Overview

This three-pack of 140mm reverse-blade PWM fans uses a modular pin system to daisy-chain power, PWM, and ARGB signals. They suit builders who want high static pressure for radiators and clean cable routing.

Modular Daisy-Chain Design

Each fan features pin contacts on the frame that transmit power, PWM control, and 5V ARGB data to the next unit. This allows multiple fans to run on a single cable chain, reducing clutter. The central 7-pin connector is detachable to clear radiator thickness, and an included adapter splits the signal for direct motherboard hookup.

Cooling Performance

The fluid dynamic bearing spins between 200 and 1600 RPM while generating up to 71.6 CFM of airflow and 2.95 mmH2O of static pressure. Maximum noise is rated at 28.6 dB(A). The reverse blade orientation pushes air through dense fin stacks, making these fans effective on radiators and heatsinks.

ARGB Lighting System

Forty addressable LEDs are distributed across the rotor hub, two aluminum frame strips, and multiple infinity mirrors that create visual depth. Effects and colors are managed through L-Connect 3 software, which auto-detects connected fans and synchronizes lighting with fan speed curves.

Compatibility and Contents

Fans require Lian Li LULI-039 or LULI-040 controllers for the native daisy-chain ecosystem; they are not compatible with older SL or AL series hardware. The package contains three individual 140mm fans and a 7-pin to motherboard adapter for 4-pin PWM and 3-pin 5V ARGB headers.
