Know before you buy
No, this specific model is precision-engineered exclusively for the NVIDIA GeForce RTX 5090 ASTRAL. It will not fit other RTX 5090 variants or different GPU models due to the unique layout of the PCB.
Yes, the XG5 is compatible with both flexible and rigid tubing. As long as you have the appropriate G 1/4" fittings for your specific tubing size, it will integrate seamlessly into your loop.
Yes, the block includes pre-applied thermal material to ensure optimal contact and heat transfer between the GPU components and the nickel-plated copper base. We recommend verifying that all contact points are clean before installation.
The RGB lighting is designed to be controlled via Corsair’s iCUE software. You will need to connect the block to a compatible Corsair lighting controller to customize the colors and lighting effects.
To prevent corrosion and buildup, it is essential to use a high-quality coolant and avoid mixing different metals in your loop. Regularly inspect your loop for any signs of debris or discoloration to maintain peak thermal performance.
