The mounting can be done via feet but also directly on a 120 or 140mm fan space or even directly on a radiator. Extensive mounting options There are two basic mounting options that can be used but versatile. The Eisbecher Aurora glass expansion tank has included feet for mounting on the bottom of the case, for example. However, the scope of delivery also includes mounting frames with which the Eisbecher Aurora can also be mounted on any 120 or 140 mm fan location. Thus, of course, mounting directly on the radiator or radiator fans is also possible. Digital RGB lighting Whole 12 aRGB LEDs illuminate the glass tube.

4. Alphacool Core Distro Plate 360 Left with VPP Pump

The Core Distro Plate from Alphacool, featuring the VPP Apex pump, is an essential component for any custom water cooling setup. It significantly simplifies the construction, planning, and maintenance of complex water circuits, and thanks to the pre-installed VPP Apex, no additional pump installation is required.

Core Design
A core element of Alphacool's Core Design series is the chrome-plated G1/4 connections made of brass. In the Core Distro Plate, the connections are recessed rather than screwed into a thread as is usual. This design choice helps Alphacool avoid potential leakage issues caused by cracking from the direct screwing of the connections into the acrylic. The connections are two-part, equipped with an O-ring, and counter each other during installation in the acrylic. This not only ensures absolute sealing of each individual connection but also allows for the clear and functional aesthetics of the Alphacool Core Design series.

Easy Installation
With the help of the included components.

7. Alphacool Cape Corp Coolplex Pro 10 LT

The Alphacool Cape Coolplex expansion tanks have been a well-known presence in the water cooling market for many years.

Even such fundamentally solid products need an update to meet the latest demands. Therefore, we at Alphacool have phased out our last series and are now launching our tanks, newly made from POM under the name "LT" and from full metal in the "Copper Edition." Of course, the tubes are again made from high-quality Plexiglas, which has reliably operated in your PC in the past.

The updates are remarkably simple: In addition to the new colors, an additional threaded opening has been incorporated into the lid of the expansion tank. This makes filling with a fill port easier. Furthermore, this tank can now also be mounted flat! The riser tube, which is normally intended for venting the system, can now be unscrewed, as it is no longer needed when the inlet comes from above. A nice side effect: We now have more space for lighting modules and can showcase our new tank even better! To further enhance the overall concept, all closure screws for both models will be delivered in shiny copper.

Traditionally, all threads are sized at ¼”. Our well-known transparent mounts are also included in the package: This way, the tank becomes a wonderful eye-catcher for your PC under the glow of an LED!

Note: Additional screws are required for installation.
