Water block Alphacool 13447 Brass Copper Silver RGB 5V

The Alphacool 13447 Brass Copper Silver RGB 5V water block is a compact cooling component designed for direct contact with modern CPUs. Constructed from brass and copper materials and finished in silver, the block measures 72mm x 72mm x 26.5mm and provides a low-profile solution for liquid cooling loops. Integrated 5V RGB illumination offers customizable lighting while the metal construction supports effective thermal transfer from the processor to the coolant.

Advantages

The combination of brass and copper ensures high thermal conductivity and structural durability, while the compact footprint allows installation in a variety of chassis and custom loops. The 5V RGB lighting adds visual integration with compatible controllers without affecting cooling performance. Compatibility with multiple mainstream processor sockets increases versatility for system builders and upgraders.

Suitable for

• Custom liquid cooling loops for desktop CPUs
• High-performance gaming PCs and workstations
• Compact builds where a low-profile water block is required
• Systems requiring synchronized 5V RGB lighting

Key specifications

• Material: brass base with copper contact surfaces
• Finish / colour: silver
• Dimensions: 72 mm x 72 mm x 26.5 mm
• Weight: 0.5 kg
• RGB interface: 5V compatible lighting
• Supported sockets: LGA 1700, Socket AM5, Socket AM4

How to use

Mount the water block directly onto the processor following the mounting hardware and torque specifications provided by your motherboard or mounting kit. Ensure the contact surface and CPU heatspreader are clean and apply an appropriate thin layer of thermal compound. Integrate the block into a closed-loop liquid cooling system with compatible fittings and tubing, and connect the 5V RGB header to a compatible controller or motherboard RGB header for lighting control. Verify secure sealing to prevent leaks and run the loop to check flow and temperatures before full system operation.

Recommendations

Use a high-quality, non-conductive coolant and compatible fittings. Periodically inspect seals and tubing for wear and perform maintenance on the loop every 6–12 months depending on usage. When installing on different sockets, use the correct mounting brackets and follow manufacturer torque guidance to maintain contact pressure and avoid damage to the CPU or block.
