Water block Aqua-Computer cuplex kryos NEXT RGBpx TR4/sTRX4 — Acetal + Nickel (MPN 21809)

The Aqua-Computer cuplex kryos NEXT RGBpx TR4/sTRX4 — Acetal + Nickel is a CPU water block engineered for AMD TR4 and sTRX4 sockets. Designed for large-surface Threadripper processors, this water block combines an acetal top with a nickel-plated cold plate to deliver effective heat transfer in custom liquid-cooling loops. Integrated RGBpx lighting enables synchronized illumination with compatible controllers, while the geometry and enlarged cold plate area are optimized for high thermal loads encountered in workstations and high-end desktops.

Advantages

The combination of a nickel-plated copper cold plate and an acetal top provides a balance of corrosion resistance and efficient thermal conduction. The block’s enlarged contact area and optimized coolant channels improve heat dissipation from large-die CPUs. RGBpx lighting integration offers flexible illumination options without affecting cooling performance. The component is built for compatibility with TR4 and sTRX4 socket layouts and for straightforward installation in custom water-cooling loops.

Suitable for

• High-performance AMD Threadripper workstations and desktop systems
• Custom water-cooling loops focused on CPU cooling of large-die processors
• Systems requiring synchronized RGB lighting with compatible controllers
• Environments with sustained high CPU workloads such as rendering, simulation, and content creation

Key specifications

• Socket compatibility: AMD TR4 / sTRX4
• Top material: acetal
• Cold plate material and finish: nickel-plated copper
• Lighting: RGBpx-compatible integrated LEDs
• Cooling concept: full-coverage cold plate for large-die CPUs
• Mounting: multi-bolt mounting pattern matching TR4/sTRX4 layouts

How to use

Install the water block onto the CPU according to the motherboard and cooler manufacturer’s mounting instructions for TR4/sTRX4 sockets. Ensure the cold plate surface and CPU heatspreader are clean before applying a thin, even layer of thermal interface material. Connect the water block to the custom loop using appropriate fittings and tubing rated for your coolant. Attach the RGBpx LED connector to a compatible controller or header if lighting control is desired, and bleed the loop to remove air before powering the system.

Recommendations

For optimal cooling performance and longevity, use high-quality coolant and compatible corrosion inhibitors, verify suitability of fittings and tubing diameters for the block’s inlet/outlet ports, and follow periodic maintenance to flush and replace coolant according to the coolant manufacturer’s guidance.
