Product information

Description

Three Light Wings 140mm PWM case fans provide impressive ARGB illumination combined with efficient cooling. Designed to deliver strong airflow and quiet operation, these 140mm PWM fans balance lighting effects with thermal performance for PC builds that require both visual impact and reliable cooling.

Advantages

These Light Wings 140mm PWM fans offer vibrant ARGB lighting visible from multiple angles, steady PWM control for optimized speed and noise levels, and a design focused on efficient airflow and cooling. They are suitable for systems where low noise and consistent illumination are important.

Key specifications

Form factor: 140 mm
Control: PWM (pulse-width modulation)
Lighting: ARGB illumination
Function: Case fan for airflow and cooling

How to use

Install the fans in your PC case using the supplied mounting screws, orienting them for intake or exhaust according to your airflow plan. Connect the PWM power cable to a compatible motherboard header for speed control and connect the ARGB cable to an addressable RGB header or compatible controller to manage lighting effects. Adjust fan curves in BIOS or software for the desired balance of cooling and noise.

Recommendations

For best results, combine these 140mm PWM Light Wings fans with a well-planned case airflow setup and configure PWM curves to keep noise low while maintaining sufficient cooling. Ensure your motherboard or controller supports ARGB headers for full lighting control.
