Refrigerador de água Alphacool 25667 preto 54 W 46,5 mm x 79,8 mm x 12,6 mm

The Alphacool 25667 Black water block provides targeted liquid cooling for electronic components in compact and high-performance computer systems. Finished in matte black, the block measures 46.5mm x 79.8mm x 12.6mm and is engineered to transfer up to 54 watts of thermal load through its mounting surface. The design focuses on stable thermal contact and efficient coolant flow to lower operating temperatures of CPUs, GPUs, or other heat-generating modules within closed-loop or custom-loop cooling systems.

Advantages

This water block combines a small footprint with a robust thermal transfer capacity, enabling effective cooling where space is limited. Its black finish provides a neutral appearance that integrates with a variety of builds. Precision-machined surfaces and optimized internal flow channels contribute to consistent heat dissipation and reliable performance under sustained loads.

Suitable for

• Cooling compact CPU or GPU modules in small form-factor PCs
• Custom liquid-cooling loops for single-board computers or embedded systems
• Systems requiring a low-profile cooling solution with solid thermal transfer
• Replacement or upgrade parts in existing water-cooling configurations

Key specifications

• Power handling: up to 54 W thermal transfer
• Dimensions (W x D x H): 46.5 mm x 79.8 mm x 12.6 mm
• Finish: matte black surface
• Form factor: low-profile plate suitable for compact installations
• Material properties: precision-machined contact surfaces for improved heat conduction

How to use

Mount the water block onto the target component using the appropriate mounting hardware and thermal interface material. Ensure the contact surface is clean and apply a thin, even layer of thermal paste if required by the installation method. Integrate the block into the cooling loop with compatible fittings and tubing, verify correct flow direction and secure all connections. After installation, bleed air from the loop and verify coolant circulation and operating temperatures before committing the system to continuous operation.

Recommendations

Use compatible tubing and fittings sized for standard PC water-cooling systems and avoid excessive torque on mounting fasteners to prevent damage to the block or the cooled component. Periodically inspect the cooling loop for leaks and maintain coolant quality to preserve thermal performance over time.
