Our 4.5-star review praised the Atmos 240 for delivering performance that often matches bulkier 360mm coolers, all while maintaining low noise levels. The package includes two Sickleflow Edge 120mm fans, CryoFuze thermal paste with applicators, a PWM splitter, and an ARGB hub and splitter. It supports all modern CPU sockets, and its low-profile CPU block ensures compatibility with tall RAM heat spreaders. With a total radiator and fan thickness of just 52mm, it fits easily into small-form-factor cases.

Inside the box, you’ll find mounting hardware for current platforms, along with a premium dual-chamber pump and CPU block featuring subtle RGB lighting and an ARGB Gen 2 hub. During testing, the cooler handled even the most demanding processors effortlessly, and for less power-hungry chips, it operates with plenty of headroom.

When paired with a Core i7-13700K, the Cooler Master AIO reached only 38.2 dBA under default fan curves, staying quiet during typical use. Noise levels can increase under extreme loads, but given its cooling capability, the Atmos 240 remains a compelling option, whether you have a spacious chassis or a compact build limited to 240mm radiators.

The current discount makes this one of the best-value cooling deals available. Its understated design avoids the overly flashy look common in many RGB components, while the low-profile construction ensures broad compatibility.
