Water block Alphacool 29145 Acrylic Plastic Black Transparent

The Alphacool 29145 Acrylic Plastic Black Transparent water block is a component designed to provide liquid cooling for computer hardware. Constructed from acrylic and plastic, the unit combines a transparent upper section with black elements to allow visual inspection of coolant flow while maintaining a discreet appearance. At 201 g, the water block is lightweight and intended for integration into custom cooling loops for improved thermal management of compatible components.

Advantages

The water block’s acrylic construction offers a clear view of coolant circulation, while plastic components reduce overall weight and provide impact resistance. Its transparent black finish balances aesthetics with practicality, enabling monitoring of coolant condition without exposing bright colors. The compact and lightweight design simplifies installation and minimizes additional load on mounting points.

Suitable for

• Custom PC liquid cooling loops for CPUs or compatible components
• Enthusiast and small-form-factor builds where lightweight cooling parts are preferred
• Systems where visual monitoring of coolant flow is desired

Key specifications

• Materials: acrylic and plastic
• Color/Finish: black transparent
• Weight: 201 g
• Application: water block for computer liquid cooling

How to use

Install the water block into a compatible custom liquid cooling loop following the motherboard or component manufacturer’s mounting instructions and Alphacool’s recommended torque settings for fasteners. Ensure all sealing surfaces are clean and use appropriate fittings and tubing sizes for a secure connection. After installation, perform a leak test with the loop filled and powered by the pump only; monitor flow through the transparent section to confirm coolant circulation before powering the full system.

Recommendations

Use corrosion-inhibiting and compatible coolants, check fittings and seals periodically, and maintain regular system cleaning to prevent debris or algae buildup that could impair flow visible through the acrylic. Avoid exposing the acrylic to harsh solvents or abrasive cleaners to preserve transparency.
