Overview

A 140mm PWM fan built for CPU coolers, featuring liquid crystal polymer blades and a self-stabilizing oil-pressure bearing for quiet, high-pressure airflow.

Design and Materials

The chromax.black finish provides an all-black frame and rotor suitable for any build aesthetic. Fan blades are molded from liquid crystal polymer, a material chosen for its rigidity and vibration-damping properties. The 25mm thick frame uses standard 105mm mounting hole spacing.

Performance and Acoustics

SupraTorque technology tunes the motor for high static pressure on restrictive heatsinks, reaching 2.56 mmH2O at 1500 RPM. Maximum airflow is 91.58 CFM. Acoustic output peaks at 24.8 dB(A), while the included low-noise adapter caps speed at 1250 RPM for 19.7 dB(A) operation.

Bearing and Control

The SSO2 bearing uses a self-stabilizing oil-pressure design to minimize wobble and harmonic oscillation. A 4-pin PWM connector allows automatic speed control from 0 to 1500 RPM with a 7V starting voltage.

Included Accessories

The package contains a low-noise adapter for quieter operation, a 4-pin PWM Y-splitter for running two fans from one header, and standard mounting screws for 140mm installations.
