Alphacool Eisblock Aurora Acryl GPX-A Radeon RX 6800/6800XT/6900XT Reference with Backplate (11944)

The Eisblock Aurora Acryl GPX-A Radeon RX 6800/6800XT/6900XT Reference with Backplate is a GPU water block for AMD Radeon RX 6800, RX 6800 XT and RX 6900 XT graphics cards built on the Reference board. The Gigabyte Radeon RX 6800 XT 16G and the PowerColor Radeon RX 6900 XT are two of them, and Alphacool's list also names the Radeon RX 6950 XT. It cools the card with a nickel-plated copper block under an acrylic top, and the aluminum backplate is in the box.

The block was built 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 with the pictures in Alphacool's GPU configurator, or look it up in its Compatibility List for AMD cards. Two other Alphacool blocks for the same Reference cards are the Eisblock Aurora Acetal GPX-A and the ES GPX-A Radeon RX 6800/XT/6900 Reference Copper/Carbon.

More performance

Alphacool says the Aurora Acryl GPX-A 6800(XT) Eisblock combines style with performance and extensive digital RGB lighting. Its aim during the development of this graphic card GPU block was more of the second: "we wanted to further increase the performance". The first step was to move the cooler closer to the individual components by reducing the thermal pads to a thickness of 1 mm. Next, Alphacool reduced the thickness of the nickel-plated copper block: instead of 7 mm, it is now only 5.5 mm thick. Inside the cooler, the water flow has been optimized as well. Alphacool says all important components, such as the voltage transformers and the memory, are now significantly better and more effectively cooled by the water. In its words, all this ensures a significant increase in cooling performance.

New design

The cooler has been designed so that lighting is more important than on the previous models. The addressable digital RGB LEDs are embedded directly into the cooling block and run along its entire length, so the effect is an illumination of the whole block. Alphacool's way of putting it is that no corner or edge remains unlit by the aRGB LEDs. The new shape is more angular, with all edges beveled. This promotes better light diffusion in the water cooler due to the reflections on these bevels. In addition, they create various contours, which Alphacool says give the EIsblock its very own unique identity.

Copper or aluminum?

Of course, Alphacool only uses copper for its water coolers, and on this Eisblock the copper is nickel-plated. Compared to its predecessor models, Alphacool has improved the nickel plating even further, which it says has considerably increased the acid resistance. For the buyer this means that the nickel should resist flaking. Why does Alphacool rely on copper instead of aluminum? Simply because, by its account, copper has almost twice the thermal conductivity of aluminum and is therefore clearly the better material for water cooling.

Is there anything else new?

The block also relies on Alphacool's new patented stop fittings, which sit flush with the surface of the terminal. The Alphacool logo now sits in the corner on the top. On the front of the terminal you can see the corresponding names of the compatible graphic card types. Logo and names are fully illuminated by the digital LEDs, and IN and OUT are now marked by small triangles. Alphacool finds that they are easily recognizable and fit perfectly into the entire aesthetics of the graphic card water cooler.

Alphacool on this generation

Alphacool describes the Acryl block as a complete redevelopment of the previous Alphacool graphics card water coolers. It says no technical compromises were made, but that the entire technical know-how flowed into the development and implementation. With experience of over 16 years, Alphacool claims the ability to create GPU blocks that represent high quality and fantastic performance. It says that this perfectly describes the Aurora Acryl GPX Eisblock.

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 screw plugs that are. The plug tool for them is included as well. The lighting has a 3-Pin JST connector: the included Digital-RGB adapter goes between it and a digital RGB controller, which is not in the box. Thermal pads, thermal grease, screws and washers also come with the block.

Notes

• Alphacool's note on application: please use the block only in conjunction with clear transparent water cooling fluids. It warns that the particles and additives in Pastel liquids can clog and permanently damage water cooling products such as radiators, pumps, coolers and hoses. This can result in voiding the manufacturer's warranty as well.
• Remove the original cooler on an antistatic mat and clean the card of thermal paste and pad residues before fitting the block.
