Alphacool Core RTX 5080 ROG Astral Water Block

This Alphacool Core water block is engineered specifically for the GeForce RTX 5080 ROG Astral graphics card. It replaces the stock air cooler to enable liquid cooling within a custom loop. The unit integrates a chrome-plated copper cold plate, a full-cover aluminium backplate and 5V addressable RGB lighting. It is built for enthusiasts assembling a high-performance custom cooling system.

Suited for custom-loop builders

This block fits only the Asus ROG Astral variant of the RTX 5080; it will not mount on reference models or other partner designs. Buyers who need a universal block or who plan to keep the original air cooler should look elsewhere. The G1/4 threaded ports require standard fittings and tubing sized by the builder.

Chrome-plated copper cold plate with G1/4 ports

The cold plate is milled from a single copper piece and chrome plated for corrosion resistance and a smooth finish. A brass terminal with nylon cover provides two G1/4 threads for inlet and outlet connections. This interface determines compatibility with the rest of the loop components.

Questions about this item

Which Alphacool Core water block fits the ROG Astral RTX 5080?

Model 10267 is built specifically for the ROG Astral variant of the RTX 5080 and includes a matching backplate.

What does the chrome-plated copper core do for my thermals?

The single-piece copper cold plate with chrome plating gives a smoother surface than nickel, improving contact and heat transfer to the liquid loop.

What does the G1/4 thread limit in my loop design?

Standard G1/4 ports accept any G1/4 fitting, so tube size and bend radius are set by the fittings you choose, not by the block.
