Vandblok Alphacool 13446 messing kobber sort 72 mm

The Alphacool 13446 Brass Copper Black 72mm water block is a compact processor cooling component combining brass and copper for thermal conductivity and durability. Its black finish and 72mm x 72mm x 26.5mm dimensions make it suitable for space-constrained builds while the integrated 5V RGB support provides configurable lighting for modern systems. Designed to interface directly with CPUs, the block focuses on efficient heat transfer from the processor to a liquid cooling loop.

Advantages

The construction uses brass and copper to balance mechanical strength and thermal performance, while the compact footprint reduces clearance issues in tight cases. The black exterior offers a neutral appearance that integrates with many build styles. Native compatibility with common contemporary sockets ensures straightforward integration on supported motherboards. Built-in 5V RGB allows synchronization with compatible controllers to maintain uniform system lighting.

Suitable for

• Custom liquid-cooled desktop PCs where space is limited
• Workstations and gaming systems requiring improved CPU thermal management
• Builds that include 5V RGB lighting for coordinated aesthetics

Key specifications

How to use

Mount the water block onto the processor following standard liquid-cooling installation procedures and the mounting hardware supplied by your cooling system. Ensure the CPU surface and the block contact area are clean and apply an appropriate, thin layer of thermal interface material before securing the block. Connect the block to the loop with compatible fittings and tubing, verify leak-free connections, and connect the 5V RGB header to a compatible controller if lighting is required. Power on the loop pump and monitor temperatures to confirm correct operation.

Recommendations

Inspect mounting hardware compatibility with the target motherboard and use recommended coolant and corrosion inhibitors for mixed-metal loops. Follow safe liquid-cooling practices: perform a leak test before powering other components, routinely check fittings and coolant condition, and ensure the pump provides sufficient flow for the linked radiator and block configuration.
