Liquid CPU cooler Cooler Master MasterLiquid 240 Core II White — 240 mm, 2x 120 mm fans (650–1750 RPM), sleeve bearing

Cooler Master MasterLiquid Core II Series is a redesigned liquid CPU cooler that combines a compact dual-chamber G9R pump with an infinity mirror pump cover and optimized tubing for flexible installation. The cooler includes revamped 120 mm fans with daisy-chain connection, supports current Intel and AMD sockets including LGA 1851 RL-ILM, and ships with Cryo-Fuze thermal paste for straightforward assembly.

Advantages

The Core II Series offers a quiet dual-chamber pump for stable cooling performance and a refined aesthetic thanks to the infinity mirror pump cover. Longer 400 mm tubing allows easier placement and mounting in various orientations, while the updated fan design and daisy-chain connection simplify cable management and improve airflow efficiency. Compatibility with the latest Intel and AMD sockets provides broad build flexibility.

How to use

Mount the radiator and fan(s) in the desired location inside the case, route the 400 mm tubes to the CPU area, and secure the pump unit over the CPU using the appropriate socket bracket for your processor. Connect the fans using the daisy-chain wiring to the motherboard or fan hub and attach the pump power connector. Apply the included Cryo-Fuze thermal paste to the CPU before seating the pump cold plate, then tighten mounting screws evenly to ensure proper contact.

Recommendations

Ensure your case has sufficient clearance for a 120 mm radiator and verify support for the RL-ILM LGA 1851 socket if using that platform. Clean old thermal material thoroughly before applying Cryo-Fuze and follow motherboard instructions for pump and fan connectors to enable PWM control.
