Premium 240mm All-in-One Liquid CPU Cooler

The be quiet! Silent Loop 3 240mm delivers exceptional cooling performance for high-performance CPUs including Intel Core i9 and AMD Ryzen 9 series. This premium AIO water cooling solution combines advanced thermal technology with near-silent operation, making it ideal for demanding systems that require efficient heat dissipation without noise compromise.

Advanced 3-Chamber Pump Technology

The innovative 3-chamber pump design minimizes turbulence and operational noise while maximizing cooling efficiency. Featuring a dampened, adjustable 6-pole motor with speeds ranging from 1,700 to 3,500 RPM, the pump ensures smooth, quiet performance even under heavy thermal loads. The cooling block's substantial 1,800 mm² fin area provides comprehensive coverage of CPU hotspots with superior heat transfer capabilities.

Silent Wings 4 High-Speed Fans

Two Silent Wings 4 120mm PWM high-speed fans deliver up to 76.7 CFM airflow while maintaining near-inaudible operation. Optimized for high static pressure up to 3.96 mmH2O, these fans feature Fluid Dynamic Bearings (FDB) with an impressive 300,000-hour MTTF. Operating up to 2,500 RPM with noise levels reaching only 36.9 dB(A), they provide efficient radiator cooling without disrupting your workspace.

Discreet ARGB Lighting

The cooling block features subtle addressable RGB lighting controlled via standard 3-pin 5V connectors, allowing seamless integration with your motherboard's lighting ecosystem for customizable illumination that matches your system aesthetics.

User-Friendly Maintenance Design

An accessible refill port and included coolant bottle ensure easy maintenance and prolonged lifespan. The 400mm flexible sleeved rubber tubing with bend protection provides installation flexibility while maintaining durability.

Universal Socket Compatibility

Compatible with Intel sockets 1851, 1700, 1200, 1150, 1151, and 1155, plus AMD AM5, AM4, TR5, and TR4 (bracket included). The aluminum radiator measures 274 x 120 x 27 mm, fitting standard 240mm mounting locations.
