Alphacool Core XT45 Full Copper 240mm Radiator

For more than a decade, Alphacool’s Full Copper Radiator Series has set the standard in liquid cooling performance. Now, Alphacool introduces the first radiator in its Core Series – the Core XT45 Full Copper Radiator. It delivers outstanding cooling performance paired with an elegant, modern aesthetic. The clean contours of the redesigned housing are enhanced by interchangeable side panels – available either with discreet integrated aRGB lighting or in a classic, unlit version.

As with Alphacool’s proven NexXxoS models, all water-bearing components of the Core XT45 Radiator – including the fins, channels, and chambers – are made entirely of copper, ensuring excellent thermal conductivity. Inside, an optimized structure delivers noticeably improved cooling performance: sixteen instead of twelve water channels provide better flow dynamics, while the refined fin design further enhances heat transfer.

The radiator features two G1/4" ports designed in Alphacool’s characteristic Core style. Made from high-quality brass and precisely integrated into the end chamber, they combine durability with a clean appearance. A fill and vent port on the opposite side simplifies maintenance by allowing easy filling and draining of the cooling loop.

Each Core XT45 Radiator comes with two interchangeable side panels – one featuring integrated aRGB lighting and one without. Thanks to magnetic mounting, both versions can be swapped effortlessly and without tools. The aRGB version adds a striking visual accent, making the Core XT45 Full Copper Radiator a true centerpiece in any cooling setup.
