or on water-cooling radiators where low noise and stable performance are required.
Key features of the NOCTUA NF-A12x25-ULN PC fan
- Extremely quiet operation with a smooth acoustic profile
- Sterrox LCP material for high strength and minimal thermal expansion
- AAO frame with integrated anti-vibration pads for stable operation
- Precision SSO2 bearing for long life and stability
- Metal-reinforced motor hub for maximum precision
- Dual-speed mode for individual noise adjustment
- Radiator and cooler compatibility thanks to a silicone sealing gasket
Design and technical solution
The NF-A12x25 ULN model uses aerodynamic features such as Flow Acceleration Channels, a Stepped Inlet Design and Inner Surface Microstructures, which improve airflow and reduce noise and turbulence. The frame with integrated silicone anti-vibration pads limits the transfer of vibrations to surrounding components. The brass bearing and SSO2 system increase rotational precision and reliability during long-term operation.
Quiet operation and features
The fan offers two rotation speeds, 900 and 1200 RPM, which can be changed using the supplied adapter. Smooth Commutation Drive 2 technology ensures smooth operation without speed fluctuations or distracting noises. The package includes an extension cable, an adapter for direct power supply, and a silicone gasket for installation on water coolers.
