Case fan Lian Li UF-RSLIN140-1W 140 mm RGB — 140 mm RGB cooling fan

The Lian Li UF-RSLIN140-1W is a 140 mm case fan with RGB lighting designed for PC cooling. It fits standard 140 mm mounting locations in computer cases and radiators and provides airflow to help maintain component temperatures while offering multi-colour LED illumination for customizable appearance.

Advantages

The fan combines a compact 140 mm form factor with a fluid dynamic bearing for reduced noise and longer life. It delivers up to 71.6 cfm of airflow and operates at low noise levels (approximately 28.6 dB at high speed), while built-in RGB LEDs offer multi-colour illumination. The white frame and blade design integrate with light-coloured builds.

Ensure airflow direction is correct for intake or exhaust placement and that cables are routed to avoid contact with the blades.

Recommendations

For quieter operation, configure fan speed control via PWM or motherboard fan curves and consider mounting the fan with anti-vibration pads. When using RGB, connect to a compatible controller or motherboard RGB header to synchronize lighting effects.
