Be quiet! Pure Loop 3 280mm
The Be quiet! Pure Loop 3 280 mm liquid cooler is a complete, closed-loop set that efficiently dissipates heat from the processor in high-performance systems. This AIO liquid cooler combines impressive cooling performance with exceptionally quiet operation, making it ideal for overclocked systems and demanding applications. Thanks to its 280mm radiator and two Pure Wings 3 PWM high-speed fans, it maintains low temperatures even under heavy loads. Be quiet! designed this CPU cooler with an emphasis on simple installation, long-term reliability, and easy maintenance via an accessible refill port. The overall design optimises the balance between performance and noise, which will be especially appreciated by builders of quiet and powerful PCs.

Pump design
The cooling system uses a PWM pump with a 6-pole motor, which reduces vibrations and noise. The pump operates at speeds ranging from 3000 to 5500 RPM, ensuring smooth and quiet operation. Its high cooling performance can handle even the most demanding processors and maintains low temperatures under heavy loads. The pump's design actively reduces turbulence and fluid noise within the circuit.
Pure Wings 3 fans
Two Pure Wings 3 140mm PWM high-speed fans dissipate heat from the 280mm aluminium radiator. These fans generate high static pressure and feature a closed-loop motor. This technology maintains a stable speed regardless of air resistance, making it optimal for radiators. Even at 1800 RPM, operation remains very quiet thanks to the optimised blade shape.
Refill port on the radiator
Flexible, braided 400mm tubes simplify installation. The fans support daisy-chaining, which reduces the number of cables and makes organising them inside the case easier. An easily accessible refill port on the radiator is used for topping up the coolant, which enables simple maintenance, extending the lifespan and maintaining the performance of the system.
Look and craftsmanship
The Pure Loop 3 280 mm has a simple design. This approach targets users who prefer a functional and unobtrusive look for their PC build. The manufacturer has finished the entire system in black, from the braided tubes to the radiator. The CPU cooler block has a specific design with subtle details, ensuring a clean and professional appearance. It is suitable for workstations or gaming rigs where the emphasis is on performance and silence.
