Backplate Alphacool 13554 — copper backplate for computer cooling, 215.5×145.9×34.2 mm, black/silver/transparent

Alphacool 13554 is a copper backplate designed for computer cooling systems, measuring 215.5 × 145.9 × 34.2 mm. Supplied in black, silver or transparent finish, the single-piece backplate provides structural reinforcement for the graphics card area and improves thermal contact in custom liquid-cooling loops and high-performance PC builds. The copper construction supports heat dissipation from components on the PCB and integrates visually with water-block assemblies that use metal contact surfaces.

Advantages

The solid copper construction offers high thermal conductivity to aid heat transfer away from PCB-mounted components. As a one-piece backplate it increases mechanical rigidity and helps reduce PCB flex under heavy cooler and connector loads. Available in three finishes — black, silver or transparent — it can match different build aesthetics while maintaining the thermal and structural properties of copper. The dimensions provide full coverage for compatible water cooler assemblies and make installation straightforward when paired with matching mounting points.

Suitable for

• Custom liquid-cooling loops where a copper backplate is required for thermal contact and support
• High-performance GPU builds that require additional PCB reinforcement and heat spread
• System builds aiming for coordinated aesthetics with black, silver or transparent metal finishes

Key specifications

• Material: copper
• Overall dimensions: 215.5 × 145.9 × 34.2 mm
• Finish options: black, silver, transparent
• Design: single-piece backplate for structural support and thermal contact

How to use

Install the backplate following the water-cooler or GPU block manufacturer’s mounting instructions. Ensure the PCB is supported and that thermal pads or paste recommended for your cooling assembly are placed between the backplate and contact points on the board where required. Tighten mounting hardware evenly in a cross pattern to avoid uneven pressure on the PCB. Verify clearance inside the case for the stated dimensions and confirm alignment with screw holes and standoffs before final tightening.

Usage recommendations

Use compatible thermal pads or interface materials where the backplate will contact voltage regulators and memory modules; follow the thermal pad thickness and thermal conductivity guidance from your water block or component manufacturer. Check that the selected finish matches your cooling loop materials and avoid exposure to dissimilar metals without appropriate coolant additives to prevent galvanic corrosion.
