Water block Aqua-Computer cuplex kryos NEXT sTRX4 Full Cover Acryl — compatible with sTRX4 sockets

Aqua-Computer cuplex kryos NEXT sTRX4 Full Cover Acryl is a full-cover CPU water block engineered for AMD sTRX4 sockets. The block features an acrylic top and a precision-machined copper cold plate that directs coolant over the CPU and adjacent VRM area, enabling efficient heat extraction in custom liquid-cooling loops. Designed for high-performance workstations and overclocked systems, this full-cover solution integrates into multi-component cooling circuits to maintain lower operating temperatures under sustained heavy loads.

Advantages

The full-cover design cools both the processor die and surrounding components, improving overall thermal management compared with CPU-only blocks. The acrylic top provides visual access to coolant flow and simplifies leak inspection, while the copper cold plate and internal micro-channel geometry promote rapid heat transfer. The block is compatible with standard fittings used in custom loops and is constructed to provide a reliable seal and stable mounting on sTRX4 platforms.

Suitable for

• High-performance workstation systems using sTRX4 CPUs
• Custom liquid-cooling loops in overclocked or sustained-load environments
• System builds where cooling of VRM and surrounding components is required
• Enthusiast rigs aiming for lower CPU and motherboard temperatures

Key specifications

• Compatibility: AMD sTRX4 socket full-cover water block
• Top material: acrylic
• Cold plate material: copper (precision machined)
• Interface: direct liquid cooling for CPU and surrounding components
• Fitting connections: standard G1/4"-compatible threads (fits common custom-loop fittings)
• Mounting: full-cover mounting for sTRX4 form factor

How to use

Install the water block following the motherboard and case manufacturer guidance for sTRX4 sockets, ensuring the contact surface on the CPU and cold plate is clean and flat. Apply a thin, even layer of thermal interface material on the CPU heat spreader where recommended, align the block and secure it with the supplied mounting hardware to the socket. Connect inlet and outlet fittings to the block using suitable tubing and leak-test the loop at low pressure before regular operation. Monitor coolant flow and temperatures during initial runs to verify proper installation.

Recommendations

Use corrosion-inhibiting coolant compatible with copper and acrylic components, maintain the loop by periodic coolant replacement and cleaning, and perform a leak test after each disassembly. For best thermal performance, ensure adequate pump flow and use radiators sized appropriately for the system’s heat load.
