1. Alphacool WAK Core Geforce RTX 5090 Gaming/Suprim
Alphacool introduces its new series of graphics card water coolers for the latest Nvidia GeForce RTX generation. Part of the Core product series, these coolers combine the highest quality with exceptional performance. Thanks to an optimized technical design, these GPU coolers deliver outstanding cooling performance.
At the heart of the cooler is a copper block, precisely milled from a single piece and complemented by a precisely crafted brass terminal with a nylon cover. A chrome finish enhances the copper cooler’s durability and provides a smoother, more radiant surface than traditional nickel plating.
The visual design of the GPU water cooler has been slightly modified. A new highlight is the Core emblem placed above the jetplate, which emphasizes its affiliation with the Core series and visually enhances the design. The series continues to feature high-quality brass connectors that ensure optimal quality and safety. The specially adapted aluminum backplate covers the entire backside of the copper cooler, ensuring a clear and uniform appearance. The acrylic, combined with aRGB lighting, allows for even and impressive illumination of the entire cooler.
The GPU water cooler has been completely overhauled technically. To optimize cooling performance, the distances between the cooler and the components of the PCB were redefined and tested. The water flow was simulated using the most advanced software and verified through practical tests. These extensive tests allowed for improvements to the cooler base and jetplate, ensuring the best possible cooling performance for the new Nvidia GeForce RTX generation.

2. Alphacool Ice block Aurora GPX-N RTX 3080/3090 iGame with backplate
The Alphacool Eisblock Aurora Acrylic GPX graphics card water cooler with backplate combines style with performance. It is distinguished by extreme cooling performance and extensive digital RGB lighting. Experience and technical expertise from over a decade have gone into its development, without making any technical compromises. The Eisblock Aurora Acrylic GPX is a significant advancement over previous Alphacool graphics card water coolers, with improvements made in every aspect.
In developing the Eisblock Aurora Acrylic GPX graphics card water cooler, emphasis was placed on enhancing performance. In the first step, the cooler was brought closer to the individual components by reducing the thickness of the thermal pads. In the second step, the nickel-plated copper block was also designed to be thinner. Step three involves the continuous optimization of water flow within the cooler. The result: all critical components.

3. Alphacool 11750 Water block
The Alphacool Eisblock Aurora Plexi GPX combines style with performance and features extensive Digital RGB lighting. Over 16 years of experience have gone into this graphics card water cooler, representing the current pinnacle of Alphacool's product development.
More performance! In the development of the Eisblock Aurora GPX graphics card water cooler, emphasis was also placed on enhancing performance. In the first step, the cooler was brought closer to the individual components by reducing the thickness of the thermal pads to 1 mm. In the second step, the nickel-plated copper block was also made thinner. Instead of the previous 7 mm, it is now only 5.5 mm thick. The water flow within the cooler has also been optimized. All important components, such as the voltage regulators and RAM, are now cooled much better and more effectively by the water. All of this results in a significant increase in cooling performance.
New design! The Eisblock Aurora GPX cooler has been.
