Reliable cooling power for sophisticated applications

With Pure Loop 2 280mm even the most demanding applications can be used reliably. An immense cooling power provides low temperatures even during periods of peak CPU performance.


Performant, yet quiet operation

2 Pure Wings 3 140mm PWM high-speed fans provide high air pressure to efficiently cool the liquid of the Pure Loop 2 280mm 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 33.8dB(A).


Adjustable and silent operation

The doubly decoupled PWM-pump runs smoothly and silent. Due to the PWM control the pump speed can be adjusted for silent as well as powerful operations. Thanks to the effective damping the pump causes even less noise and minimal vibration. This is the key to provide the well-known silent be quiet! operation.


And a neat design overall

An all-black design in combination with subtle ARGB illumination make for an elegant look. This is further underlined by the aluminum-style cooling block that guarantees Pure Loop 2 280mm looks good in any system.


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.

"The Pure Wings 3 offer a remarkable performance-to-noise ratio, making Pure Loop 2 both impressively performant and yet very quiet. Pure Loop 2 is simply consistent to the end."
