Water block EK Water Blocks Nickel Black 27mm

The EK Water Blocks 3831109897270 Nickel Black 27mm is a high-performance GPU water block engineered for efficient cooling of modern graphics cards. Constructed with a nickel-plated copper cold plate and a robust enclosure, this model targets the GPU core, voltage regulation module (VRM) and GDDR6X memory areas to maintain lower operating temperatures under heavy load. The product follows the EK-Matrix7 standardized dimensions for easier loop planning and integrates addressable D-RGB lighting mounted along the longest edge for consistent illumination.

Advantages

This water block uses an 11 mm thick copper cold plate and a 3D-machined acrylic jet insert with an Open Split-Flow design that evens flow distribution across the fin array, delivering effective heat transfer while keeping hydraulic flow restriction low. The design supports reversed flow scenarios and works with lower-speed pumps. A captive-screw backplate provides passive cooling for PCB hotspots and simplifies installation, while rotatable magnetic covers conceal terminal screws and allow correct branding orientation in different mounting positions.

Suitable for

• Custom liquid-cooled gaming and workstation PCs with supported Zotac RTX 4080 cards (AMP Extreme AIRO and Trinity)
• Systems requiring efficient GPU, VRM and VRAM cooling under sustained load
• Builds using EK-Matrix7 components and EK-Quantum Reflection² distribution plates

Key specifications

• Material: nickel-plated copper cold plate, aluminum extrusion for LED housing
• Cold plate thickness: 11 mm
• Compatibility: designed for specific Zotac RTX 4080 variants; follows EK-Matrix7 standard
• Lighting: addressable D-RGB (3-pin, +5V | Data | Blocked | Ground)
• Included: captive-screw backplate and rotatable magnetic covers
• Dimensions (from product data): width 27 mm, depth 272.5 mm, height 155 mm

How to use

Mount the water block onto the compatible graphics card following the manufacturer's mounting instructions, ensuring correct alignment with the EK-Matrix7 standard ports. Connect the 3-pin D-RGB cable to a +5V addressable RGB header on the motherboard, aligning the arrow on the connector with the +5V marking. Integrate the block into a closed-loop liquid cooling system, verifying pump flow direction and secure tubing connections. Tighten captive backplate screws to the specified torque to avoid uneven pressure.

Recommendations

Use with compatible Zotac AMP Extreme AIRO and Trinity RTX 4080 cards and EK-Matrix7 components. Operate with a pump and radiator setup appropriate for your loop; because the block has low hydraulic restriction, it can function well with moderate pump speeds. Regularly inspect sealing surfaces and replace thermal interface materials when re-installing the block.
