## Summary description

Alphacool Eisstation VPP D5 VPP655 PWM is a cooling station combining an external D5-series pump and integrated reservoir designed for custom liquid cooling loops. The unit supports PWM pump speed control for variable flow, simplifies fill and bleed operations, and is intended for PC water-cooling systems where a separate pump/reservoir assembly improves loop performance and maintenance.

## Long description

The Alphacool Eisstation VPP D5 VPP655 PWM is an external pump and reservoir combination created for custom PC liquid-cooling loops. It integrates a D5-series pump with a compact reservoir, enabling reliable coolant circulation and straightforward maintenance tasks such as filling and bleeding. The unit supports PWM control for variable pump speed, allowing users to balance cooling performance and acoustic output when paired with a compatible PWM header or controller.
Advantages
The external pump/reservoir design separates moving components from confined case areas, improving accessibility for filling, air removal and servicing. PWM-capable speed control provides flexible flow management to suit different system thermal loads. The integrated reservoir reduces the number of fittings and connection points required in a loop, and the build is compatible with standard custom loop components for straightforward integration into existing systems.
Suitable for
Custom PC liquid-cooling systems seeking an external pump/reservoir assembly
Enthusiasts who want easier filling, bleeding and maintenance access
Systems where adjustable pump speed is needed to balance noise and cooling
High-performance workstations and gaming rigs using closed-loop custom cooling
Key specifications
External combination of D5-series pump and integrated reservoir
PWM-compatible pump speed control for variable flow
Designed for use with standard custom loop fittings and tubing
Simplified fill and bleed access for maintenance
Intended for PC water-cooling applications
How to use
Mount the Alphacool Eisstation VPP D5 VPP655 PWM in an appropriate external or in-case location that provides secure support and convenient access to tubing connections and the reservoir fill port. Connect inlet and outlet tubing to the loop using compatible fittings, ensuring tight, leak-free joints. Attach the PWM control cable to a suitable motherboard header or fan/controller to enable pump speed regulation. When filling, follow standard loop-filling procedures: pre-fill the reservoir, run the pump at low speed to circulate coolant, and open bleed points to remove trapped air. Verify all connections and perform a leak test before powering the full system.
Usage recommendations
Use corrosion-resistant, high-quality fittings and tubing compatible with the reservoir materials. Monitor coolant level and quality periodically and schedule fluid replacement as recommended for your coolant type. Start with lower pump speeds during initial filling and leak testing, then adjust PWM settings to achieve the required balance of flow, cooling performance, and acoustic levels.
