Being Asus’ flagship GPU means its performance is unquestionably among the best, if not the best, you will see in the market. Such high performance generates a significant amount of heat that must be managed effectively. Therefore, a GPU water block designed for efficient cooling is essential, and the Hydro X XG5 RGB 5090 water block was made specifically for that purpose. Its full-coverage design, featuring 67 high-density, CNC-machined cooling fins positioned directly over the GPU, maximizes thermal transfer and surface area for effective cooling and optimal performance.

The Hydro X XG5 RGB 5090 water block has a great design, but its build quality really sets it apart. The part that covers the main components of the graphics card is made of nickel-plated copper. Copper is well-known for its excellent heat transfer, making it perfect for efficient cooling solutions. However, bare copper can oxidize over time, which can reduce performance. The nickel plating acts as a protective layer that prevents oxidation and corrosion, ensuring the water block lasts longer and stays reliable. This combination allows for top heat transfer while keeping the cooling system's integrity intact.

And like most CORSAIR PC components, the Hydro X XG5 RGB 5090 Astral water block is also equipped with RGB LEDs that you can customize to any lighting effects you want. It has a total of 16 individually addressable RGB LEDs integrated directly into the GPU water block, so you can program them to display your preferred color theme and effects, allowing you to create stunning visual displays that can sync with the rest of your PC components' RGB lighting, creating a more immersive gaming experience. This feature enhances the overall ambiance of a setup, making it not just functional but also visually captivating.

To enhance the RGB lighting’s appeal, the top plate of the Hydro X XG5 RGB 5090 Astral GPU water block is made of acrylic, allowing you to see the RGB effects through its transparent surface. Plus, the see-through top plate allows you to view the entire water flow while your PC is running.

CORSAIR products have always focused on versatility and broad compatibility, especially with RGB lighting solutions. There are three ways to power the XG5 RGB 5090 ASTRAL water block’s RGB. You can easily integrate it into an iCUE LINK ecosystem via the iCUE LINK System Hub or an iCUE RGB controller, like the COMMANDER CORE XT (both sold separately), using the included iCUE LINK GPU RGB adapter to fully unlock the water block’s RGB lighting features via iCUE Software.

But, for those who wish to utilize their motherboard’s ARGB control, it comes with a 5V ARGB adapter, providing flexibility to use the motherboard’s lighting control, which supports a wide variety of PC hardware.
