Two 140mm fans with ARGB and controller

This pack includes two 140mm case fans finished in white with addressable RGB lighting. A dedicated controller is supplied to manage the fans and their lighting from a single point. The fans are 25mm thick and designed for standard case mounting locations.

Builders who want daisy-chained ARGB cooling

The bundle suits builders who prefer a simple, cable-reduced setup with synchronised white ARGB illumination across two 140mm fans. It is not intended for users who need higher static pressure for dense radiators or who require more than two fans without buying additional packs.

140mm diameter with 25mm thickness

The 140mm frame and 25mm depth determine whether the fans fit your case mounting points and clear surrounding components. Verify the available space in your chassis before purchase.

Questions about this item

How do the 140 mm fans clip together and connect to the supplied controller without loose cables?

Each fan has interlocking side rails and a single internal connector; slide the second unit onto the first until the rails click, then plug the lead into the controller’s port — missing the click leaves the signal wire unseated.

What part of the ARGB lighting or bearing will need attention after long running hours?

The addressable LEDs are rated for the fan’s lifetime, so only the fluid-dynamic bearing may eventually require replacement if noise rises after several years of continuous use.

At what point does the 25 mm thick frame hit its airflow limit during sustained high-RPM operation?

When static pressure exceeds what the 25 mm blade geometry can push through dense radiator fins or stacked dust filters, RPM climbs without extra flow — that is the practical ceiling.
