Backplate Alphacool 13071 acier inoxydable noir 90 mm

The Alphacool 13071 Backplate Stainless Steel Black 90mm is a compact support plate designed for use in computer cooling assemblies. Constructed from stainless steel with a black surface finish, the 90mm x 90mm plate and its 3mm thickness provide a rigid mounting surface that enhances component stability and contributes to a clean, uniform appearance in system builds. The backplate is intended to sit behind cooling elements to deliver mechanical support while maintaining a low profile inside the chassis.

Advantages

The stainless steel construction offers high rigidity and corrosion resistance, preserving structural integrity over time. The black finish provides consistent visual integration with dark-themed builds and reduces visible reflections. At 3mm thickness and a 90mm square size, the backplate combines compact dimensions with sufficient strength to support cooling hardware without occupying excessive space behind the motherboard or radiator. The simple geometry and durable material also simplify installation and long-term maintenance.

Suitable for

• Supporting small to medium-sized cooling components in custom PC water-cooling loops
• Reinforcing mounting points to reduce strain on motherboard traces and sockets
• Improving visual consistency in black or dark-colour system builds
• Environments where a slim, rigid support plate is required behind radiators or pump tops

Key specifications

• Material: stainless steel
• Finish: black surface coating
• Dimensions: 90 mm × 90 mm
• Thickness: 3 mm
• Shape: square plate

How to use

Position the backplate behind the cooling component so that mounting holes align with the corresponding fasteners. Use appropriate screws and washers compatible with your cooling hardware to secure the plate, ensuring even contact without over-tightening. The plate may be used directly behind radiator fittings, pump tops, or other cooling elements where additional rigidity is required. Verify clearance inside the chassis before final mounting to maintain proper cable routing and airflow.

Recommendations

Before installation, inspect the backplate and mounting points for burrs or sharp edges and handle with gloves if needed. Tighten fasteners incrementally in a cross pattern to distribute pressure evenly. Avoid using excessive force that could deform the plate or stress surrounding components. For optimal aesthetics and corrosion resistance, keep the black surface free from abrasive cleaners; a soft cloth and mild detergent are sufficient for cleaning.
