Cooler Master at the 2025 International CES showed us the latest update to its AIO, closed-loop liquid CPU cooler series, the MasterLiquid Atmos II. This is a generational update to the original ML Atmos from 2023. It comes with a thinner pump-block that you can stack a variety of attachments on. As part of the Flex Kit for Atmos II, there are a number of attachments such as simply metal plates in chrome or gunmetal finishes, a Cooler Master illuminated hexagon with infinity mirror, a coarse LED segment display that can be programmed to put out system monitoring info, a true-color display, as well as a mini 30 mm fan inside a mesh. You can swap attachments out on the fly. The MasterLiquid Atmos II will come in 280 mm and 360 mm radiator sizes.

Next up, Cooler Master showed off its latest MasterFan products, which include the MasterFan XT ARGB, MasterFan XT, and MasterFan XT Pro. The XT Pro is a standout product, offering speeds as high as 3,000 RPM, with 10-15 mm H₂O static pressure, and 101 to 125 CFM of airflow, with noise outputs ranging between 40 and 44 dBA. These come with a dual-ball bearing that's rated for over 200,000 hours, and Cooler Master is backing these with a 6-year product warranty.
