Cooler Master MasterLiquid 240L Core ARGB 240mm AIO

The Cooler Master MasterLiquid 240L Core ARGB is a 240mm all-in-one liquid cooler built around a Gen S dual-chamber pump and an expanded aluminium radiator. Two 120mm ARGB PWM fans with rifle bearings provide adjustable airflow up to 71.93 CFM. Pre-applied CryoFuze thermal paste rated at 14W/Mk is included for quick installation. The pump operates below 12dBA while the fans reach 27.2 dBA at full speed.

Builders seeking broad socket support

This cooler suits builders who want a compact 240mm radiator with addressable RGB lighting and wide mounting compatibility across many AMD and Intel platforms. It is not for buyers who need a larger radiator surface or higher static pressure for extreme overclocking. It is also not for systems that cannot accommodate a 277mm radiator length or 25mm thick fans in a dual-fan layout.

Gen S dual-chamber pump

The Gen S dual-chamber pump uses a redesigned copper base to target CPU heat spots with increased water flow and pressure. Combined with the expanded radiator fin surface, this design accelerates heat dissipation from the coolant. This pump-and-radiator combination is the specification that determines whether the cooler matches your thermal requirements.

Questions about this item

How can I verify the Gen S dual-chamber pump is running after installation?

The pump operates below 12 dBA, so listen for a faint hum at the 81 x 76 x 47 mm block and confirm coolant temperature drops in BIOS or monitoring software once the CPU loads.

What comes in the box and what must I supply myself?

The package includes the 240 mm radiator, two 120 mm ARGB PWM fans, Gen S pump block with pre-applied CryoFuze paste, and mounting hardware for AMD AM5/AM4 and Intel LGA 1851/1700/1200; you only need a motherboard ARGB header or controller for lighting sync.

Which version should I choose if my CPU socket is Intel LGA 1700?

This single model MLW-D24M-A18PZ-R1 supports Intel LGA 1700 out of the box, so no alternative version is required for that platform.
