Pure Loop 2 360mm all-in-one cooler

The be quiet! Pure Loop 2 360mm is a 360 mm all-in-one liquid cooler built for CPUs that demand strong heat dissipation. It supports AMD Socket AM4, AM5 and Intel LGA 1150, 1151, 1155, 1200 and 1700 platforms. Three 120 mm Pure Wings 3 PWM fans and a doubly decoupled PWM pump deliver high static pressure in a compact loop. An integrated refill port and included coolant bottle extend service life for enthusiasts who maintain their own systems. Builders needing a smaller radiator or air-cooling simplicity should look elsewhere.

Thermals noise and power in normal use

Three Pure Wings 3 120 mm PWM high-speed fans push air through the 360 mm radiator while peaking at only 36.8 dB(A) at maximum speed. The closed-loop motor function keeps fan speed steady regardless of radiator resistance, providing consistent airflow during typical workloads. The doubly decoupled PWM pump reduces vibrations to a minimum and adjusts speed via PWM for quiet operation at idle and light loads. Together the pump and fans maintain low coolant temperatures without audible distraction in everyday desktop use.

Behaviour under sustained load

Under prolonged heavy CPU loads the 360 mm radiator surface and high-static-pressure fans sustain heat removal without thermal throttling. The PWM pump ramps automatically to maintain flow rate while the doubly decoupled mounting keeps vibration-induced noise low even at higher speeds. Fan speed remains stable thanks to the closed-loop motor function, preventing rpm drops that would reduce cooling capacity over time. The accessible refill port allows coolant top-ups to preserve long-term performance during continuous operation.
