The be quiet! Pure Loop 3 240mm is a high-performance all-in-one (AIO) liquid cooler designed for effective CPU cooling with minimal noise. Featuring a robust aluminum radiator (277 x 120 x 27 mm) paired with two Pure Wings 3 120mm PWM fans, it delivers up to 59.6 CFM airflow and 2.41 mmH2O static pressure. The copper base plate ensures optimal heat transfer, while the decoupled PWM pump (3000-5500 RPM) operates quietly at the tube end for flexibility in case installations.

This cooler supports a wide range of modern sockets including Intel LGA1851, LGA1700, LGA1200, LGA115x series, and AMD AM4/AM5, making it ideal for Ryzen 9000 and Intel Core i9 processors. With 40cm sleeved tubing, refill port for maintenance, and daisy-chain fan connectivity, it offers user-friendly installation and longevity. No RGB lighting keeps the design clean and focused on silence (15.4-35.2 dB).
