be quiet! Light Loop 240mm White AIO Liquid CPU Cooler BW021
The be quiet! Light Loop 240mm White AIO Liquid CPU Cooler is an all-in-one water cooler built for modern high-end CPUs and overclocked systems. It combines ARGB lighting with quiet operation through custom fans and a progressive pump, and includes refillable coolant to extend lifespan.
Why this product
48 LEDs with synchronized ARGB control
The cooling block and Light Wings fans feature 48 LEDs total that can be customized across numerous colors and patterns. The included ARGB-PWM hub synchronizes up to 6 ARGB components and 6 PWM fans from a single motherboard header.
Designed for flagship CPUs and overclocking
It handles Intel Core i9 and AMD Ryzen 9 series with room for overclocking, thanks to a jet plate that increases coolant flow speed and a high-density fin cold plate.
Quiet operation across all speeds
The pump uses a progressive IC to reduce switching noise, and the 9 blade design of the Light Wings fans minimizes turbulence. Noise runs from 15.4 dB at 50% speed to 34.9 dB at full power.
Refillable coolant system
An easy-to-access refill port and included coolant bottle let you maintain the cooler and extend its working life beyond standard sealed units.

Best for
- White-themed PC builds
- Users wanting synchronized ARGB lighting across multiple cooling components
- Overclocked Intel or AMD high-end systems that need reliable cooling
- Builds where quiet operation matters even under heavy load
Trade-offs
- Older socket CPUs — supports only current-generation Intel and AMD platforms
- Compact cases — requires 277 × 120 × 27 mm radiator space and 400 mm tube length
- Builders without RGB control preference — the 48 LEDs and hub add complexity if lighting is not desired
Light Loop 240mm White 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 White is ready for modern flagship CPUs like Intel's Core i9 or AMD's Ryzen 9 series, with room for overclocking.
TRUE COLORS — Unrivalled ARGB lighting
Light Loop 240mm White 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 White fans make Light Loop 240mm White an undisputed highlight in any system.
LIGHT WINGS LX FANS — Performant, yet quiet operation
Light Loop 240mm White features 2 Light Wings LX 120mm PWM high-speed White fans. They come with 16 LEDs that perfectly scatter across the fan blades and are key for the stunning visuals Light Loop 240mm White offers. The fans' 9 airflow-optimized fan blades not only reduce noise-generating turbulences but also ensure that Light Wings LX 120mm PWM high-speed White provides the performance that is needed, even in demanding scenarios.
IMPRESSIVELY HIGH COOLING PERFORMANCE — Designed for intensive gaming sessions
With Light Loop 240mm White 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!
ADVANCED TECHNOLOGIES — One step ahead in every aspect
Jet plate, pump and the cold plate of Light Loop 240mm White are designed for peak performance. The metal jet plate increases flow speed 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.
ONE HUB, MANY POSSIBILITIES — Synchronization of up to 6 ARGB-components
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.
EASY TO REFILL — For a long lifespan
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.
WHITE BEAUTY — Stunning design
Light Loop 240mm White complements all-white systems best, thanks to its uniform white aesthetics. The integrated ARGB LED lighting within the cooling block and fans allows the vibrant lighting to take center stage.
