be quiet! Pure Loop 3 240mm AIO Liquid CPU Cooler BW027

The be quiet! Pure Loop 3 240mm AIO Liquid CPU Cooler is a high-performance all-in-one water cooling system designed for users with moderately overclocked CPUs who want powerful cooling with minimal noise. It combines a capable PWM pump with two Pure Wings 3 fans and flexible tubing for straightforward installation and maintenance.Why This Product Very high cooling performance — The system is engineered to handle demanding workloads and peak CPU performance, keeping temperatures low even during intensive applications. Quiet operation across all speeds — Even at maximum fan speed the system operates at only 35.2 dB(A). The PWM pump is designed to be whisper-quiet while maintaining high performance. Daisy-chained fans reduce cable clutter — All fans connect in series to a single motherboard header, eliminating the need for a separate fan hub and simplifying cable management. Easy refilling and maintenance — An accessible refill port allows convenient top-ups if needed. Flexible sleeved tubes and simple mounting make installation straightforward.

Very high cooling power provides low temperatures even during periods of peak CPU performance.SUPERIOR PUMP DESIGNWith state-of-the-art technologyA powerful PWM pump ensures the very high-performance of Pure Loop 3 240mm and is whisper-quiet at the same time.PURE WINGS 3 FANSA match made in heaven2 Pure Wings 3 120mm PWM high-speed fans provide high air pressure to efficiently cool the liquid of the Pure Loop 3 240mm radiator. The fans also come with a "closed loop motor" function. This feature always keeps a steady fan speed, no matter the resistance – ideal for radiators. Despite their performance, Pure Wings 3 offer very quiet operation. Even at maximum speed, the fans operate at only 35.2dB(A).DAISY CHAINNo need for a fan hubA water cooling system with a pump and 2 fans on top of the case fans can hit the maximum available on a motherboard easily. The daisy chain function of Pure Loop 3 240mm allows all fans to be connected in series. We provide fewer and shorter cables to help you achieve a cleaner look.EASY AND INTUITIVE HANDLINGPure Loop 3 240mm features flexible tubes, so installing it becomes a breeze. The refill port is easily accessible, making refilling this AiO an easy task, if and when it is required.SpecificationsFan Fan model Pure Wings 3 120mm PWM high-speed Number of fans 2 Maximum speed 2100 rpm Airflow at 100% PWM 101.2 m³/h Air pressure at 100% PWM 2.41 mm H₂O Noise level at 50% / 75% / 100% rpm 15.4 / 27.3 / 35.2 dB(A) Bearing technology Rifle Connector 4-pin PWM Performance Radiator dimensions 277 × 120 × 27 mm Radiator material Aluminum Base material Copper Pump speed 5500 rpm Pump adjustable speed range 3000–5500 rpm Pump connector 4-pin PWM Tube length 400 mm Acoustics & power Fan input power 5.4 W Fan rated voltage 12 V Fan input current 0.13 A Lifespan at 25°C 80,000 hours Physical & installation Brand be quiet!
