Corsair iCUE H100i RGB Elite Liquid CPU Cooler (16 Dynamic RGB LEDs, 120mm AF Elite Series FDB Fans, 240mm Radiator, iCUE Software Compatible, LGA 1851,1700, 1200, 115X, 2066, and AM4 Sockets) Black

Pros: Easy setup. I've build PCs for decades but this was my first liquid cooler and it was pretty easy to set up. I've got this front mounted in a Lian Li Lancool 2 Mesh and it destroys my high temps. This thing replaced a Noctua NHU12S. While it should be obvious that liquid would cool a cpu better than air, I'm surprised it made as much of a difference. My temps in games are anywhere from 15-20 C cooler! (And yes, I know how to use thermal paste lol). I didn't use any aftermarket paste, just slapped the coldplate on the cpu with the pre-applied thermal material.

Cons: If you have a big case, the loop might be a bit too small for you and may limit your mounting options. I was barely able to position my tubes down in the front of my case. I do have a 300mm GPU which did interfere a bit, but I made it work. In larger cases or with longer GPUs you might have to turn the tubes up or mount it on top of your case. For most people though, it should be fine.

The software that you need to use for custom RGB is pretty bloated, but you don't -have- to use it. It does have some other features, like temperature monitoring, and you may want to set the cooling / pump to a specific setting with it for example. It has its uses.

Overall Review: Not too bad for a first experience with liquid. I'm def not an expert on AIOs but this one seems pretty good. It did what I needed it to do so I'm happy so far. If it explodes and sprays liquid everywhere and shorts out my system I'll revise the review. Until then, this gets a good review from me.

Pros: Easy to set up
Good lighting and software
Quiet pump

Cons: Ok thermal performance

Overall Review: I would recommend this ONLY if it would fit in your case and not a 360mm. With a room temperature around 26 - 27 Celsius, it will thermal throttle at high loads with a 5800X, which is not a cool CPU. At lower room temperature, it's ok, but doesn't give much room for overclocking potential.
