The CORSAIR Hydro X Series iCUE Link XH405i is an all-in-one hardline water cooling kit that brings the prestige of custom loops to your PC. It includes the XC7 Elite CPU water block, XD5 Elite D5 pump/reservoir, XR5 360mm radiator, three QX120 RGB fans, and all necessary fittings and tools for tube bending—everything you need to build a gorgeous, high-performance cooling loop right out of the box.
This kit is designed to simplify the custom cooling experience. The iCUE Link ecosystem connects all components through a single System Hub, reducing cable clutter and making installation straightforward. You get all the premium parts, plus tube bending tools and extra fittings for expanding to GPU cooling later (GPU block not included). It's perfect for enthusiasts who want the look of hardline tubing without the guesswork.
Revolutionary iCUE Link technology powers and controls all components through a single port on the included System Hub. A 4-Way Signal Splitter allows flexible configuration options, and the system automatically adjusts pump speed based on coolant temperature for optimal performance and quiet operation. With 148 individually addressable RGB LEDs across the CPU block, pump, and fans, your build will stand out with stunning lighting effects.
The D5 pump delivers superior cooling performance, efficiently moving coolant through the 360mm radiator to keep your CPU temperatures in check. The included temperature sensor enables automatic adjustments, ensuring your system stays cool under load while remaining whisper-quiet at idle. Whether you're overclocking or just want the most visually impressive PC, the XH405i delivers.
This kit includes the CPU water block, pump/reservoir, radiator, fans, fittings, tubing, bending tool, and cutting tool. You'll need to provide a compatible GPU block if you want to cool your graphics card, but extra fittings are included for that expansion. Check the specifications for the full list of included items.

This kit has everything you need for a custom loop. The quality is top-notch, and the installation was easier than I expected. The hardline tubing looks stunning. Highly recommend for enthusiasts.
This kit is excellent quality, but hardline tubing is not for beginners. It took me a few tries, but the result is worth it. The iCUE Link makes setup easier. If you're patient, go for it.
My CPU temps dropped significantly with this kit. The water block is efficient, and the pump is quiet. The visual effect is amazing. It's a bit pricey, but for a premium cooling solution, it's worth it.
The cooling performance is great, but I had a leak from a fitting. I had to reseat it, and it's been fine since. Make sure to check all connections. The included tools are handy, and the instructions are clear.
This kit saved me a lot of time sourcing parts. It comes with high-quality fittings, tubing, and the water block. The iCUE Link simplifies cable management. My build looks professional. Absolutely love it.
I bought this thinking I could install it easily, but it's complex. The hardline bending is difficult, and I almost gave up. The performance is good, but I probably should have gone with soft tubing. If you're new to custom loops, be prepared.
Corsair has outdone themselves. The components feel premium, and the thermal performance is excellent. The iCUE software allows precise control. The hardline tubes look awesome. It's a bit pricey, but you get what you pay for.
This kit is great, but installation took me the whole weekend. Bending hardline tubing is fiddly, but the included bending kit helped. The end result is gorgeous and my temps are great. Just be prepared for the effort.
I've built many PCs, but this water cooling kit is the best. The iCUE Link makes it easy to monitor and control, and the performance is outstanding. The aesthetic is sleek. Worth every penny.
