Description

The be quiet! PURE LOOP 3 is an all-in-one liquid cooler with a 120 mm fan and a compact 12 cm radiator. It provides airflow up to 101.2 m³/h (59.6 cfm) and a maximum static pressure of 2.41 mmH2O, while keeping noise levels low. The unit has a slim profile with a height of 52 mm, a black finish, and supports a wide range of CPU sockets for Intel and AMD systems.

How to use

Install the radiator and 120 mm fan in your case according to the case manufacturer’s mounting options and the cooler’s manual.
