Alphacool Core Geforce RTX 5090 Solid + AMP Waterblock with Backplate (14730)

The Alphacool Core Geforce RTX 5090 Solid + AMP Waterblock with Backplate is a GPU water block for three Zotac Gaming GeForce RTX 5090 graphics cards with an Nvidia chip. They are the Solid, the Solid OC and the AMP Extreme Infinity. A chrome-plated copper block under an acrylic top cools the card, and the aluminum backplate is in the box.

Compatibility

Alphacool lists these cards for this block:

• Zotac Gaming GeForce RTX™ 5090 AMP Extreme Infinity (ZT-B50900B-10P)
• Zotac Gaming GeForce RTX™ 5090 Solid (ZT-B50900D-10P)
• Zotac Gaming GeForce RTX™ 5090 Solid OC (ZT-B50900J-10P)

The block was designed for one PCB layout, and card makers sometimes revise a board so that a cooler no longer fits later models. Before ordering, compare your card and its part number with the pictures in Alphacool's GPU configurator, or look it up in its Compatibility List for Nvidia cards.

Copper block and terminal

A copper block sits at the heart of the cooler, precisely milled from a single piece. It is complemented by a precisely crafted brass terminal with a nylon cover. Alphacool says the chrome finish enhances the copper cooler's durability and provides a smoother, more radiant surface than traditional nickel plating. The series continues to feature high-quality brass connectors that, in Alphacool's words, ensure optimal quality and safety.

Design and lighting

Alphacool introduces this block in its new series of graphics card water coolers for the latest Nvidia GeForce RTX generation, part of the Core product series. Alphacool has slightly modified the visual design of the GPU water cooler. Its new highlight is a Core emblem placed above the jetplate, which emphasizes the block's affiliation with the series and visually enhances the design. The backplate is specially adapted to the board and covers the entire backside of the copper cooler, ensuring a clear and uniform appearance. Combined with the aRGB lighting, the acrylic allows for even and impressive illumination of the entire cooler.

Flow and testing

Alphacool says the cooler has been completely overhauled technically. The distances between the cooler and the components of the PCB were redefined and tested to optimize cooling performance. The water flow was simulated using what Alphacool calls the most advanced software, then verified through practical tests. These extensive tests are what allowed for improvements to both the cooler base and the jetplate. Alphacool's claim for the series is that these coolers combine the highest quality with exceptional performance. Thanks to an optimized technical design, it says, they deliver outstanding cooling performance and the best possible cooling for this generation.

What the loop needs

The block has four G1/4 threads. Two take the compression fittings for your tube size, which are not in the box, and the other two take the two plugs that are. The lighting connects through a 3-Pin JST plug, and an ARGB adapter is included. Thermal pads, thermal grease, a putty tool, a plug tool, a screwdriver and the PCIe bracket also come with the block.

Notes

• Alphacool asks that the block be used only with clear transparent water cooling fluids. It warns that the particles and additives in Pastel liquids can clog and permanently damage radiators, pumps, coolers and hoses, and that this can void the manufacturer's warranty.
• Remove the original cooler on an antistatic mat and clean the card of thermal paste and pad residues before fitting the block.
