  • Completes any high-end build
Style: iCUE XH305i RGB PRO Color: White
Prior to install, my CPU was running near 87 Celsius during CINEBENCH R23 benchmark. I had to pull back voltage, and thus had to pull back MHZ. My GPU was running around 85 Celsius during intense game play. Now, after installing this monster cooling system, my CPU is running at 78 Celsius during CINEBENCH R23, and my GPU is running at almost the same temp +/- 2 degrees. They both idle at 34 degrees Celsius! They used to idle at 50. I was able to now overclock without any voltage issues causing thermal throttling. I went from a CINEBENCH R23 score of approximately 28000, to 31,940. Worth every penny. However, the included saw isn't great. Get an upgraded tube cutter and buy a few extra tubes. You'll be happy you did. I did add one more radiator and set of fans because of the stress my system goes through, but you should still get quite a reduction in temps with only the one set included. ... show more

  • Good product to start with?
Style: iCUE XH305i RGB PRO Color: Black
The items arrived in the box fine, but the CPU cooler didn't light up the RGB tried to return just that but they wanted me to return everything and was already in the build, so I just ate $80 dollars and bout the CPU cooler new. (The CPU cooler worked just not the RGB)

  • Nice kit but...
Style: iCUE LINK XH405i Color: Gray
OK so, my biggest issue is that the CPU water block LEDs just died out of nowhere, this was maybe a month into having everything running fine. Updated my ICUE link software, rebooted and they just never came back on. The water block no longer showed up in ICUE. The durability of Corsair has alway been one of the reasons I go with the brand, so this made me sad. It still worked find, no leaks or cooling issue, but my beautiful RGB is gone :( I've used corsair for my RAM needs doe 20 years, I've never even bought another brand in that time. So I usually trust the brand deeply, I wanted to hard line my PC and found this kit. If you're going to do this and it's your first time, please go watch some videos on it first. Buy more tubing than you needs Lol. Anyway to the product review. The radiator is HUGE. Gotta make sure you have a case that can support the 360mm beast and have room for fittings. The pump is quiet, and performs really well. The mounting can be a little weird but it's not bad ounce you figure out which screws and mount to use. The tools that come with this kit get the job done, but you will need a heat gun, they are super cheap at harbor freight, think it was less than $20usd. This is for someone who really enjoys doing DIY type of things. Performance is great! My temps on my cpu went from 80-90 sometimes close to 100°C down to 28-56°C on this 12900k i9, which is a bit of a hot running cpu. Uploaded some pics. ... show more

  • Get the Icue Link version instead...
Style: iCUE XH305i RGB PRO Color: White
I love the whole setup, it's gorgeous, and it looks amazing. I was surprised by how much fluid the tank can hold. I would reccomend using the clear coolant that comes in the kit. As you can see here, I purchased the purple coolant and you can see how it discolors when the LEDs are turned on. The reason I think you should go with the iCue link is I hate the mess of wires on the iCue commander. To me, the extra $200 would be worth the cable management. ... show more

  • This is a great custom cooling kit
Style: iCUE XH305i RGB PRO Color: Black
The media could not be loaded. This comes with almost everything you need for a great custom loop. I would recommend buying some extra tubing if you want to experiment with bends or if you are new to rigid tubing. It would have been nice to have a drain valve added to the system for the price you pay, since it's an all in one kit, and fitting from Corsair are pricey. ... show more

  • Excellent kit
Style: iCUE LINK XH405i Color: Gray
It gets you started and it has high quality items in there. Just be aware that the hardline tubing pieces that come with it are fairly short so order an extra set just to be on the safe side.
