Product information

Description

The Alphacool 13426 Acrylic Aluminium Chrome Copper Black Transparent water block with matching backplate is a combined cooling component designed to lower GPU temperatures while adding visual refinement to a PC build. Constructed from acrylic and aluminium with copper contact surfaces and chrome accents, the unit integrates an RGB lighting element that runs at 5 V. Its compact footprint — 157 mm width, 220.9 mm depth and 34.2 mm height — is suitable for many modern graphics card layouts and custom loop configurations.

Advantages

This water block and backplate pair provides effective thermal transfer through copper contact areas and a broad coolant channel visible through the transparent acrylic top. The aluminium backplate helps reinforce the graphics card and assists with passive heat dispersion across its surface. Built-in 5 V RGB lighting offers synchronized illumination with compatible controllers. The combination of durable materials and precise dimensions supports a secure fit and stable long-term operation within compatible systems.

Suitable for

  • Custom liquid-cooling loops for gaming and workstation GPUs
  • PC builds where visual transparency and chrome detailing are desired
  • Systems requiring reinforced backplate support and improved heat dissipation

Key specifications

  • Materials: acrylic top, aluminium backplate, copper contact surfaces, chrome accents
  • Dimensions: 157 mm (W) x 220.9 mm (D) x 34.2 mm (H)
  • Lighting: integrated 5 V RGB illumination compatible with standard 5 V controllers
  • Finish: black and transparent aesthetic with chrome highlights

How to use

Mount the water block onto the GPU according to the manufacturer's mounting procedure, ensuring even pressure on the contact surfaces and correct thermal interface material application. Connect the inlet and outlet to the custom loop tubing and verify secure, leak-free fittings before filling the loop. Attach the 5 V RGB connector to a compatible header or controller and configure lighting as needed. After installation, perform a leak test and monitor temperatures under idle and load to confirm correct operation.

Usage recommendations

Use a high-quality thermal paste and properly sized fittings for your tubing to ensure optimal cooling performance. Periodically inspect all connections and coolant condition; replace coolant according to your maintenance schedule to prevent corrosion and maintain flow. Ensure compatibility with your GPU model and case clearance prior to installation.
