be quiet! Light Loop 240mm ARGB AIO Liquid CPU Cooler BW020

The be quiet! Light Loop 240mm ARGB AIO Liquid CPU Cooler is an all-in-one water cooling unit designed for users running overclocked or high-end systems who need both strong thermal performance and visual customization. It combines a high-density cold plate, jet plate design, and two Light Wings LX fans with integrated ARGB lighting into a single sealed loop that requires no expertise to install.Why This Product 48 LEDs for customizable system lighting — The cooling block and two fans carry 48 total ARGB LEDs that synchronize via a single header, letting you set colors and effects across your whole cooler from one control point. High cooling power for demanding CPUs — A high-density fin stack cold plate and metal jet plate deliver the thermal capacity needed for modern flagship processors under full load or overclocking. Quiet operation despite high performance — Progressive IC motor technology and 9 airflow-optimized fan blades reduce pump and fan noise to 30.9 dB at maximum speed while maintaining cooling output. Easy refill and long-term durability — An accessible refill port and included coolant bottle let you maintain the loop's performance and lifespan without breaking the seal or draining the system. At a Glance Radiator size 240mm Fans included 2 × Light Wings LX 120mm PWM high-speed Total LEDs 48 ARGB (32 on fans, 16 on block) Maximum fan noise 30.9 dBA Maximum fan speed 2100 rpm Warranty 3 years Compatibility ✓ Works with any modern consumer CPU socket via universal mounting brackets. ✓ ARGB headers synchronize with Asus Aura, MSI Mystic Light, Gigabyte RGB Fusion and other standard motherboard lighting software. ✓ Fits cases with 240mm radiator mounting points (front, top or rear orientation depending on case design). Note: Requires one PWM fan header and one ARGB header on the motherboard, or can use a single header if you bypass the included hub. Best For / Trade-offsBest for: Builders who want visible RGB cooling without buying separate RGB fans. Overclocked or high-end CPU systems that benefit from strong thermal headroom. Users who value quiet operation and low pump noise during gaming or content creation. System builders prioritizing easy maintenance and refill access. Trade-offs: Budget builds where cost is the primary constraint; AIO coolers cost more than air solutions. Cases with only top-mounted radiator space in tight layouts; 52 mm depth (with fans) may conflict with tall memory or chipset coolers. Users who do not want any RGB lighting; the cooler cannot be run with LEDs disabled without disabling the entire ARGB hub. DescriptionLight Loop 240mm Black is an impressively high-performing All-in-One water cooling unit with uniquely illuminated ARGB cooling block for users with overclocked systems.Light Loop 240mm Black features 48 LEDs in total, leading to stunning visuals. Since your PC is not like any other, you can individualize your build with numerous colors and illumination options. The uniquely illuminated cooling block and Light Wings LX fans make Light Loop 240mm Black an undisputed highlight in any system.Light Loop 240mm Black features 2 Light Wings LX 120mm PWM high-speed fans. They come with 16 LEDs that perfectly scatter across the fan blades and are key for the stunning visuals Light Loop 240mm Black offers. The fan's 9 airflow-optimized fan blades not only reduce noise-generating turbulences but also ensure that Light Wings LX 120mm PWM high-speed provides the performance that is needed, even in demanding scenarios.With Light Loop 240mm Black even highly demanding applications can be used reliably. An impressively high cooling power provides low temperatures even during periods of peak CPU performance. Perfectly suited for your next session!Jet plate, pump and the cold plate of Light Loop 240mm Black are designed for peak performance. The metal jet plate increases pressure of the cooling liquid, leading to an enhanced performance. A cold plate with a high-density fin stack increases cooling performance on modern flagship and high-end CPUs. Finally, a progressive IC in the motor reduces switching noise, ensuring the noise of the pump stays at a low level.The ARGB-PWM-Hub enables synchronization of up to 6 PWM fans and 6 ARGB components. This allows you to control all your cooling and lighting gear with just one PWM and one ARGB header on your motherboard. It can be positioned anywhere inside the case with adhesive tape or screw holes that match a 2.5" SSD mounting.The refill port is easy to access which makes refilling safe and comfortable. The coolant bottle included in scope of delivery makes it easy to achieve a long lifespan.SpecificationsFan Brand be quiet!
