Water block Aqua-Computer 21871 — acetal/aluminium construction, 94×94×22 mm

The Aqua-Computer 21871 water block is a compact cooling component for custom liquid-cooled PCs. Constructed from acetal and aluminium with a silver and white finish, the block measures 94 × 94 × 22 mm and is supplied as a single unit per pack. It is designed to direct coolant flow over heat-generating components in a liquid cooling loop and to integrate into bespoke cooling systems from Aqua-Computer.

Advantages

The acetal and aluminium construction combines chemical resistance with thermal-conductive metal contact surfaces, while the compact 94×94×22 mm footprint supports installation in space-constrained builds. The silver and white finish provides a neutral appearance that fits a variety of chassis and component styles. Supplied as a single unit, the block is ready for integration into standard custom loops and is suitable for users who require a dedicated water block for targeted cooling.

Suitable for

• Custom PC liquid cooling loops requiring a compact water block
• Cooling heat-generating components within compact or mid-size systems
• Builds where a neutral silver and white aesthetic is preferred

Key specifications

• Materials: acetal body with aluminium components
• Finish: silver and white
• Dimensions: 94 × 94 × 22 mm
• Package content: one water block per pack

How to use

Install the Aqua-Computer 21871 water block into a compatible liquid cooling loop following standard water-cooling assembly procedures: ensure mating surfaces on the cooled component are clean, apply compatible thermal interface material if required by your configuration, mount the block according to the cooling loop layout and tighten fasteners to the manufacturer’s recommended torque. Connect inlet and outlet tubing to the block’s ports using secure fittings and perform a pressure/leak test of the closed loop before powering the system.

Recommendations

Use coolant fluids and fittings recommended for acetal and aluminium components to avoid galvanic or chemical corrosion. Regularly inspect fittings and tubing for signs of wear or leakage and flush the loop periodically to maintain optimal thermal performance.
