Overview

A pair of black 140mm PWM fans using magnetic levitation bearings for quiet operation up to 1700 RPM. Designed for high static pressure on radiators or strong airflow as case fans.

Design and Bearing

Each fan measures 140 x 140 x 25 mm with a black frame and rotor. The magnetic dome bearing minimizes friction to lower noise and extend service life. Maximum noise reaches 36 dB(A) at full speed.

Performance

Fans operate between 330 and 1700 RPM. They deliver up to 95.5 CFM airflow and 3.46 mmH2O static pressure, making them effective for both radiator and case mounting. Blade geometry and Airguide technology optimize flow in either role.

Connectivity and Control

Standard 4-pin PWM connectors allow motherboard speed control. Fans can be daisy-chained together so only one header is required. PWM regulation reduces power draw during low-load situations.

Package Contents

The set includes two RS140 fans. No RGB lighting is present. Weight for the pair is approximately 293 grams.
