Waterblock EK Water Blocks χαλκός POM ανοξείδωτο ατσάλι

The EK Water Blocks 3831109904695 Copper POM Stainless steel is a full-cover, high-performance water block designed to provide efficient cooling for graphics cards. Constructed from copper with POM and stainless steel elements, the block covers critical components across the length of the card to lower operating temperatures, support stable performance and extend component lifetime. Its overall dimensions are 22.3 mm (width) × 281.8 mm (depth) × 125.2 mm (height), and it is engineered to cool the GPU, VRAM and VRM directly by routing coolant over these hot spots.

Advantages

The water block uses a precision-machined copper base paired with stainless steel topside elements to combine excellent thermal conductivity with durable mechanical protection. An Open Split-Flow cooling engine minimizes hydraulic restriction, enabling effective operation with lower-flow pumps and multi-GPU systems. Factory-installed brass standoffs, EPDM O-rings for reliable sealing and an integrated I/O plate add mechanical stability and simplify installation while maintaining full NVLink compatibility.

Suitable for (tasks / use cases)

• Liquid cooling high-performance graphics cards in workstations and servers
• Multi-GPU workstations where low coolant flow and compact slot usage are required
• Systems that require single-slot external footprint while cooling GPU, VRAM and VRM
• Custom loop builds focused on lowered operating temperatures and component longevity

How to use

Prepare the graphics card by removing the factory cooler according to the card manufacturer’s instructions and clean the GPU and surrounding components of old thermal material. Position the water block so that the copper base makes contact with the GPU die, and align standoffs with the card’s mounting points. Secure the block using the supplied screws, nuts and washers, ensuring even pressure across the mounting points. Connect inlet and outlet fittings to your custom loop, fill and leak-test the loop, and verify pump and flow operation before powering the system for normal use.

Recommendations

Use compatible coolant and fittings, ensure the loop is free of conductive contaminants, and perform an extended leak test after installation. Maintain appropriate pump flow to match the block’s low hydraulic requirement, and periodically check mounting torque and coolant condition to preserve thermal performance and reliability.
