At the 2023 International CES, Cooler Master showed off a unique all-in-one liquid closed-loop CPU cooler that features user-replaceable pump-block covers, the MasterLiquid Atmos. The top cover of the pump-block comes off, so you can replace it with something with a different shape or color. Examples of these covers include a frosty-white cover made of recycled plastic resin, or a tinted acrylic diffuser. Underneath is a white silicone diffuser for an ARGB lighting element. The lighting extends to the included Cooler Master Sickleflow ARGB fans.

The MasterLiquid Atmos model shown at CES was the ML360 Atmos, featuring a 360 mm x 120 mm radiator with a trio of Sickleflow ARGB fans. These fans come pre-installed on the radiator, to minimize packaging waste. The ML360 Atmos uses a dual-chamber pump-block, which features CM's Gen 2 ARGB lighting. The company didn't go into the technical details of the fan, but mentioned its top speed to be 2,400 RPM. The MasterLiquid Atmos series comes in two variants, 240 mm and 360 mm. Among the CPU socket types supported are LGA1700, LGA1200, AM5, and AM4.
