2025 was a good year for be quiet! and the company continues to release new products, improving its position for AIO coolers, with the introduction of the be quiet! Pure Loop 3 series. In fact, the new product comes with two different versions, with or without RGB.

Pure Loop 3 LX is purpose-built for ARGB enthusiasts and high-performance systems. Its illuminated cooling block offers pre-installed ARGB with 10 interchangeable lighting foils, enabling users to define their system’s look with precision and ease. The foils allow unique and breathtaking lighting visuals without requiring software.

Cooling is handled by two or three Light Wings LX 120mm PWM high-speed fans, each equipped with 16 LEDs and nine airflow-optimized blades. These fans maintain quiet operation through closed loop motor control, keeping fan speed consistent regardless of airflow resistance. A specially designed funnel-shaped air outlet enhances static pressure and cooling efficiency, and a daisy chain function simplifies cabling by allowing the fans to connect in series, reducing clutter inside the case. The powerful 6-pole, 3-phase PWM pump ensures whisper-quiet and vibration-minimized operation at both high and low loads.

Installation and maintenance are effortless thanks to flexible tubing and an easy-to-access refill port, while the cooler’s bold design language delivers both functionality and visual appeal. Pure Loop 3 LX is the ideal solution for showcases with emphasis on lighting, advanced gaming rigs, and demanding multitasking systems. Pure Loop 3 LX is available in two formats: 360mm and 240mm.

For those who value efficiency and discretion, Pure Loop 3 offers impressively high cooling performance in an understated package. Tailored for systems where visual minimalism is key, this cooler excludes lighting entirely, focusing instead on robust performance even under sustained high CPU workloads.

Available in three models (360mm, 280mm, and 240mm), Pure Loop 3 is outfitted with Pure Wings 3 PWM high-speed fans that support a closed loop motor function and daisy chaining for a cleaner installation. Despite their strong aerodynamics and static pressure, Pure Wings 3 fans maintain maximum noise levels of only 36.8 dB(A), ensuring systems stay quiet even under stress.

Pure Loop 3 also includes flexible tubing, a refill port for long-term operation, and an elegant cooling block design that emphasizes precision engineering. It is perfectly suited for overclocked systems, advanced gaming PCs, and high-resolution multimedia builds.

Pure Loop 3 LX and Pure Loop 3 models will be available from September 9 at the following suggested retail prices; all coolers are backed by a 3-year manufacturer’s warranty.

With Pure Loop 3 280mm even the most demanding applications can be used reliably. An immense cooling power provides low temperatures even during periods of peak CPU performance.

A powerful PWM pump ensures the very high-performance of Pure Loop 3 280mm and is whisper-quiet at the same time. The 6-pole 3-phase motor provides a smooth and consequently silent operation, whether at high or low rpm.

2 Pure Wings 3 140mm PWM high-speed fans provide high air pressure to efficiently cool the liquid of the Pure Loop 3 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 36,6dB(A).

If you want to connect more fans than your system has headers for, you are in for a problem. A 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 280mm allows all fans to be connected in series. We provide fewer and shorter cables to help you achieve a cleaner look.

Pure Loop 3 280mm is the perfect choice for all purists that do not want to bother with lighting effects in their systems. However, this AiO shines even without lighting: the cooling block features an unmistakable design that gives Pure Loop 3 280mm a premium touch. A clear visual upgrade for any system.
