The Corsair XG3 RGB Hybrid GPU Water Block is a revolutionary cooling solution for NVIDIA GeForce RTX 5080, 5070 Ti, and 5070 graphics cards. Its hybrid design integrates a water-cooled copper cold plate for the GPU and VRAM, plus a dedicated fan that actively cools the PCB and VRM—ensuring balanced temperatures across the entire card. With iCUE Link connectivity and 18 individually addressable RGB LEDs, it blends performance with striking aesthetics.
Whether you own an RTX 5080, 5070 Ti, or 5070, the XG3 is engineered to fit. The built-in temperature sensor provides precise liquid temperature data, allowing iCUE to dynamically adjust fan speeds and pump curves for optimal cooling and low noise. The hybrid fan handles the components that aren't directly water-cooled, so you get comprehensive cooling without a bulky full-cover block.
Connect the XG3 into your iCUE LINK ecosystem using a single cable. Control the RGB lighting, monitor temperatures, and fine-tune performance through Corsair iCUE software. The block also includes 18 addressable RGB LEDs that shine through the transparent flow path, showcasing your coolant.
Upgrade your RTX 50-series GPU with the Corsair XG3 RGB Hybrid and enjoy lower temperatures, quieter operation, and a stunning visual centerpiece.

The XG3 RGB Hybrid represents a new approach to GPU cooling, offering the efficiency of liquid cooling with the simplicity of air cooling for critical components. Its slim profile makes it easier to fit in smaller cases compared to traditional full-cover blocks. The iCUE LINK integration allows for a clean, single-cable installation, reducing build complexity. With real-time temperature data, you can optimize fan curves for silence or performance. This water block is ideal for enthusiasts who want uncompromising performance and aesthetics.
It supports NVIDIA RTX 5080, 5070 Ti, and 5070 reference and custom board designs. Check your card's PCB layout against the official compatibility list to be sure.
Yes, it must be connected to a custom liquid cooling loop with a pump, reservoir, and radiator. The fan part is built-in.
You can connect it to a standard ARGB header using an adapter, but full control of RGB and fan curves requires iCUE software and an iCUE LINK System Hub.
The water block cools the GPU and VRAM directly, while the fan cools the VRM and other PCB components, preventing hotspots and reducing overall temperatures.
Installed this on my RTX 5080 and temps dropped by 30°C under load. The hybrid design is clever – the fan helps cool the VRMs. iCUE Link made wiring a breeze. Looks killer with 18 RGB LEDs.
The block is hefty and well-machined. Included thermal pads are pre-cut, so installation was straightforward. The RGB adds a nice glow to my build. My GPU now idles at 27°C and never exceeds 55°C gaming.
Performance is superb – my 5070 Ti runs cool and quiet. But the block is long, so make sure your case has room. iCUE Link is fantastic, though the RGB cable needed careful routing. Overall happy.
I was hesitant about water cooling, but the XG3 made it easy. The hybrid fan really helps, and the RGB integration is perfect. My GPU overclocks higher now. Highly recommend for any RTX 50 series owner.
It works, but installation is not for beginners. The instructions are vague, and I had to redo it twice. Once installed, temps are great. But if you're new to water cooling, consider getting professional help.
The 18 LEDs are stunning, and iCUE Link lets me sync them with my fans. Cooling is exceptional – my 5080 drops from 70°C to 40°C under load. The hybrid design is genius; the fan keeps the PCB cool.
Temps are excellent, and the block feels premium. However, the mounting screws are small and easy to lose. Also, the RGB connector is a bit stiff. But once installed, it's fantastic. Would buy again.
The description said it fits RTX 5070, but the mounting holes don't align with my card. I had to return it. Double-check compatibility before buying. Support was helpful, but the product didn't fit as advertised.
My 5080 runs at 45°C under heavy load now, and the RGB is blindingly beautiful. The hybrid cooling is overkill but awesome. Installation took a couple of hours, but the result is worth it. Best purchase for my PC this year.
