be quiet! Light Loop 240mm AIO Liquid CPU Cooler

The be quiet! Light Loop 240mm (BW020) delivers high-performance liquid cooling for overclocked systems with vibrant ARGB illumination. This all-in-one water cooling solution combines efficient heat dissipation with quiet operation and extensive RGB customization options.

Cooling Performance

The 240mm aluminum radiator features a high-density fin stack optimized for heat dissipation. Two Light Wings LX 120mm PWM high-speed fans deliver 61.8 CFM airflow at 2100 RPM, providing effective cooling for demanding CPUs. The copper base with nickel plating ensures optimal thermal transfer, while the included thermal grease simplifies installation.

ARGB Lighting System

The cooling block features multiple illumination zones creating striking visual effects. The included ARGB-PWM hub synchronizes up to 6 ARGB components and PWM fans through a single 3-pin 5V addressable connector, streamlining cable management and lighting control.

Quiet Operation

The state-of-the-art pump operates at 2900 RPM with progressive IC technology for minimal noise. Adjustable from 1500-2900 RPM via 4-pin PWM, the pump adapts to cooling demands. Fan noise levels range from 15.4 dB(A) at 50% to 34.9 dB(A) at maximum speed, maintaining quiet operation even under load.

Maintenance and Compatibility

The easy-access refill port and included 100ml coolant bottle enable straightforward maintenance. Compatible with Intel 1851, 1700, 1200, 1150, 1151, 1155 and AMD AM5, AM4 sockets. The 400mm tube length provides flexible installation options in various case configurations.
