be quiet! Light Loop IO LCD 240mm Black AIO Liquid Cooler
The be quiet! Light Loop IO LCD 240mm Black is an all-in-one liquid cooler designed for high-performance and overclocked systems. It combines efficient cooling with a 2.1-inch IPS display and RGB lighting, letting you monitor CPU and coolant temperatures, fan speeds, and custom content while maintaining whisper-quiet operation.
Why this product
2.1-inch IPS display with 480×480 resolution
Shows CPU temperatures, coolant temperatures, fan speeds, images, videos and customizable presets. 500 nits brightness ensures visibility even in bright environments.
Whisper-quiet cooling with precision engineering
Jet plate accelerates coolant flow, high-density cold plate maximizes heat dissipation, and advanced pump IC minimizes switching noise. Operates at 17.2 dB(A) at 50% fan speed.
Two daisy-chained Light Wings LX fans
Each 120mm fan has 16 LEDs, 9 airflow-optimized blades, and reaches 2100 RPM max. Fan cables route along the tubes, reducing cable clutter.
Single IO Controller simplifies setup
One cable connects the cooler, fans, ARGB and display signals to a single controller, eliminating the need for multiple connections to the motherboard.
IO Center software for full customization
Windows application lets you adjust display content, lighting effects, fan profiles and monitor system status in real time.

Best for
- High-end gaming and overclocked systems
- Builders who want system monitoring built into the cooler
- Users prioritizing low noise during normal operation
- RGB and lighting enthusiasts with display customization needs
Trade-offs
- Non-Windows systems — IO Center software is Windows-only, limiting display and lighting control on Linux or macOS builds
- Compact cases — 277 mm radiator height and 52 mm depth require adequate space; cooling block is 63.8 × 61.9 mm
- Silent-focused builds at maximum load — reaches 36.8 dB(A) at 100% fan speed for demanding overclocked systems
- Minimal cable management priority — requires connection to an IO Controller unit in addition to standard power connectors
Light Loop IO LCD 240mm Black is an impressively high-performing All-in-One water cooler featuring an IPS display and RGB lighting, designed for overclocked systems.
The Light Loop IO LCD 240mm Black has an eye-catching cooling unit with a progressive round IPS display and RGB lighting. With a size of 2.1 inches, a high-resolution display and a display brightness of 500 nits, there are as many customization options as there are unique ways to display information. Whether it's CPU temperatures, coolant temperatures, fan speeds, images, videos, a wide range of presets and much, much more, your CPU cooler will definitely stand out!
Jet plate, pump, and cold plate of the Light Loop IO LCD 240mm Black are engineered for optimal performance at a whisper-quiet noise level. The precision-engineered metal jet plate accelerates cooling liquid flow velocity, delivering superior efficiency. Featuring a high-density fin stack design, the cold plate maximizes heat dissipation for today's flagship and high-performance CPUs. An advanced integrated circuit within the motor minimizes switching noise, ensuring whisper-quiet pump operation.
The setup includes 2 daisy-chained Light Wings LX PWM high-speed fans. Each fan features 16 LEDs that are perfectly distributed across the blades and are key to the stunning visuals the Light Loop IO LCD 240mm Black offers. The fan's 9 airflow-optimized fan blades not only reduce noise-generating turbulences but also ensure that Light Wings LX PWM high-speed fans provide the performance that is needed, even in demanding scenarios.
Our newly included IO Controller transmits the signal and power to the all-in-one water cooler with just a single cable, allowing for control of the ARGB, PWM and display signals all in one place. In addition, the fan cables are now hidden along the tubes. So, with the Light Loop IO LCD 240mm Black, no additional cables need to be laid from the daisy-chained fans to the mainboard or to a fan hub!
The IO Center for Windows offers many excellent options for customizing the IPS display and lighting of the Light Loop IO LCD 240mm Black. To optimize the water-cooling experience, background effects and the sensor data shown on the display can be adjusted, the lighting of the pump head and fans can be configured, fan profiles can be set up, and the system status can be monitored.
