Vattenblock Barrow Kepler Series LTHOA-04N B silver – CPU/GPU-kylkomponent

Barrow Kepler Series LTHOA-04N B silver is a compact water block intended for integration into custom PC liquid cooling loops to cool a CPU or GPU. Constructed with a silver finish, the block functions as a passive heat exchanger that channels coolant across a thermally conductive base to transfer heat away from the processor. The design suits systems where space is limited or where a low-profile component is required while maintaining steady thermal performance for gaming, workstation, or overclocked builds.

Advantages

The Barrow Kepler water block delivers direct liquid-to-metal contact with a refined cold plate surface to improve heat transfer efficiency. Its compact footprint and silver surface treatment provide corrosion resistance and a consistent appearance within a loop. The component is compatible with standard liquid cooling fittings and mounting solutions, enabling relatively straightforward installation into custom loops without extensive modifications.

Suitable for

• Custom PC liquid cooling loops for CPUs
• Custom PC liquid cooling loops for compatible GPUs
• Compact or low-profile builds where space is limited
• Systems requiring stable thermal control for gaming or workstation tasks

Key specifications

• Function: passive liquid-cooled heat exchanger for processor cooling
• Finish: silver surface treatment
• Form factor: compact, low-profile block suitable for constrained installation spaces
• Compatibility: designed for integration with standard custom liquid cooling fittings and mounting hardware
• Material characteristics: thermally conductive base coupled with a corrosion-resistant finish

How to use

Install the water block into a custom loop following the motherboard or GPU maker’s mounting guide and the loop layout plan. Prepare the mounting surface by cleaning the processor heat spreader and applying the appropriate thermal interface material. Secure the block using the correct mounting brackets and screws, and connect inlet and outlet fittings to the loop tubing. After completing the loop, perform a pressure test or leak test with the pump off and then run the pump with the system powered in a controlled manner to check for correct flow and normal operating temperatures.

Recommendations

Use compatible coolant and corrosion inhibitors recommended for mixed-metal loops, verify threading and fitting types before assembly, and follow routine maintenance schedules: periodically inspect fittings and tubing, top up coolant, and check for sediment or discoloration to maintain long-term thermal performance.
