The CORSAIR iCUE Link XG3 RGB is a hybrid GPU water block that delivers maximum cooling performance and reduced noise. Its hybrid design directly cools the GPU and memory IC via your custom loop, while an integrated fan handles the circuit board and VRM. This ensures stable overclocking and quiet operation.
Utilizing the patent-pending iCUE LINK ecosystem, this water block daisy-chains with other compatible components using universal connectors, plugging into the iCUE Link System Hub (sold separately). This simplifies installation and reduces cable clutter.
The XG3 is compatible with a wide range of NVIDIA RTX 4090, 4080, 3090 Ti, 3090, 3080 Ti, and 3080 cards. Check the official compatibility list to confirm your model.
18 individually addressable RGB LEDs create immersive lighting effects via CORSAIR iCUE software. Smart temperature control allows precise cooling adjustments through iCUE LINK, giving you full command over your system's thermals.

The XG3 isn't just a water block; it's a complete cooling solution. The integrated fan eliminates the need for separate VRM cooling, simplifying your loop. The iCUE LINK system streamlines wiring and provides real-time telemetry. For enthusiasts wanting the best performance from their RTX GPU, the XG3 is an essential addition.
The XG3 is compatible with many RTX 4090 models, but due to different PCB designs, you must verify your specific card model against the official compatibility list on our website.
It combines water cooling for the GPU and memory chips with a dedicated fan for the circuit board and VRM, providing balanced cooling for all components.
Yes, the XG3 requires the CORSAIR iCUE Link System Hub (sold separately) to connect to your system and control RGB and fan speeds.
Yes, you'll need to remove the original cooler and install the XG3 following the included instructions. This will void your GPU's warranty; check with your card manufacturer.
Yes, via iCUE software, you can set custom fan curves for the integrated fan and monitor temperatures.
Installed it on my 4090 and the difference is incredible. Temps dropped from 70C to 45C under load, and the RGB looks amazing in my iCUE setup. Took me a bit to install but the instructions were clear.
Really good quality, the finish is premium and the hybrid design keeps VRAM and VRMs cool too. Just be mindful that it's not a straightforward loop install – you need to mount the fan and shroud properly. Worth the effort.
My 3080 Ti now runs at 55C max while gaming, and the fan that comes with it is barely audible. The iCUE integration lets me sync everything, and the build quality feels solid. Highly recommend if you're water cooling.
Made sure my card was listed before buying, and it fits. Cooling is fine, but the RGB cable is a bit short and I had to buy an extension. Also, the black coating scratches easily. Decent but not perfect.
This thing is a beast. My 4090 stays ice cold, and the RGB looks sweet through the glass. The hybrid fan actually keeps the rest of the card cool too. Best purchase for my build.
The water block itself is excellent – my 4080 runs at 48C under heavy load. The included fan helps, but the installation process was a bit confusing with three manuals. I had to watch a video. Still, once it's on, it's perfect.
Corsair nailed it. The metal finish, the RGB, the cooling performance – everything is top-tier. It fits my 3090 perfectly and dropped temps by 30C. Worth every penny.
Performance is excellent, and the hybrid approach is smart. My VRM temps are the lowest I've seen. Only complaint is the little fan's cable management – it gets in the way. But once you route it properly, it's fine.
This transformed my rig. GPU idle temps are 30C and load stays under 50C. The hybrid fan is quiet and keeps everything cool. iCUE integration is seamless. 10/10.
I'm a beginner at water cooling and this was tricky. But after a few hours, it works. Cooling is good, though the fan makes a slight hum. If you're experienced, it's fine.
I was worried about compatibility, but it fits like a glove. The hybrid design keeps both the GPU and memory cool, and the RGB adds a nice touch. Installation was straightforward after I watched a YouTube tutorial. My temps are fantastic – 52C max under full load. Definitely recommend.
