Be quiet! Light Loop IO LCD ARGB 240mm CPU Liquid Cooler (2x 120mm PWM fans, LCD display, IO ecosystem, Intel & AMD, Black)

Be quiet! Light Loop IO LCD ARGB — a high-performance liquid cooler

Insufficient cooling for overclocked processors can lead to system instability and reduced performance. The Be quiet! Light Loop IO LCD ARGB 240mm liquid cooler is designed for those who demand quiet, efficient cooling combined with a modern design. Thanks to a 2.1" IPS display with 500-nit brightness, it can display temperatures, fan speeds, and even custom graphic effects—all in a clear and stylish manner. The included IO controller centralizes the management of lighting, fan operation, and the display, ensuring easy installation and tidy cable management. This cooler is compatible with both Intel and AMD systems, and its flexible 400 mm tubing makes it ideal for a wide range of case sizes.

Powerful Cooling and Low Noise

The be quiet! Light Loop IO LCD ARGB features two Light Wings LX 120 mm PWM fans. Thanks to aerodynamically optimized blades and 16 LEDs per fan, they deliver not only excellent airflow of up to 61.8 CFM (105.1 m³/h) but also impressive RGB effects. Noise levels are kept to a minimum—ranging from 15.4 dB(A) at 50% speed to a maximum of 34.9 dB(A) at full speed. An advanced pump with adjustable speeds between 2000 and 2900 RPM ensures efficient cooling with minimal vibration and noise.

IPS Display and IO Center Software

The round 2.1" IPS display features 500-nit brightness, ensuring excellent readability under various lighting conditions. The display allows you to monitor CPU temperature, cooling performance, and fan speeds, or customize the look with your own images and videos. All display, fan, and lighting settings are managed via the IO Center for Windows software, with saved effects uploadable directly to the cooler—eliminating the need for the software to run continuously.

Installation and Compatibility

This cooler is compatible with Intel sockets 1851 / 1700 / 1200 / 1151 / 1150 / 1155 and AMD sockets AM5 / AM4, ensuring broad support for modern processors. An aluminum radiator measuring 277 × 120 × 52 mm (including fans) and a cooling block featuring a nickel-plated copper base contribute to efficient heat dissipation. Flexible, braided 400 mm tubing facilitates installation, even in larger cases. ### Technical Specifications
