## Long description

EK Water Blocks 3831109844304 Acetal Nickel Black Grey 285mm is a precision GPU water block engineered for direct liquid cooling of high-performance graphics cards. Constructed from acetal and nickel-plated components and finished in black and grey, the block measures 285 mm wide, 16.5 mm deep and 149 mm high. It is designed to remove heat from the GPU die, surrounding VRAM and VRM power stages by channeling coolant over these critical areas, improving thermal performance and supporting sustained workloads.
Advantages
The water block uses an Open Split-Flow cooling engine with an optimized jet plate and fin geometry to provide even coolant distribution and reduced hydraulic resistance. This design minimizes vortexing and dead spots while allowing efficient operation with a wide range of pump strengths. Nickel plating improves corrosion resistance and heat transfer at contact surfaces while the acetal top provides structural stability and a clean visual appearance in black and grey tones.
Suitable for
Custom liquid-cooled gaming systems that require direct GPU cooling
High-load workstation GPUs used for rendering or simulation
Silent or low-RPM pump loops where low hydraulic restriction is advantageous
Enthusiast builds seeking a compact, high-performance GPU cooling solution
Key specifications
Type: GPU water block designed for direct cooling of GPU, VRAM and VRM
Materials: acetal top with nickel-plated cold plate and contact surfaces
Colour: black and grey finish
Overall dimensions: 285 mm (width) × 16.5 mm (depth) × 149 mm (height)
Cooling engine: Open Split-Flow with optimized jet plate and fin structure
Hydraulic characteristics: low flow restriction suitable for low-speed pumps
How to use
Install the water block onto the compatible graphics card following the manufacturer’s mounting instructions and use the recommended thermal interface material on the GPU die and other contact points. Connect the block into your closed-loop or custom loop using appropriate fittings and tubing, ensuring leak-tested connections and correct coolant flow direction. Prime and run the loop while monitoring temperatures to confirm correct installation and flow. For compatibility details and model matching refer to the EK compatibility resources.
Usage recommendations
Use corrosion-inhibited, manufacturer-recommended coolant and perform regular maintenance such as coolant replacement and leak checks. Pair the water block with an appropriate backplate or retention plate when available to improve mechanical support and passive cooling of the PCB. Ensure the 3-pin D-RGB connector (if present on compatible variants) is aligned correctly with the +5V header for RGB synchronization.
