## Summary description

Alphacool Reservoir ES 2U is a computer liquid-cooling reservoir designed for use with VPP/D5 pump systems and equipped with an integrated flow and temperature sensor. It monitors coolant flow and temperature directly in the reservoir, enabling safer operation and easier diagnostics. Suitable for custom PC water-cooling loops where reliable measurement and pump compatibility are required.

## Long description

Alphacool Reservoir ES 2U with VPP/D5 Flow and Temperature Sensor is a dedicated computer liquid-cooling reservoir designed to integrate with VPP/D5 pump systems. The reservoir includes an integrated flow sensor and a temperature sensor that monitor coolant movement and temperature directly at the reservoir location, providing continuous measurement for system diagnostics and operational safety. Its form factor and ports are intended for custom PC water-cooling loops where pump compatibility with VPP/D5 units and accurate monitoring are required.
Advantages
The built-in flow and temperature sensors allow real-time monitoring without additional inline components, reducing tubing complexity. Designed for VPP/D5-compatible pump tops, the reservoir simplifies mechanical and hydraulic integration into existing pump setups. The placement of sensors in the reservoir provides a stable measurement environment and simplifies leak checks and maintenance planning. The unit supports reliable coolant circulation oversight, enabling quicker identification of flow interruptions or thermal anomalies.
Suitable for
 Custom desktop PC water-cooling loops using VPP or D5 pump systems
 Systems that require direct flow and coolant temperature monitoring
 Environments where simplified tubing and sensor integration is desired
 Builds that prioritize easy diagnostics and routine maintenance
Key specifications
 Compatibility: designed for VPP/D5 style pump integration
 Sensors: integrated flow sensor and integrated coolant temperature sensor
 Installation format: 2U reservoir form factor suitable for common mounting scenarios in custom cases
 Connection interfaces: multiple inlet/outlet ports arranged for pump and loop plumbing
 Material and finish: transparent reservoir body for visual coolant inspection
How to use
Mount the reservoir in a location compatible with the 2U form factor and connect the VPP/D5 pump according to the pump top and reservoir port orientation. Route inlet and outlet tubing to the rest of the loop components, ensuring secure fittings and correct flow direction. Connect the sensor outputs according to the system or controller documentation to enable flow and temperature readouts. Fill the loop with coolant and perform an initial leak and flow test while monitoring the reservoir sensors to confirm correct operation.
Usage recommendations
Regularly inspect the transparent reservoir body for signs of contamination and check sensor readings to detect flow reductions or temperature deviations early. Use manufacturer-recommended coolant types and maintain proper coolant levels to ensure accurate sensor measurements and long-term reliable operation.
