Water block Aqua-Computer 21801 — acrylic/aluminium/nickel, 98×98×22 mm

Aqua-Computer 21801 is a compact water block made from acrylic, aluminium and nickel with a silver finish, sized 98 × 98 × 22 mm. It is designed as a single-piece cooling accessory for custom liquid-cooling loops and is suitable for mounting on compatible PC components to dissipate heat. The construction combines an acrylic top with metal materials to provide a stable mounting surface and corrosion-resistant visual finish for loop integration.

Advantages

The water block offers a compact footprint while providing a metal base and nickel plating which support efficient heat transfer and long-term durability. Its single-piece design simplifies installation into custom loops and the silver finish integrates visually with a variety of system builds. The use of aluminium and nickel in external parts reduces the risk of external corrosion and matches common loop fittings and hardware.

Suitable for

• Custom liquid-cooling loops in desktop PCs
• Cooling of CPUs or other compatible components with matching mounting and coolant flow requirements
• Builds requiring a compact water block with a low-profile 98 × 98 × 22 mm footprint

Key specifications

• Materials: acrylic top, aluminium exterior parts, nickel finish
• Dimensions: 98 × 98 × 22 mm
• Design: single-piece water block for liquid cooling
• Finish: silver-coloured nickel surface treatment

How to use

Install the Aqua-Computer 21801 water block into a compatible custom water-cooling loop following the motherboard and mounting hardware requirements of your system. Prepare mating surfaces by cleaning CPU or component heatspreader and apply an appropriate thin layer of thermal compound where required. Mount the block using the correct mounting hardware and tightening procedure for the target socket or component to ensure even contact pressure. Connect inlet and outlet fittings to your loop, verify leak-free connections, and perform a system leak test and coolant flow verification before powering the PC.

Recommendations

Use corrosion-inhibiting coolant compatible with aluminium and nickel components and follow manufacturer guidelines for mounting pressure and leak-testing. If your build requires a specific retention system or back plate, ensure compatibility with the motherboard socket and use the correct mounting parts. Periodically inspect fittings and coolant condition to maintain thermal performance over time.
