Overview

A 120mm 5V PWM fan designed for quiet cooling in cases, heatsinks, and radiators. It runs at 450 to 1900 RPM with a maximum noise level of 21.4 dB(A).

Aerodynamic Design

The impeller uses Sterrox liquid-crystal polymer for high tensile strength and low thermal expansion. Flow Acceleration Channels on the suction side reduce flow separation and vortex noise. A 0.5mm tip clearance minimizes leak flows, improving efficiency against back pressure on heatsinks and radiators.

Acoustic Optimization

The AAO frame integrates anti-vibration pads, Stepped Inlet Design, and Inner Surface Microstructures. These features reduce tonal intake noise, suppress blade passing noise, and create a smooth frequency profile. The included Low-Noise Adaptor lowers the maximum speed to 1700 RPM for quieter operation.

Motor and Bearing

The SSO2 bearing places the rear magnet closer to the axis for better stabilization and durability. The motor hub is constructed from steel with a brass-reinforced axle mount, ensuring precision and stability at all speeds.

Accessories and Compatibility

The package includes a 4-pin PWM connector for automatic speed control, a Low-Noise Adaptor, a silicone gasket for radiator sealing, anti-vibration pads, and standard mounting screws. The fan uses a 5V PWM signal and is not suitable for standard motherboard headers.
