Easy to install. Just plug and keep cool. Would definitely be purchasing another on my next build!

Keeps my 13700k extremely cool even while gaming. Once again, Corsair crushes it with quality. It’s spendy but not sure if you’ll find a better 420mm AIO.

By far one of the best AIO coolers on the market. The H170i is the non-LINK version of the Corsair elite coolers, and like many of Corsair's AIO's, pretty much comes ready to go out of the box. Corsair paired this unit with it's high-pressure line of case fans, instead of traditional PWM fans, and the difference in temps is apparent. These are also their floating magnetic bearing fans, and Corsair is the only manufacturer I know of that has that type of bearing in this price point. One big thing I would pay attention to: This particular model is the 420mm radiator, and not the regular 360mm, so it is only going to fit in larger cases. It will fit fine in a Corsair 5000D (or higher) case, or most full-size ATX cases with 420mm spacers. The only con with this unit is it doesn't have the ultra-flexible cable sleeves like the LINK models, so you can't be as flexible with mounting positions. These units perform much better when top mounted. Bonus; unit comes pre-thermal pasted with Corsair's top tier compound, just don't mess up your initial water block mounting!

It's a great AIO cooler with amazingly quiet fans... until they get just slightly out of balance within a month and start making a grinding noise that will make you double check that you did not mount that 40MB Maxtor drive you found the other day somewhere in there by accident. Of course this is fixable but it's also a giant pain in the bigtoe. The LCD screen is beautiful and the ability to load your own images is nice but the support of animated GIFs really puts every other cooler out there in a distant 2nd place.

Restarted my pc for updates doing a new build, and the pump made a weird loud sound and gave me the pump failure icon. The fans were also a pain trying to install the fans as maybe a hole or two on the rad didn't line up with any orientation of the fans. Barely lasted two days I'd stay away and will be switching to something else.

Works and looks great! I would have given it a 5 start if it wasn't because of the fact that I had to replace the first one I got within a week because the pump stopped working!

overally good but sometimes can feel the vibration tho

Super quiet, lookks amazing and makes my case very chilled. It also comes with a hub so if you have a case with fans you can route them easliy and/or if you want to add anymore.

The LCD screen is neat, the pump seems to be able to be controlled by the finicky Corsair iCUE software

Will Go Great with my New Custom PC Build. Love the RGB Color Scheme.

I bought this unit a week ago, lcd worked for 5 min then got the red triangle. Still works pretty good for keeping the cpu cool, but for the price corsair should step up their products. Good luck getting ahold of some one from corsair...

I want this aio as a white version of itself. Overal it’s good product!
