High-performance AIO for overclocked CPUs

The be quiet! Light Loop IO LCD 240mm White is an all-in-one liquid cooler built for overclocked systems. It combines a 240mm radiator with an integrated IPS display and intense ARGB lighting. An included IO Controller enables software management of the display and lighting effects. Daisy-chained fans simplify the internal cabling of the build.

Silent cooling with advanced pump control

Silence-optimised fan blades and a progressive IC pump controller deliver high cooling performance with whisper-quiet operation. The specially designed jet plate and cold plate improve heat transfer from the CPU. Flexible sleeved tubes and convenient mounting hardware make installation straightforward. The unit handles thermal loads from consumer processors effectively.

Customisable IPS display and ARGB control

The advanced IPS display shows system information, videos or images with extensive customisation options. ARGB lighting presets and individual adjustments are managed through IO Center for Windows. Two daisy-chained Light Wings LX PWM high-speed fans with funnel-shaped outlets provide vibrant airflow. The bundled controller centralises all lighting and display functions.

Questions about this item

How do I install the 240mm radiator and avoid the common mistake with the daisy-chained fans?

Mount the 240mm radiator in your case, attach the two daisy-chained Light Wings LX PWM high-speed fans, then connect the single PWM lead and ARGB cable to the included IO Controller for software control via IO Center.

What maintenance or replacement will the liquid cooler need later?

The sealed loop requires no refilling; only the two Light Wings LX PWM fans may need replacement after extended use, and the flexible sleeved tubes should be inspected occasionally for kinks or wear.

What limit appears first under sustained heavy load?

The 240mm radiator surface area and dual-fan airflow set the thermal ceiling; the progressive IC pump regulates speed to maintain whisper-quiet operation before hitting that limit.
