Now, installation is much easier and more user-friendly.There are no need for 1001 bolts and washers as per their previous mounts.

    Design And Structure


    The Alphacool Core 1 CPU block boasts a high-quality construction that incorporates premium materials to ensure top-notch performance and reliability. The entire block top is crafted from brass, a durable and efficient material known for its excellent heat transfer properties. Complementing the brass top, the cold plate is made of nickel-plated copper, a combination that maximizes thermal conductivity while providing superior corrosion resistance.

    One of the new features introduced in the Core 1 is the innovative 3D printed jet plate located within the block. This jet plate enhances coolant flow dynamics, optimizing cooling efficiency and promoting more effective heat dissipation. Additionally, the block’s dual chamber design facilitates the separation of coolant flows with varying temperatures, further improving the overall cooling performance.

    It is essential to note that Alphacool specifically designed the Core 1 CPU block to cater to the latest platform sockets of AMD AM5 and Intel LGA 1700. This specialized focus ensures seamless compatibility and optimal performance with the most current and powerful CPU configurations.

    The meticulous attention to detail during the milling process results in a flawless finish, with no visible polishing marks on the block’s surface. The outstanding workmanship is a testament to Alphacool’s commitment to providing a product of exceptional quality and precision.

    After some tinkering, I noticed that this robust design does come with a minor complication. Specifically, when opening it, great care must be taken to ensure the 3D jet plate’s O-ring seal is correctly and entirely inserted. Even a slight misplacement of the O-ring can lead to a decrease in cooling performance, potentially affecting the overall effectiveness of the liquid cooling solution.


    Across all five variants, the Core 1 blocks maintain a consistent weight level, showcasing Alphacool’s commitment to delivering a well-balanced product lineup. The non-ARGB model, in particular, weighs approximately 500g, reflecting the careful consideration of materials and design to ensure a substantial and reliable build.

    For those seeking the added flair of ARGB lighting, the ARGB version of the Core 1 is only slightly heavier than its non-ARGB counterpart. The incremental increase in weight is primarily attributed to the inclusion of the ARGB strip, which not only enhances the aesthetics but also allows users to personalize their liquid cooling system with vibrant lighting effects.


    When comparing the new Core 1 blocks to the previous generation XPX Aurora Pro blocks, one notable improvement is their reduced size. Alphacool has designed the Core 1 blocks to be more compact, measuring at dimensions of 72 x 72 x 26.50mm, as specified by the manufacturer. This downsizing not only showcases advancements in engineering but also offers significant benefits during the assembly process.

    With the smaller form factor, users can enjoy a more streamlined and efficient installation experience. The Core 1 blocks take up less real estate in the system, providing better compatibility with various configurations and setups. As a result, system builders can incorporate the Core 1 CPU block into tighter spaces or smaller cases without sacrificing cooling performance.



    To thoroughly test the Alphacool Core 1, we installed it alongside three other blocks on our test bench. The system underwent three consecutive runs of Cinebench R23, each lasting 10 minutes. We recorded the peak temperature for each run and calculated the average from the three readings. This testing methodology ensures a reliable and accurate assessment of the block’s performance under high-performance conditions. Additionally, we ran the test environment on a integrated GPU to eliminate temperature fluctuations from a discreet GPU.
