The be quiet! Light Loop 240mm is an all-in-one liquid cooling solution designed for systems that require efficient heat dissipation, including those with overclocked processors. Its thermal performance is derived from a 2900 RPM pump, a 240mm aluminum radiator, and a nickel-plated copper cold plate, a combination engineered to effectively transfer heat from the CPU. The unit's 400mm sleeved rubber tubing provides adequate length and flexibility for installation in a variety of mid-tower and full-tower computer cases.
This cooler is equipped with two 120mm fans that utilize Pulse Width Modulation (PWM) to adjust speeds between 1500 and 2100 RPM, which allows for a balance between airflow and noise output based on system load. Both the fans and the pump block feature addressable RGB illumination for visual customization, connecting via a standard 3-pin 5V header. An included ARGB-PWM hub enables centralized control and synchronization of both lighting effects and fan speeds for up to six compatible devices.
