Barrow D5 Aluminium pump reservoir combo LD5HK-V1 w with ATX support, white

The Barrow D5 Aluminium pump reservoir combo LD5HK-V1 w with ATX support in white integrates a D5-series pump with a machined aluminium reservoir and ATX-compatible mounting. It is intended for custom liquid-cooling PC systems where a compact, robust pump-reservoir assembly and secure installation to an ATX mount are required. The unit offers stable coolant flow characteristic of D5 pumps while reducing the footprint compared with separate components, and its aluminium construction provides mechanical rigidity and a clean appearance in white finish.

Advantages

This combo combines a high-performance D5-style pump mechanism with a precision aluminium reservoir to deliver reliable flow control and reduced vibration. The integrated design simplifies tubing and mounting, consolidating two components into a single assembly that supports ATX mounting standards for predictable placement inside compatible cases. The white finish and aluminium body resist deformation and help maintain a tidy, space-efficient layout for liquid-cooling loops.

Suitable for

• Custom desktop PCs requiring an ATX-mounted pump and reservoir
• Compact or mid-tower builds where space-saving pump solutions are needed
• Systems seeking the hydraulic stability of a D5-family pump with integrated reservoir
• Builds prioritizing a durable aluminium reservoir and standardized mounting

Key specifications

• Pump family: D5-series compatible design offering steady flow and pressure
• Reservoir material: aluminium body for rigidity and thermal stability
• Finish: white external coating for a neutral visual appearance
• Mounting: ATX-compatible support for direct installation to ATX mounting points
• Integration: combined pump and reservoir assembly to reduce internal footprint

How to use

Install the unit in an ATX-compatible location inside the case, securing the ATX support to matching mounting points. Connect inlet and outlet tubing to the pump ports according to the intended loop orientation, ensuring all fittings are tightened to prevent leaks. Fill the reservoir with the appropriate coolant, perform a leak test with the system powered off for the pump only (or using PSU jump-start if required), and bleed air from the loop by running the pump at low speed until no air bubbles remain. Verify stable flow and proper orientation before completing full system power-up.

Recommendations

Use coolant formulations recommended for PC liquid cooling and check compatibility with aluminium components. Periodically inspect fittings and tubing for signs of wear or leakage, and schedule routine maintenance such as coolant replacement and system flushing to preserve pump performance and reservoir condition.
