Overview

A 40x20mm 5V PWM fan built for tight spaces requiring quiet, reliable airflow. Suited for small form factor builds, network gear, and industrial 5V applications.

Design and Build

The fan uses a beige and brown 40x20mm frame with an AAO structure and Flow Acceleration Channels to improve airflow efficiency. Modular cabling allows clean routing in compact enclosures.

Performance

At 5000 RPM the fan delivers 9.4 m³/h of airflow and 2.26 mmH2O of static pressure while generating only 14.9 dB(A). The SSO2 bearing and Smooth Commutation Drive ensure consistent, low-vibration operation over time.

Connectivity and Accessories

A 3-pin 5V connector powers the unit. The package includes the OmniJoin adapter set for flexible mounting and cable management options.
