Water block Corsair CX-9020030-WW Copper PMMA 60°C

The CORSAIR iCUE LINK XG7 RGB 40-SERIES GPU Water Block is a total-conversion cooling solution for MSI GeForce RTX 4080 GAMING SUPRIM and GAMING TRIO graphics cards. Combining a copper cold plate with a PMMA (acrylic) top, this water block exposes a transparent flow path for coolant and RGB lighting while replacing the factory cooler to reduce overall card size. It supports iCUE LINK single-cable connectivity to simplify cable management and integrate the block into a linked chain of compatible components.

Advantages

This water block provides full-coverage cooling for the GPU, memory, and VRM, with a dense array of over 50 cooling fins to increase heat transfer. The acrylic top plate offers a fully transparent flow path that showcases coolant and RGB effects. Total-conversion design includes a full-length aluminum backplate that protects the PCB. Pre-applied thermal material and thermal pads speed up installation. Multiple connection options and iCUE LINK compatibility allow straightforward integration into custom loops and CORSAIR iCUE-managed systems.

Suitable for

• MSI GeForce RTX 4080 GAMING SUPRIM / GAMING TRIO graphics cards (total conversion)
• Custom water-cooling loops requiring a transparent GPU block with RGB
• Systems where reduced GPU length and thickness are desired
• Builders using CORSAIR iCUE LINK ecosystem for simplified cabling

Key specifications

How to use

Shut down and open your PC, remove the factory cooler from the supported MSI GeForce RTX 4080 card, and follow the included instructions to mount the CORSAIR iCUE LINK XG7 RGB water block. Connect the block into your custom loop using G1/4 fittings (or the supplied connection option), attach the full-length backplate, and hook the iCUE LINK connector into the chain of compatible devices. Fill, bleed, and pressure-test the loop before powering the system. Use CORSAIR iCUE software to detect and control RGB and integrated device settings.

Recommendations

Use only with compatible MSI GeForce RTX 4080 GAMING SUPRIM / GAMING TRIO cards and appropriate fittings. Verify loop integrity and leak-test the system before restoring power. Maintain coolant quality and replace according to your coolant manufacturer's guidance. Follow CORSAIR installation instructions for safe and correct mounting and thermal interface application.
