## Summary description

The Alphacool 15306 upgrade kit is designed for enhancing computer cooling systems. It features a sleek black color and a 1/4" connecting thread, making it compatible with various setups. Weighing 235g, this kit is a reliable choice for improving thermal management in your system.

## Long description

The Alphacool Eisfach D5 conversion kit allows owners of the DC-LT or DDC Eisfach to replace the original back plate with a D5-compatible back. The kit provides the mechanical interface and ports needed to install a D5 pump, giving the system the flow and pressure characteristics of a D5-based loop while retaining the Eisfach housing and visual elements.
Advantages
This upgrade kit provides a straightforward way to convert an Eisfach from DC-LT or DDC pump compatibility to a D5 pump without modifying the main housing. The back plate includes threaded inlet and outlet ports with standard 1/4" threads, designated fill and drain openings, and two 5 mm LED display windows for custom illumination. A built-in Bubble Down unit behind the inlet reduces turbulence and helps prevent air entrainment in the coolant loop.
Suitable for
Users who want to upgrade an Alphacool Eisfach (DC-LT or DDC versions) to use a D5 pump
Custom liquid cooling loops requiring higher flow/pressure from a D5 pump
Systems where retaining the original Eisfach housing and visual features is desirable
Key specifications
Manufacturer: Alphacool
Model / MPN: 15306
Color: Black
Connection threads: 1/4"
Weight: 235 g
How to use
Remove the existing back of the Eisfach unit and fit the supplied D5-compatible back plate in its place. Secure the new back to the housing following the original fastener pattern. Connect the D5 pump to the provided 1/4" inlet and outlet threads. Use the two left-side openings for filling or draining the circuit as needed. Route LED wiring behind the 5 mm display windows if illumination is required. Ensure all fittings are tightened and the loop is bled of air before normal operation.
Usage recommendations
Install the upgrade on a powered-off and drained system. After assembly, perform a leak test and run the pump at low speed while checking for air pockets; top up and bleed the loop until stable flow is achieved.
