Water block Alphacool 12993 Acetal Copper Nickel Black 52mm 56mm 22.5mm

The Alphacool 12993 Acetal Copper Nickel Black water block is a compact cooling component designed for targeted heat dissipation in desktop computer systems. Constructed from acetal for the top housing with a copper cold plate and nickel plating for corrosion resistance, this unit balances durability and thermal performance. Its external dimensions are approximately 52mm (width) x 56mm (depth) x 22.5mm (height), offering a small footprint suitable for constrained mounting locations while delivering direct-liquid cooling to reduce component temperatures and extend hardware life.

Advantages

This water block combines a copper cold plate for efficient thermal conduction with nickel plating to reduce oxidation and improve long-term stability. The acetal top provides robust mechanical strength and a clean visual appearance in black finish. Its compact dimensions make it adaptable to tight installation spaces without compromising on coolant flow paths and contact surface quality, enabling efficient heat transfer from localized hot spots.

Suitable for

• Cooling CPUs or small form-factor GPUs where compatible mounting and contact area are available
• Custom liquid cooling loops in compact or densely packed PC cases
• Overclocked systems requiring improved thermal management for sustained performance
• Repairs or upgrades where a compact, metal-cold-plate water block is needed

Key specifications

• Material (top): acetal
• Cold plate material: copper with nickel plating
• Finish: black
• Approximate dimensions: 52 mm (width) × 56 mm (depth) × 22.5 mm (height)
• Design: single-block cold plate with ports for liquid coolant connection

How to use

Mount the water block onto the target component ensuring the cold plate makes full contact with the heat source using an appropriate thermal interface material. Secure the block with the compatible mounting hardware for your platform and connect inlet and outlet tubing to the cooling loop using appropriate fittings and clamps. Verify that the loop is filled, bled of air, and that flow is established before applying full system load. Periodically inspect fittings and coolant condition to maintain reliable operation.

Recommendations

Use a high-quality thermal paste between the cold plate and the component surface, compatible tubing and fittings rated for your coolant, and a corrosion-inhibiting coolant compatible with nickel-plated copper. Follow the system builder’s torque and mounting guidelines to avoid uneven pressure on the cold plate. For best results, integrate the water block into a well-planned loop with adequate radiator capacity and pump flow.
