Keep your CPU cool and your PC looking great with the be quiet! Pure Loop 3 LX 240 mm liquid cooler. Designed for strong performance and near-silent operation, this cooler is ideal for gamers, content creators, and anyone who wants reliable cooling without extra noise.
The Pure Loop 3 LX 240 mm includes a 240 mm radiator and two high-performance Light Wings LX 120 mm fans with bright ARGB lighting, giving your system smooth airflow and a customisable look. Both the fans and the pump are engineered to run quietly, even when your system is under heavy load.
It also features a refill port, allowing you to easily top up the liquid and extend the cooler’s lifespan — something most other all-in-one coolers don’t offer. The sturdy build, sleeved tubes, and secure mounting system make installation straightforward and durable.
Compatible with the latest Intel and AMD sockets (including LGA 1851, 1700, 1200, and AM5/AM4), the Pure Loop 3 LX 240 mm is ready for modern and future processors.
