The Cooler Master MasterLiquid 240 Atmos ARGB is a closed-loop liquid cooler built for enthusiasts, moving heat away from the CPU so it holds performance through long gaming sessions and heavy workloads. SickleFlow Edge PWM fans keep noise down while maintaining cooling efficiency, and the customisable pump top and ARGB lighting let you set how the loop looks. It supports AMD Ryzen AM5 and AM4 processors and uses CryoFuze thermal compound.

The MasterLiquid 240 Atmos is Cooler Master's next generation of AIO liquid cooling, with whisper-quiet operation from the SickleFlow Edge fans. The experience is built end to end, from the unboxing through to the MasterCTRL software, and the pump top cover accepts your own 3D-printed designs. Eco-friendly materials run throughout, and a refined dual chamber pump handles the efficiency.

Mounting hardware covers AMD Ryzen AM5 and AM4 processors, so the cooler carries across a platform upgrade instead of being replaced with the motherboard. CryoFuze thermal compound handles the transfer from the CPU into the cold plate, which is where an AIO either delivers its rated performance or quietly gives some of it away.

The latest patented dual chamber design separates intake from output to improve cooling synergy, raising water pressure and driving flow directly at the CPU hot spot for more efficient heat dissipation. The pump itself is produced with automated accuracy and a full production history is retained for quality control on every unit built.

The pump top cover is made from recycled plastics, and 35% of the cooler's metal components are recyclable. Packaging is part of the same effort, cutting total size by 30%, which reduces both material use and transport volume. It makes the MasterLiquid 240 Atmos one of the more eco-conscious options in the AIO category.

SickleFlow Edge 120mm fans come already mounted to the radiator, which removes the fiddliest part of an AIO installation and the risk of over-tightening a screw into the fins. They also carry the cooling efficiency the loop depends on, so the pre-installed set is the set you want rather than a placeholder.

MasterCTRL gives the Atmos an updated, straightforward software interface for controlling the cooler, and modern packaging carries that thinking through to first setup. Personalisation goes further than lighting: the pump top cover accepts your own 3D designs, and full control of the ARGB Gen 2 lighting sets the visual character of the loop.

Tube clips are supplied in the box to hold the tubing in a set position rather than letting it fall where it wants. They keep the installation looking streamlined behind the glass and add support that improves the cooler's overall stability, which matters most in a case where the tubes have to bend around other components.
