## Summary description

Aqua-Computer cuplex kryos NEXT RGBpx TR4/sTRX4 is a CPU water block designed for AMD TR4 and sTRX4 sockets. It features an acrylic top and nickel-plated coldplate for efficient heat transfer, integrated RGBpx lighting support, and mounting for large-surface CPUs. Intended for custom liquid cooling loops to improve thermal performance in high-core-count Ryzen Threadripper systems.

## Long description

The Aqua-Computer cuplex kryos NEXT RGBpx TR4/sTRX4 — Acryl top, Nickel base is a dedicated CPU water block engineered for AMD TR4 and sTRX4 socket processors. Designed for custom liquid cooling loops, it combines an acrylic top with a nickel-plated coldplate to provide effective heat conduction and a visible coolant channel. The block includes integrated RGBpx-compatible lighting for addressable illumination and a mounting concept adapted to large-surface CPUs used in high-core-count Threadripper systems.
Advantages
The acrylic top offers a clear view of coolant flow and lighting effects while the nickel-plated base ensures corrosion protection and reliable thermal transfer. The design accommodates the larger heatspreader area of TR4/sTRX4 CPUs, providing uniform contact and optimized coolant distribution. Built for custom loops, the block supports high flow rates and is compatible with standard G1/4 fittings, enabling straightforward integration into existing liquid cooling systems.
Suitable for
Cooling high-core-count AMD Ryzen Threadripper processors on TR4 or sTRX4 sockets
Custom liquid cooling loops in workstations and high-performance desktops
Systems where visible coolant flow and addressable RGB lighting are desired
Overclocking setups requiring improved thermal dissipation and stable temperatures
Key specifications
Socket compatibility: AMD TR4 and sTRX4
Top material: Acrylic (transparent)
Coldplate material: Nickel-plated metal for corrosion resistance and heat transfer
Lighting: Integrated addressable RGBpx lighting support
Fitting compatibility: Standard G1/4 fittings
Design focus: Large-surface CPU contact and optimized coolant channels
How to use
Mount the water block onto a correctly prepared TR4 or sTRX4 CPU following the motherboard and cooler manufacturer torque specifications. Ensure the coldplate and CPU heatspreader surfaces are clean and apply an appropriate thermal interface material before securing the block. Connect inlet and outlet fittings to your loop tubing and verify correct flow direction. Integrate the RGBpx lighting cable into an addressable lighting hub or compatible controller and test both cooling and lighting functions before full system operation.
Usage recommendations
Use non-conductive, corrosion-inhibited coolant and maintain regular loop maintenance, including periodic coolant replacement and visual inspection of joints and drain points. Check that fittings are tightened to specification and monitor temperatures after initial installation and during heavy workloads to confirm expected thermal performance.
