## Long description

The Alphacool 13456 Acrylic Aluminium Water Block with Backplate combines an acrylic top with aluminium structural elements in a black, silver and transparent finish. Designed for liquid-cooling configurations, it occupies a compact footprint of 205.4 mm × 147 mm × 34.6 mm and integrates a 5 V RGB voltage input for lighting control. The unit provides a consolidated cooling surface and a rigid backplate to assist heat transfer and mechanical support within compatible PC builds.
Advantages
This water block and backplate set offers a balance of visual clarity and thermal conduction thanks to the acrylic viewing area coupled with aluminum contact surfaces. Its compact dimensions allow installation in systems with limited space while still providing a broad contact area for coolant flow. The 5 V RGB input lets users integrate lighting with common motherboard headers or controllers. The integrated backplate helps distribute mechanical load and can improve heat dissipation from the rear side of the card.
Suitable for
Custom liquid-cooled gaming PCs requiring a compact full-cover GPU water block solution
Silent workstation builds where liquid cooling and a low-profile component footprint are priorities
Systems with 5 V RGB headers for synchronized lighting effects

How to use
Install the water block and backplate following the manufacturer’s mounting instructions for your specific graphics card or component. Ensure the mating surfaces are clean and that appropriate thermal interface material is applied where required. Connect the coolant tubing to the inlet and outlet ports using compatible fittings and verify leak-tight connections before filling the loop. Attach the RGB cable to a compatible 5 V header or controller and configure lighting through the system software or external controller. After assembly, perform a pressure/leak test with the loop powered off, then run the pump and monitor temperatures to confirm correct operation.
Usage recommendations
Use corrosion-inhibiting coolant and follow regular maintenance intervals to preserve thermal performance and prevent buildup. Verify compatibility with your specific card model and available case space prior to purchase; check mounting orientation and clearance for adjacent components. When routing RGB and coolant lines, avoid sharp bends and secure fittings to reduce stress on connectors.
