Easy to install. It's popular enough that there's step by step YouTube videos (not that it's that complicated). It does have preinstalled thermal compound. Don't take the plastic cover off until you're ready to mount it. I thought there may be another layer of protection like a sticker after taking off the large plastic cover, but there wasn't. So I had to carefully mount the radiator trying to keep the compound protected. Once installed, the fans are simple to daisy chain with the pump RGB and with the included extension cable it was easy to cable manage it and get it tucked in nicely. + Easy to install.

I've front mounted this AIO on my Ryzen 7 5700x, temps stay between 30-40 idle and reaching 50-60 under heavy load (gaming or using music software). However I did use my own thermal paste, rather than the one that comes with the product, so my temps may differ from others. With that being said, this is a great product at keeping my cpu nice and coooool!

Keeps my 9600X at under 45 Degrees at idle and under 60c at load.
Included fans are fine, and the ARGB on block and fans is a nice touch at this price range.

I will be upgrading to a 9800X3D soon, so it will be interesting to see if it performs at around the same level on a TDP of 120 Watts compared to 65. Keeps my 9600X at under 45 Degrees at idle and under 60c at load.

Corsair is always releasing bangers after bangers, this is no different.
Installed this with my new custom desktop, and super easy to install. Cables are always a pain but if you do it right then it works like a charm.
The radiator is very large, so make sure your case can fit it, otherwise you might need to do what I did and remove a fan, install this radiator and reinstall previous fan. Corsair is always releasing bangers after bangers, this is no different.

I recently upgraded from the intel stock cooler to this AIO and the cooling difference was insane, I went from a 65 Degree idle to a 30 degree idle, and a maximum of 55 degrees on high-end games.
