Be quiet! Pure Loop 3 LX 360mm

The Be quiet! Pure Loop 3 LX 360mm liquid cooler is the ideal cooling solution for high-performance processors. This system uses a closed-loop water circuit with a 360mm radiator, which effectively cools even processors with a high thermal output. The Be quiet! Pure Loop 3 LX system combines high cooling performance with dynamic lighting and the quiet operation typical of the brand. The set includes three Light Wings LX fans, an adjustable PWM pump and ARGB backlighting that you can customise individually. The product is designed and quality-controlled in Germany, with an emphasis on reliability for demanding gaming and professional builds.

ARGB lighting

The cooling block with its integrated pump features addressable ARGB lighting, which you can easily customise. The package includes ten interchangeable foils that you can insert under the block's top cover. Each foil changes the colour rendering and style of the lighting effects, opening up a wide range of possibilities for visual coordination with other components in your build. The foils are mechanically simple to change and require no tools. This ARGB liquid cooling therefore offers customisation from subtle single-colour backlighting to dynamic rainbow effects.

Powerful fans

Three Light Wings LX PWM fans take care of dissipating heat from the aluminium radiator. These fans have an optimised nine-blade design for higher airflow and suppression of unwanted turbulence, which contributes to their quiet operation. Thanks to PWM control, they operate automatically at speeds of up to 2100RPM. Rifle-type bearings give them long-term operational reliability. Furthermore, the closed-loop motor maintains a constant speed regardless of air resistance, which is key for effectively blowing air through the radiator's dense fin stack.

Quiet and adjustable PWM pump

The cooling circuit is driven by a pump integrated into the cooling block, controlled by a PWM signal in the 3000 to 5500RPM range. This control enables the system to automatically adjust its performance to the current processor load. The pump uses a 6-pole, three-phase motor for smooth, low-vibration operation. This design limits operating noise and contributes to the quiet performance of the entire cooling system. As a result, the cooling maintains a low acoustic footprint even at high performance.

Easy installation

Flexible braided hoses with a length of 400 millimetres make it easy to install the cooler in various computer cases. For a cleaner build appearance and simpler cable management, the system supports daisy-chaining the fans. This feature connects the fans to each other, and a single cable connects them to the motherboard for both PWM and ARGB. The circuit comes factory-filled and ready for immediate use. For long-term maintenance, an easily accessible refill port is provided on the radiator for topping up the coolant if needed.
