be quiet! is proud to introduce Silent Loop 3. This all-in-one water-cooling series represents its passion for technological innovations, all packed up in one AiO. With a powerful pump to ensure an immensely high cooling performance, Silent Wings 4 fans with closed fan frames to maximize air-pressure, an iconic cooling block design with ARGB LEDs, radiator sizes up to 420mm, and an easy-to-access refill port, Silent Loop 3 can be considered a love letter to German engineering.

Virtually inaudible operation – period!
Silent Loop 3 lives up to the “be quiet!” brand name: a powerful 6-pole, 3-phase PWM pump with 3-chamber design ensures high-performance at whisper-quite noise levels. The second of the three chambers acts as a reservoir and offers space for the coolant to spread out, thus reducing turbulences before the liquid leaves the pump unit. And it’s not just the pump that’s silent: the radiator features up to three Silent Wings 4 PWM high-speed fans with silence-optimized fan blades and a funnel-shaped air outlet. The corners of the fan frame are designed to minimize air leakage, resulting in a perfect balance between quiet operation and the highest performance.
Obsession with details

The cooling block of Silent Loop 3 is unique in design and elegant in appearance. The block boasts an 1,800 mm² fin area, which is an increase of up to 2x compared to many other AiO’s in this class. Such a large fin area is achieved by a specially developed screwless design for attaching the heat plate, resulting in a greatly improved heat transfer and making sure all hot spots on the CPU are covered. All three Silent Loop 3 models are able to effortlessly cool all processors on current consumer sockets; Silent Loop 3 360mm and Silent Loop 3 420mm even allow cooling of Threadripper processors (mounting kit included). To represent the sheer cooling power of Silent Loop 3, the cooling block design is all-black, with discreet ARGB LEDs for a unique look.

"With Silent Loop 3, we’ve pushed our engineering even further to create an AiO cooler that delivers top-tier performance while staying impressively silent. The powerful pump, optimized cooling block, and our high-pressure Silent Wings 4 fans work together to keep even high-end processors cool with minimal noise. Every detail is designed for efficiency, durability, and ease of use, making Silent Loop 3 the perfect choice for anyone who wants quiet high-performance liquid cooling," says Aaron Licht, CEO of be quiet!.
Simplified refilling process for a long lifespan

As always, with be quiet! AiO products, Silent Loop 3 features an easy-to-access refill port that makes for convenient handling, safe refilling and comfortable maintenance. A cooling bottle is included to extend the lifespan of the water-cooling unit. Flexible, premium sleeved tubes enable simple and flexible installation even in cases with limited space. All Silent Loop 3 models come with a 3-year manufacturer’s warranty.

Silent Loop 3 will be available for sale from February 25 at the suggested retail price of $174.90/€174.90/£124.99 (420mm), $164.90/€164.90/£119.99 (360mm), and $139.90/€139.90/£99.99 (240mm).
