Corsair iCue is a software tool from the manufacturer Corsair used to manage, control, and synchronize various computer components of this brand. In the context of a computer case, it primarily involves the customization of built-in RGB lighting and the regulation of fan speeds. "RGB lighting" is a technology that uses diodes mixing red, green, and blue colors to display millions of color shades and various lighting effects. Through the iCue program, users can set the colors their case will glow with, choose dynamic effects, or synchronize the lighting with other components. In addition to lighting, the software also allows for adjusting fan speeds to find a balance between efficient cooling and quiet operation. For this control to work, iCue-supported cases include a control unit to which the fans and light strips are connected, which then communicates with the software. The entire system thus unifies the control of multiple elements into a single application.
