Water block Alphacool 15380 Acrylic Aluminium Plastic Black 76.5x131x76.5mm

The Alphacool 15380 water block is a compact cooling component designed for directed heat transfer in liquid-cooled computer systems. Constructed from acrylic, aluminium and plastic with a black finish, this block measures 76.5 x 131 x 76.5 mm and is intended to integrate into custom loops where space efficiency and effective thermal contact are required. The visible acrylic top allows for inspection of coolant flow while the aluminium base provides a conductive interface for heat dissipation.

Advantages

The combination of acrylic and aluminium balances visual inspection and thermal conductivity, providing stable contact with cooling liquid and reliable heat transfer. The black finish reduces visible reflections and matches common system aesthetics. Its compact footprint supports installation in tighter layouts without sacrificing the core functionality of a dedicated water block designed for component cooling.

Suitable for

• Custom PC liquid-cooling loops where a compact water block is required
• Cooling individual components such as pumps, small radiators, or breakout points in a loop
• Systems with limited internal space that still require effective heat transfer

Key specifications

• Materials: acrylic top, aluminium contact surfaces, plastic fittings
• Color: black finish
• Dimensions (W x D x H): 76.5 x 131 x 76.5 mm
• Top: transparent acrylic for visual coolant monitoring
• Base: aluminium for conductive heat transfer
• Connector compatibility: standard liquid-cooling fittings (verify size before installation)

How to use

Mount the water block into the liquid-cooling loop following the system layout, ensuring flat and secure contact between the aluminium base and the component or surface to be cooled. Use appropriate thermal interface material where required and tighten fittings to the manufacturer's recommended torque to prevent leaks. Verify that tubing and connectors are compatible, then fill, bleed and inspect the loop for proper flow and absence of leaks before powering the system.

Recommendations

Before installation, confirm compatibility with your loop fittings and available space. Use recommended coolant types and avoid abrasive or conductive additives that could damage the acrylic or aluminium surfaces. Periodically inspect seals and the acrylic top for signs of wear or deposits, and perform routine maintenance on the cooling loop to maintain optimal performance.
