Universal maintenance-free liquid cooling system with a 240 mm channel aluminum radiator, low-noise pump, and a pair of durable 120 mm fans with increased static pressure. The manufacturer claims an ability to remove and dissipate up to 250 W of thermal power from the processor. This enables the system to be used not only with mid-range CPUs but also with flagship top-tier solutions under prolonged high-load conditions.

This efficiency is achieved through the optimization of coolant flow speed and the use of high-performance fans. With the 240 mm radiator size, the be quiet! Pure Loop 3 240 liquid cooling system is compatible with most modern MidTower and FullTower cases that have mounting spaces for a pair of 120-mm fans on the top or front panel. The compact micro-channel copper water block does not interfere with motherboard power subsystem radiators and does not block RAM slots.

The included Pure Wings 3 PWM High-Speed fans have optimized blades and support Feedback Technology, which maintains a stable blade rotation speed regardless of flow resistance, such as when passing through dense radiator fins. The ability to adjust the pump speed from 3000 to 5500 RPM allows for flexible balancing between maximum cooling and complete silence. Enhanced static pressure, compatibility with top-tier CPUs, be quiet! Pure Loop 3 240's innovative design, efficient cooling while maintaining silence, versatile size fitting most cases, pump speed adjustability, and technologically advanced fans make this system stand out.
