Keep your gaming or work PC cool and quiet with the be quiet! Pure Loop 3 LX 360 mm liquid cooler. Designed for top performance and low noise, this cooler combines powerful cooling with a stylish look.
The Pure Loop 3 LX 360 mm features a large 360 mm radiator and three high-speed 120 mm fans to keep even the most demanding CPUs at safe temperatures. The fans use special blades that push air efficiently while staying whisper-quiet, even when your system is working hard.
The pump unit runs smoothly and quietly, thanks to a modern 3-phase motor that reduces vibration. It also has bright ARGB lighting on the pump head, giving your build a customisable glow. You can even swap out the included faceplates to change the design and match your setup’s style.
Installation is easy and works with all major Intel and AMD sockets, including Intel LGA 1700 and AMD AM5. The cooler also includes a refill port, so you can top up the liquid if needed and keep it running strong for years.
Whether you’re gaming, streaming, or creating content, the be quiet! Pure Loop 3 LX 360 mm delivers excellent cooling performance with the near-silent operation the brand is known for.
