be quiet!, a German manufacturer of premium PC components, has announced the Silent Loop 3, its latest all-in-one (AIO) water cooling series. This series combines high cooling performance, virtually inaudible operation, and advanced technology. The Silent Loop 3 features a powerful pump, Silent Wings 4 fans, an iconic cooling block design with ARGB LEDs, radiator sizes up to 420mm, and an easy-to-access refill port.
Whisper-Quiet Operation

The Silent Loop 3 lives up to the be quiet! reputation. A powerful 6-pole, 3-phase PWM pump with a 3-chamber design ensures high performance at whisper-quiet noise levels. The pump’s second chamber acts as a reservoir, reducing turbulence. The radiator uses up to three Silent Wings 4 PWM high-speed fans with silence-optimized fan blades and a funnel-shaped air outlet. The fan frame design minimizes air leakage, balancing quiet operation and high performance.

Detailed Design for Optimal Cooling

The Silent Loop 3’s cooling block features a unique design. Its 1,800 mm² fin area, up to twice as large as many other AIOs in its class, is achieved through a specially developed screwless design for attaching the heat plate. This design improves heat transfer and ensures complete CPU coverage. All Silent Loop 3 models can efficiently cool processors on current consumer sockets. The 360mm and 420mm models can even cool Threadripper processors (mounting kit included). The all-black cooling block design incorporates discreet ARGB LEDs.

“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,” says Aaron Licht, CEO of be quiet!. “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.”
Easy Refilling and Long Lifespan

Like other be quiet! AIO products, the Silent Loop 3 includes an easy-to-access refill port for convenient maintenance. A cooling bottle is included to extend the unit’s lifespan. Flexible, sleeved tubes simplify installation, even in cases with limited space. All Silent Loop 3 models come with a 3-year manufacturer’s warranty.
