Sudokoo brought a fascinating new lineup of CPU coolers, AIO CLCs, and fans to the 2026 International CES. We begin our coverage with fans, and the new Sudokoo Astra, a 120 mm fan designed for radiators, with a quick-connect magnetic daisy-chaining mechanism that lets you shed cables for the 2nd and 3rd fans. This 7-pin connector shares both 4-pin PWM and 3-pin ARGB connections to the neighboring fans. The fan features a 3-phase, 6-slot, 4-pole DC motor, with a fluid dynamic bearing, and a liquid crystal polymer impeller. It will come in white and black color variants based on frame color, and various variants based on impeller pattern.

Moving on to all-in-one liquid CPU coolers, and we have the AetherFlex 360, a flagship cooler with a large 4.5-inch true-color display with 854 x 480 pixels resolution, which can be made to display just about anything, but by default puts out useful system monitoring stats pulled from ACPI. It features a high flowrate 3400 RPM pump, and a magnetic mounting mechanism lets you orient the screen either portrait, or landscape, or pulled out altogether. The Energlo AIO CLC features a cube-shaped pump-block with a unique fan design that illuminates the inside of the impeller hub—hence the name. The Proteus comes in sizes as large as 420 mm x 140 mm, and features a 3.4-inch LCD with 480 x 480 pixels resolution. The AetherFlex can handle 320 W thermal loads, Energlo 360 can do 310 W, while the Proteus 420 can do 350 W.

At CES 2026, SUDOKOO, an engineering-driven PC cooling brand, will make its first official global debut, unveiling a new lineup of high-performance CPU air coolers and liquid cooling solutions designed for workstations, PC enthusiasts, creators, and professional users. The showcased products span workstation-class air cooling, low-profile vapor-chamber air coolers, enthusiast-grade tower coolers, and LCD-equipped liquid CPU coolers, reflecting SUDOKOO's engineering-first approach to modern thermal design.
