Three-Pack White 120 mm Case Fans

This set includes three 120 mm white case fans with reverse-blade design and integrated ARGB lighting. A dedicated controller is bundled so the fans can be linked together and managed from a single point. The pack is aimed at builders who want coordinated airflow and lighting across multiple intake or exhaust positions in a standard ATX chassis.

Controller and Software Integration

The supplied FLEX Receiver handles power distribution, RPM reporting and lets you choose between motherboard PWM and 5 V 3-pin ARGB sync or L-Connect 3 wireless control. This means fan speeds and light effects can be managed through your motherboard software or the Lian Li app without extra hubs. Existing SL Wireless and CL Wireless fans can also be connected to the same receiver for unified control.

Compatibility Checks Before Ordering

Verify that your case has mounting points for three 120 mm fans in the locations you plan to use. Confirm your motherboard provides a 5 V 3-pin ARGB header and a 4-pin PWM header if you prefer wired control over wireless. Ensure the reverse-blade airflow direction matches your intended intake or exhaust layout, as the blades push air opposite to conventional fans.

Questions about this item

What maintenance will the three white fans and their controller need over time?

The fans use standard 120 mm frames with reverse blades; dust can be cleared with compressed air or a soft brush, and the FLEX receiver has no user-serviceable parts.

What limit appears first when the fans run continuously at high speed?

The PWM signal caps RPM at the motherboard or L-Connect 3 profile you set, so the practical ceiling is the speed curve you choose rather than a fixed hardware limit.

How much noise and heat do the fans add when running all day?

Noise and heat output scale with the PWM duty cycle you select; at lower curves the fans stay quiet and add minimal warmth, while maximum speed increases both proportionally.
