Vandkøleblok Alphacool 12565

The Alphacool 12565 water block is a compact cooling component engineered for dedicated liquid-cooled PC systems. Constructed from acetal, aluminum and brass, and finished in black, this water block measures 65 mm in width and depth with a height of 30 mm, providing a balance of thermal contact area and minimal spatial footprint. It is tailored to transfer heat from CPU integrated heat spreaders into a liquid loop for continuous heat removal.

Advantages

The combination of acetal, aluminum and brass offers corrosion-resistant flow channels together with durable mounting surfaces and effective heat conduction. Its compact dimensions make it suitable for tight layouts and small form-factor builds, while the black finish integrates visually with most system interiors. Designed to support a wide range of CPU sockets, the block simplifies compatibility for multi-platform builds.

Suitable for

• Custom closed-loop or open-loop PC liquid cooling systems
• Small form-factor and mid-tower desktop builds where space is limited
• System upgrades aimed at reducing CPU temperatures under sustained load
• Multi-platform test benches requiring broad socket compatibility

Key specifications

• Dimensions: 65 mm (width) × 65 mm (depth) × 30 mm (height)
• Materials: acetal housing, aluminum components, brass internal parts
• Weight: 0.461 kg
• Finish: black
• Supported processor sockets: wide range of desktop and server sockets (including multiple LGA and AM/FM generations)

How to use

Mount the water block onto the CPU following the motherboard and cooler mounting hardware procedures. Ensure the contact surface is clean and apply an appropriate thermal interface material between the CPU heat spreader and the block. Connect the inlet and outlet fittings to compatible tubing and secure clamps or fittings to prevent leaks. Verify correct flow direction and system leak-test the loop before powering the PC components.

Recommendations

Use coolant compatible with mixed-metal loops or include corrosion inhibitors when combining aluminum and brass components. Periodically inspect fittings and tubing for signs of wear or leakage, and perform routine coolant changes according to the coolant manufacturer's guidance to maintain thermal performance.
