Product information

Description

Silent Wings 4 140mm PWM is a high-performance cooling fan engineered for minimal noise and efficient airflow. It combines a six-pole motor, anti-vibration mountings and fan blades optimized for maximum airflow to meet the needs of demanding high-end systems.

Advantages

The fan delivers near-inaudible operation while maintaining strong airflow and pressure. Anti-vibration mountings reduce transferred vibrations to the chassis, and the 6-pole motor provides stable, reliable rotation. Blade geometry is designed to maximize airflow without significant noise increase, making the fan suitable for cooling radiators, CPU coolers and case ventilation.

Key specifications

Size: 140 mm
Control: PWM
Motor: 6-pole
Anti-vibration mountings: included
Application: radiators, CPU coolers, case ventilation

How to use

Install the Silent Wings 4 140mm PWM in the desired position following your system or cooler manufacturer instructions. Connect the PWM cable to the motherboard or fan controller to enable automatic speed control. Ensure anti-vibration mountings are seated correctly to minimize noise transfer. Check airflow direction markings on the frame before mounting.

Recommendations

For best results, use the fan with PWM-supporting headers to allow automatic speed adjustment based on system temperature. When mounting on radiators, ensure even screw tension and sufficient clearance for optimal airflow.
