The Alphacool Core Reservior not only looks stylish with its aRGB lighting, but is also flexible in use due to its compact size. The expansion tank is made entirely of acrylic. A D5 or VPP pump is provided for operation. Due to its compact design, the Core Reservior also fits in small cases. Core design A core element of Alphacool's Core Design series are the chrome-plated brass G1/4" connections. With the Core Reservior, the connections are recessed and not screwed into a thread as usual. This means Alphacool avoids the problem of possible leaks due to cracks forming when the connections are screwed directly into the acrylic. The connections are two-part, provided with an O-ring and counteract each other when mounted in the acrylic. High-quality choice of materials & brilliant lighting Alphacool's Core Reservior is made of high-quality acrylic glass. This allows a clear view of the coolant and a brilliant play of colors thanks to the built-in digitally addressable aRGB lighting. The lighting can be controlled via a digital aRGB header on the mainboard or optionally via Alphacool's Aurora Eiscontrol aRGB controller (item no.: 15360).
