The be quiet! Pure Loop 3 280mm is an all-in-one liquid CPU cooler for PC builders who want strong, quiet cooling for demanding workloads, gaming or an overclocked system. Its 280mm radiator and two 140mm fans suit builds with space for a larger radiator and support a range of current and previous Intel and AMD sockets.

A PWM pump with a 6-pole motor is designed to reduce vibration while circulating coolant through the radiator. The two Pure Wings 3 high-speed fans provide high air pressure and can be daisy-chained, helping simplify fan connections and cable routing. Flexible sleeved tubes make installation easier, and an accessible refill port supports maintenance when required. The cooler has no lighting effects, keeping the design understated.

Key features

• All-in-one liquid cooling designed for consumer CPUs, including systems under demanding loads.
• PWM pump with a 6-pole motor for smooth operation with reduced vibration.
• Two Pure Wings 3 140mm PWM high-speed fans provide airflow and static pressure for the radiator.
• Daisy-chain fan connections help reduce cable clutter and avoid needing a separate fan hub for the supplied fans.
• Flexible sleeved tubes support easier positioning during installation.
• Accessible refill port makes coolant maintenance more convenient when needed.
• Unlit cooling block design for systems without lighting effects.

Compatibility

Supports Intel LGA 1851, 1700, 1200, 1151, 1150 and 1155, and AMD AM5 and AM4 sockets. Check that your case has room for a 317 x 140 x 52mm radiator assembly, including fans, and that the mounting hardware suits your socket. Good to know: this cooler requires a compatible motherboard socket and case radiator space; confirm both before ordering.
