Water block Alphacool 13327 Acetal Aluminium Black Transparent 5V RGB

The Alphacool 13327 Acetal Aluminium Black Transparent 5V RGB water block is a compact cooling component designed for liquid-cooled computer systems. Constructed from acetal and aluminum, the block combines corrosion-resistant acetal material for the top housing with a solid aluminum base to provide reliable heat transfer. The transparent section allows visual inspection of coolant flow while integrated 5V RGB support enables synchronized lighting with compatible controllers and motherboard headers. The unit measures 65 mm x 65 mm x 41 mm and is built to fit within small to mid-size loop configurations.

Advantages

The water block's acetal top offers chemical resistance and a clear view of coolant movement, while the aluminum contact surface improves thermal conductivity to the cooling loop. Compact dimensions reduce space requirements inside the chassis. Support for 5V RGB lighting adds visual customization without affecting core cooling performance. The combination of materials provides a balance between durability, weight, and effective heat dissipation.

Suitable for

• Custom liquid cooling loops in desktop PCs
• Small form factor builds where space is limited
• Systems requiring visual monitoring of coolant and RGB lighting
• Cooling individual components in multi-block configurations

Key specifications

• Materials: acetal (top), aluminum (base)
• RGB compatibility: 5V addressable RGB
• Dimensions: 65 mm x 65 mm x 41 mm
• Design: black and transparent finish
• Application: water block for liquid cooling systems

How to use

Install the water block into a prepared cooling loop following standard liquid-cooling assembly procedures. Ensure mating surfaces are clean and flat before mounting to the cooled component. Secure the block with appropriate fasteners and seals, connect tubing using compatible fittings, and fill the loop with a recommended coolant. Connect the 5V RGB header to a compatible controller or motherboard header and configure lighting through the controller software if available. Perform leak testing and monitor temperatures during initial operation.

Recommendations

Use corrosion-inhibiting or manufacturer-recommended coolant to prolong component life and to avoid galvanic corrosion between dissimilar metals. Regularly inspect seals and tubing for wear, and perform periodic coolant replacement according to coolant manufacturer guidelines. When connecting 5V RGB, verify voltage and header compatibility to prevent damage to addressable LED circuits.
