The be quiet! Silent Loop 3 240mm is an all-in-one liquid cooling system engineered for low-noise operation and high thermal efficiency. Its design incorporates a three-chamber pump with a 6-pole motor that operates at up to 3500 RPM, working to reduce turbulence and operational noise within the cooling loop. This pump is paired with a 240mm aluminum radiator and two Silent Wings 4 120mm PWM fans. The fans are designed to deliver high static pressure, which promotes effective heat dissipation from the radiator fins.
This cooler utilizes a copper base plate for direct thermal transfer from the processor. Its 400mm tubes are sleeved for durability and present a clean aesthetic within a system build. For visual customization, the pump block is equipped with addressable RGB illumination, compatible with standard 3-pin ARGB motherboard headers. A notable maintenance feature is the integrated refill port, which allows for topping up the coolant. The system includes all necessary mounting hardware for installation on current Intel and AMD sockets.
