At the 2023 International CES, Cooler Master showed off two of its latest premium dual fin-stack (type-D) air CPU coolers, the MasterAir MA826 Stealth, and the Hyper 662 Halo. The MA826 Stealth is, unsurprisingly, the more upmarket of the two, and measures 162.2 mm x 150.6 mm x 165.6 mm (LxWxH). A nickel-plated copper base makes contact with the processor. From here eight 6 mm-thick composite-material "superconductive" heatpipes make their way to two aluminium fin-stacks, which are then ventilated by two Mobius series fans—a 120 mm "push" fan, and a 135 mm conveyor fan located between the two fin-stacks. The two stacks are capped off by a die-cast aluminium top-plate. Both fans feature loop dynamic bearings that are rated for over 200,000 hours operation.

The Hyper 662 Halo leads the company's immensely popular Hyper series that's synonymous with aftermarket CPU cooling. This cooler comes in all-white and all-black trims, and is visibly smaller than the MA826 Stealth. It features the same nickel-plated copper base, but with six heatpipes making their way to the two fin-stacks, and a pair of 120 mm fans handling the ventilation. The fans feature two ARGB LED zones (along the bore of the frame and inside the impeller hub), which is where the Holo name derives from. Both coolers support the latest CPU socket types, including LGA1700 and AM5.
