Overview

This 140mm PWM fan delivers quiet cooling at 24.6 dB(A) with a square frame suited for radiators and cases. It includes six sets of colored anti-vibration pads for build customization.

Design and Compatibility

The square 140mm frame matches standard 140mm mounting holes spaced at 124.5mm. This geometry ensures full coverage on 140mm radiators and fits typical case fan locations. The all-black chromax finish suits monochrome or accent-themed builds.

Acoustic and Airflow Performance

Flow Acceleration Channels on the impeller reduce flow separation and vortex noise. The AAO frame adds Stepped Inlet Design and Inner Surface Microstructures to lower tonal intake noise and improve pressure efficiency. Maximum output reaches 140.2 m³/h at 24.6 dB(A).

Bearing and Motor Control

The second-generation SSO2 bearing places the rear magnet closer to the axis for better stabilization. A CNC-milled brass shell ensures tight tolerances. The custom NE-FD1 PWM IC integrates Smooth Commutation Drive to suppress switching noise at low speeds.

Customization and Accessories

The package includes four anti-vibration pads each in black, white, red, blue, green, and yellow. A fully sleeved black 30cm NA-EC1 cable is pre-installed. Colored cables, y-cables, and anti-vibration mounts are sold separately for further coordination.
