Details
The Alphacool Eisblock Aurora Acryl GPX-A RX 6750 XT Reference with Backplate is a GPU water block for AMD Radeon RX 6750 XT graphics cards in AMD's Reference Design. It cools the card with a chrome-plated copper block under an acrylic top, and the black aluminum backplate is in the box.

Compatibility
Alphacool lists these cards for this block:
- AMD Radeon™ RX 6750 XT
The block was designed for one PCB layout, and graphics card manufacturers occasionally revise a card so that a cooler no longer fits later models. Before ordering, compare your card and its PCB number with the pictures in Alphacool's GPU configurator, or look it up in its Compatibility List for AMD cards.
The Aurora GPX series
Alphacool presents the Eisblock Aurora Acrylic GPX as a graphics card water cooler that combines style with performance. Two things characterize it in Alphacool's words: extreme cooling performance and an extensive digital RGB lighting. More than a decade of experience and technical know-how have gone into the development, and Alphacool says it did so without making any technical compromises. It calls the GPU cooler a significant evolution of the previous Alphacool model, which has been improved in every area.
More performance
During the development, emphasis was naturally placed on increasing performance, and Alphacool names three steps. First, the cooler was brought closer to the individual components of the card by reducing the thickness of the heat conducting pads. Next, the copper block was also made thinner. Step 3 involves the constant optimization of the water flow within the cooler, where each cooling fin is 0.6 mm thick. The result, Alphacool says, is that all important components such as voltage converters and RAM are cooled much better and more effectively by the water. It adds that the cooling performance increases significantly.
Chrome-plated copper
Chrome-plated copper is the material of the entire cooler. Alphacool says a chrome plating is much harder than a nickel plating and therefore less sensitive to acids, scratches and damage. In its account the risk of chipping, known from nickel plating, is completely eliminated. Compared to the previous models, however, Alphacool has once again improved the type of plating. It says this significantly increased the acid resistance, which should prevent the plating from flaking off. Chrome plating also looks much more homogeneous and gives a shine that Alphacool says nickel cannot achieve. Until now, it adds, chrome-plated coolers have only been used in the industrial sector, in areas where extreme influences act on them.
Why does Alphacool use copper instead of aluminum? It only uses copper in its water coolers. In this case its reason is that copper has almost twice the thermal conductivity of aluminum, which makes it, for Alphacool, clearly the better material for water cooling.
Brilliant design
The addressable digital aRGB LEDs are embedded directly in the cooling block and run along the sides of the entire cooler. Alphacool describes the effect as an illumination that engulfs the whole block, with no corner or edge left unlit. The new design is more angular, and all edges are beveled. Due to the reflections on these bevels, the light diffusion in the water cooler is better. They also create various contours, which Alphacool says give the cooler its very own visual touch.
Thermal paste and thermal pads
The thermal compound in the box is Alphacool's Subzero, with a thermal conductivity of 16 W/mK. Alphacool counts it among the highest performing thermal pastes on the market. The compound does not conduct electricity. Alphacool says it suits high contact pressures particularly well and, with a viscosity of 850000 TF, can still be processed easily. Alphacool Soft Pads 1 mm and 2 mm thick, rated at 7 W/mK, go on the voltage converters and the graphics memory. The pads for the back of the PCB are 3 mm thick and rated at 3 W/mK.
Other special features
The patented screw plugs of the block sit flush with the surface of the terminal. The Alphacool logo, which sits in the corner on the top, is also fully illuminated. On the front of the terminal, the corresponding designations of the compatible graphics card manufacturers can be seen, and of course the addressable digital LEDs light these fully as well. IN and OUT are marked by small discreet triangles. Alphacool says the marks are easily recognizable and fit perfectly into the overall visual line of the cooler.
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. The other two are closed with the two screw plugs that are, using the enclosed plug tool. To control the lighting, the included digital-RGB adapter joins the 3-Pin JST plug of the block to a digital RGB controller such as the Aurora Eiscontrol, which is not included. More digital RGB LEDs can be chained to the remaining 3-pin connector of the adapter. Thermal pads, thermal grease, the screws and washers for the card and the backplate, and an M3x5 screw and nut for the slot cover 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, taking extreme care if it is held with thermal glue. Clean the card of thermal paste and pad residues with a solvent such as isopropanol alcohol before fitting the block.
