Know before you buy
No, this specific model is engineered exclusively for the NVIDIA GeForce RTX 4090 Founders Edition. It will not fit aftermarket cards from manufacturers like ASUS, MSI, or Gigabyte, as their PCB layouts differ from the Founders Edition design.
Yes, the XG7 comes with high-performance thermal material pre-applied to the cold plate. This simplifies the installation process and ensures you have the correct amount of material for optimal heat transfer.
While the block is designed for seamless integration with Corsair iCUE, it uses a standard 5V ARGB header. You can connect it to a compatible motherboard or third-party controller, though you will lose the advanced lighting effects and synchronization features provided by the iCUE ecosystem.
The XG7 uses standard G1/4 inch threads. This makes it compatible with the vast majority of custom loop fittings on the market, allowing you to use your preferred tubing size and style.
Yes, the aluminum backplate provides structural rigidity to prevent GPU sag and helps dissipate heat from the components on the rear of the PCB. It is an essential part of the block's design for both cooling performance and card protection.
The XG7 is designed to be user-friendly, but it is still a component for custom liquid cooling, which requires careful planning and leak testing. If you are comfortable with the basics of custom loops, the pre-applied thermal material and clear instructions make this a straightforward installation.
