Reservoir with D5 pump mount

The Alphacool Eisbecher Aurora is a 250mm borosilicate glass reservoir designed to accept a D5 pump body. An embedded 5V digital RGB ring with 12 LEDs illuminates the coolant from below to create the Lighttower water effect. Mounting feet and frames for 120mm or 140mm fan locations are included for versatile installation.

Builders who want integrated lighting

This unit suits custom-loop builders who want a glass tube with addressable RGB lighting and flexible mounting on radiators or fan mounts. It is not for users who need a reservoir with an included pump or a unit that fits a DDC pump format. Buyers who require multiple inlet and outlet ports beyond the standard G1/4 threads should look elsewhere.

D5 pump body compatibility

The reservoir body is machined specifically for a D5 pump top, so the pump format is the single specification that determines fit. Verify that your pump uses the D5 form factor before purchase. The G1/4 thread ports accept standard fittings for hard or soft tubing.

Questions about this item

What does the 250 mm glass tube mean for coolant capacity and loop layout?

The 250 mm borosilicate glass tube gives a tall, narrow reservoir that holds a useful volume of coolant while keeping the footprint small, so it fits in tight cases and makes bleed-and-fill easier.

How does the 5 V digital RGB LED ring connect and what does it control?

The 12 addressable LEDs sit in a ring at the base of the glass tube and plug into a standard 5 V aRGB header, lighting the coolant column from bottom to top with the Lighttower water effect.

Which mounting options are included for the 120 mm and 140 mm fan locations?

The kit supplies feet for floor mounting plus frames that bolt to any 120 mm or 140 mm fan holes, letting you attach the reservoir directly to a radiator or fan bracket.
