Water block Alphacool 25669 Black 22.5 W

The Alphacool 25669 Black 22.5 W water block is a compact cooling component designed to reduce temperatures in computer systems. It delivers a rated thermal performance of 22.5 W and features a black finish intended to integrate visually into a variety of builds. The product is suitable for direct-contact heat transfer to targeted components, providing consistent thermal management in small to medium thermal loads.

Advantages

The water block combines a compact form factor with straightforward mounting and a neutral black appearance that fits many case interiors. Its rated heat transfer capacity of 22.5 W is appropriate for cooling lower-power components or as part of a larger liquid cooling loop. The construction and surface finish support reliable contact with cooling liquid and heat sources, enabling steady operation under normal operating conditions.

Suitable for

• Cooling low- to moderate-power components in desktop PCs
• Integration into custom liquid cooling loops
• Compact builds where space and visual coherence are important
• Systems requiring targeted thermal management for discrete components

Key specifications

• Rated cooling capacity: 22.5 W
• Finish: black
• Application: component-level water block for PC cooling
• Form factor: compact, designed for integration into liquid cooling loops
• Material and surface treatment: optimized for thermal contact and fluid compatibility

How to use

Mount the water block to the intended component following the system-specific mounting points and thermal interface material instructions. Ensure a clean, flat contact surface and use appropriate thermal interface material where required. Connect the inlet and outlet fittings to the cooling loop, verify correct flow direction, and perform leak testing before full system operation. Monitor temperatures during initial operation to confirm expected thermal performance.

Recommendations

Use compatible fittings and tubing rated for PC liquid cooling; maintain regular inspections for leaks and coolant condition. Combine the water block with a pump and radiator sized for the overall system heat load to achieve balanced cooling performance.
