Alphacool Core 2 XT 420mm CPU AiO Cooler (14713)

The Alphacool Core 2 XT 420mm CPU AIO brings technology and materials traditionally found in custom water cooling systems into a convenient all-in-one CPU cooler. Designed for high-performance systems that can accommodate a large 420mm radiator, the Core 2 XT combines a NexXxoS HPE full-copper radiator, Core 1-based CPU cooling technology, the Core DC-LT 3 pump, and three high-performance 140mm aRGB fans.

At the heart of the CPU block is cooling technology derived from Alphacool's proven Core 1 series. The chrome-plated copper cold plate efficiently transfers heat from the processor into the coolant, while the integrated Core DC-LT 3 pump provides reliable circulation throughout the system. Operating at speeds up to approximately 3,800 RPM, the pump delivers a maximum flow rate of approximately 2.1 L/min and a maximum head pressure of 1.4 meters. The pump and CPU block are enclosed within a premium aluminum housing, with the aluminum remaining completely isolated from the coolant.

Heat is dissipated through an Alphacool NexXxoS HPE 420mm Full Copper Radiator. Unlike many conventional AIO radiators, the cooling fins, channels, and pre-chambers are manufactured from copper for excellent thermal transfer. The 30mm-thick HPE radiator utilizes 16 cooling channels and an 18 FPI fin structure, providing substantial cooling surface area for demanding processors while maintaining a relatively compact radiator thickness.

Three 140mm PWM fans provide the airflow necessary to efficiently dissipate heat through the large radiator. Addressable RGB lighting adds customizable illumination, complementing the subtle aRGB lighting integrated into the CPU block for a clean and modern appearance.

The Core 2 XT also distinguishes itself from conventional sealed AIO coolers through its serviceable construction. Alphacool incorporates components and design principles from its DIY water cooling ecosystem, allowing the system to be maintained and serviced when necessary. Four G1/4" inlet and outlet connections and a dedicated G1/4" fill and drain port on the radiator further support long-term maintenance and flexibility.

With its large 420mm full-copper HPE radiator, Core 1-derived cooling technology, integrated PWM pump, aRGB lighting, and serviceable construction, the Alphacool Core 2 XT 420mm delivers many of the advantages of a custom water cooling system while retaining the straightforward installation and convenience of an AIO.
