Be Quiet! PURE LOOP 3 360mm – High-Performance Liquid Cooling

The be quiet! PURE LOOP 3 360mm is an all-in-one liquid CPU cooler designed to provide effective cooling for modern desktop processors while combining a large radiator with three 120mm fans. Its 360mm radiator measures 397 × 120 × 27mm, providing a substantial cooling surface for systems equipped with compatible processors. The cooler uses a dedicated pump operating at 3,500 RPM to circulate the cooling liquid through the system, while the three included fans can operate at speeds of up to 2,100 RPM. With ARGB lighting integrated into the design, the PURE LOOP 3 360mm also adds configurable visual illumination to compatible PC builds, making it suitable for gaming systems and performance-focused desktop configurations.

360mm Radiator Design

The PURE LOOP 3 360mm features a large 360mm radiator measuring 397 × 120 × 27mm. The radiator provides a broad surface area for transferring heat away from the circulating coolant, making the cooler suitable for systems where effective CPU thermal management is required. Its 360mm format is designed around three 120mm fans, creating a balanced cooling arrangement across the radiator. The radiator dimensions also provide important information when planning a PC build, as available case space and radiator mounting support should be considered before installation. For users building a performance-oriented system, the combination of a 360mm radiator and three fans provides a substantial liquid-cooling platform while maintaining the integrated design and straightforward installation concept associated with all-in-one CPU coolers.

Triple 120mm Fan Configuration

Cooling airflow across the radiator is provided by three 120mm fans, each capable of reaching speeds of up to 2,100 RPM. The fans use Fluid Dynamic Bearings, a bearing design intended for smooth and reliable fan operation. The three-fan configuration allows airflow to be distributed across the full length of the 360mm radiator, supporting efficient heat transfer from the liquid cooling loop to the surrounding air. Fan speed can reach up to 2,100 RPM when higher airflow is required, while the 120mm format is widely supported by PC cases designed for 360mm radiator installations. This makes the PURE LOOP 3 360mm a suitable cooling solution for performance-focused builds where radiator capacity and multiple-fan airflow are important considerations.

3,500 RPM Pump

The cooling loop is driven by a dedicated 3,500 RPM pump, which circulates coolant between the CPU cooling assembly and the radiator. This integrated liquid-cooling design separates the heat transfer process from the airflow stage, allowing heat collected from the processor to be transported through the coolant before being dissipated through the radiator and its three 120mm fans. The pump speed of 3,500 RPM forms a key part of the PURE LOOP 3 360mm specification and is designed around the cooler's 360mm radiator configuration. Together with the radiator and triple-fan arrangement, the pump provides the circulation required for the all-in-one cooling system to operate as a complete closed cooling solution for compatible Intel and AMD desktop platforms.

ARGB Lighting

The be quiet! PURE LOOP 3 360mm includes ARGB lighting, adding configurable illumination to compatible PC builds. Addressable RGB lighting can be used to complement other illuminated components and create a coordinated appearance inside a gaming or enthusiast system. The ARGB element provides a visual feature alongside the cooler's primary thermal-management function, allowing the cooling hardware to contribute to the overall presentation of the finished PC.
