The Alphacool Eisbecher Aurora reservoir has an integrated pump top for powerful D5 pumps and comes with a VPP655 PWM pump. The tube of the reservoir is made of glass, the D5/VPP pump top and the lid of acetal. The combination of these two materials gives the expansion tank a magnificent appearance. The wow effect is provided by 12 digitally addressable RGB LEDs in the pump top and the Lighttower water effect inside the glass tube.

Extensive mounting options
Mounting option 1:
Stands are included in the scope of delivery, which, among other things, allow the expansion tank to be mounted on the bottom of the enclosure.

Mounting option 2:
Included in the scope of delivery are 120mm/140mm mounting frames, which can be used to mount the Eisbecher Aurora expansion tank as desired on free fan spaces, radiators or on the fans on radiators.

Digitally addressable RGB lighting
12 digitally addressable RGB LEDs illuminate the glass tube of the reservoir. They are mounted in a ring at the lower end of the tube in the transition to the pump top and provide brilliant illumination of the entire expansion tank. In combination with the Lighttower water effect, a very special ambience is achieved. The digital aRGB LED lighting is connected via a JST 3-pin connector and can be controlled with a digital RGB controller (e.g. Alphacool Aurora Eiscontrol, Art.15360) or a digital RGB capable mainboard.

Lighttower water effect
A special water effect is created in the Eisbecher reservoir via the riser tubes. If you do not fill the reservoir beyond the top edge of the riser tube, you get a kind of fountain effect. In this case, the water is pushed out the sides of the riser tube and splashed against the glass tube. Depending on the flow of the circuit, the effect is stronger or weaker.

The VPP655 pump is ideal for PC and other electronics water cooling. The DC pump is equipped with an electronically commutated spherical motor. In a pump with a spherical motor the only moving part is a spherically shaped rotor which in this pump is held in place by a bearing ball made of ultra-hard and wear-resistant ceramic. The spherical bearing of the rotor offers many advantages: For example an increase of bearing play is impossible due to the design, allowing the pump to run quietly and smoothly over its whole lifespan. A separate magnetic shielding of the pump is not needed.
