Alphacool 13083 Water block Brass Copper Chrome 70mm

The Alphacool 13083 Brass Copper Chrome 70mm water block is a compact cooling component engineered for liquid-cooled computer systems. Constructed from brass and copper with a chrome finish, it measures 70mm x 70mm x 32.5mm and integrates a 5V RGB lighting interface. The design focuses on direct heat transfer from processor surfaces to the cooling loop, making it suitable for a variety of mainstream and high-performance motherboard sockets.

Advantages

The combination of brass and copper ensures effective thermal conductivity and long-term durability while the chrome finish provides corrosion resistance and a uniform appearance. The compact 70mm footprint allows installation in constrained spaces or on smaller motherboards without compromising contact area. Integrated 5V RGB lighting offers visual customization compatible with common 5V RGB controllers. Broad socket compatibility reduces the need for multiple water block variants across different builds.

Suitable for

• Custom liquid cooling loops in desktop PCs
• Cooling mainstream and high-performance CPUs across supported sockets
• Compact or small-form-factor builds requiring a 70mm cooling solution
• Systems where visual coordination with 5V RGB lighting is desired

How to use

Mount the water block onto the target processor following standard liquid-cooling installation procedures: prepare the mounting bracket and thermal interface material, align the block to the processor socket, and secure it evenly to ensure consistent contact pressure. Connect the block to the cooling loop with appropriate fittings and tubing rated for PC liquid cooling systems. Attach the 5V RGB connector to a compatible controller or motherboard header to enable lighting. Verify for leaks before normal operation and run the pump at recommended speeds for steady coolant flow.

Recommendations

Use a high-quality thermal paste and torque mounting screws gradually and evenly to avoid uneven pressure. Ensure fittings and tubing are compatible with the block’s inlet/outlet size and check all connections for leaks during an initial filled run. Maintain the loop by periodically inspecting coolant condition and replacing coolant per the cooling system manufacturer’s guidance.
