GPU WATER BLOCK
Total Conversion GPU water block for your NVIDIA® GeForce RTX™ 4090 graphics card will stand out as a key component of your new water-cooled PC.
An acrylic top plate and transparent flow path puts your coolant and RGB lighting on display.
More than 50 high-density cooling fins positioned over the GPU maximize heat transfer and surface area for lower temperatures.
Total conversion design cools not just the GPU, but your graphics card's memory and VRM as well.
The full-length aluminum backplate completely covers your graphics card's PCB and protects sensitive components from dust and particles.
Pre-applied thermal material and thermal pads make installation quick and easy, with no cutting or spreading required.
Combine with a CORSAIR iCUE controller* and iCUE software for customization and synchronization of RGB lighting across all your CORSAIR RGB products.
*CORSAIR iCUE controller sold separately, alternatively the included ARGB adapter cable can be used for direct control via the motherboard.
Designed to replace your NVIDIA 4090 stock cooler and significantly reduce the size of your new graphics card with a 40% reduction in length, and 60% reduction in thickness.
Reclaim space in your case and beat the heat with a Total Conversion GPU water block*.
*Requires a full custom cooling setup to operate.
