Customer Ratings & Reviews

Bought this about 6 months ago and it has worked flawlessly. It maintains the CPU within 10 to 15 degrees of room temperature. I have two, one on my mothers computer and on mine each works perfectly.

Was having issues with my 9700k getting warm (70c+) during gaming with the deep cool air cooler. Replaced it with this h100i cooler and so far I haven't seen temps above 50c with a 4.9ghz overclock.

CORSAIR - Hydro Series H100i PRO Liquid CPU Cooler 120mm Liquid Cooling System with RGB Lighting - great bang for the buck, the system was overheating and this solved the problem like a champ!

I like that it comes with thermal paste already on the heat sink. Install was fast and easy. CPU temps went way down. Fit inside my full tower case, but might be a problem in a small case.

I pulled up a youtube video to be sure but the install was really smooth and easy even for someone who's never done it. I've had zero problems with it since then and it's working great.

I bought this product in store when my other cooler suddenly stopped working. It works great. Great price as well. Other places online were selling it for a lot more money.

This cooler has been great. I have it configured in a push pull and it’s so quiet and temps never see 45c even while gaming or multi tasking it’s really worth it

Corsair the RGB King... replaced the included fans with the 120 LL fans for greater RGB bling and downloaded the Corsair ique! And no issues cooling my cpu (i9 9900k)

The product is bigger than you might anticipate, so be sure that you have room to mount the radiator and fans before diving in. Also, be sure you plug in your fans and any other power to your motherboard that may be blocked before mounting the radiator. I had to take a couple steps back after forgetting to plug in one power cable. The AIO system gets a lot of flack for being on-par with large fan coolers for a higher price, but I found the size and quietness to be worth the cost.

This is defiantly a must. excellent built quality & keeps my CPU a few degrees cooler than an air cooler, this is the best bolt on if you want to water cool your rig.

Awesome product. current CPU fan die need a replacement fan so I chose this product. Temperature of my CPU decreased and a lot less Fan Noise coming from the computer.

when i bought this i was hitting temps of up to 70c with the upgrade to this great AIO my temps went down to 30c idle and 40-49c under load

It is awesome for gaming I was expecting a decrease of only 10 c but it was 20c so my rig runs no more the 70 while gaming and streaming at the same time

The CORSAIR - Hydro Series H100i PRO Liquid CPU Cooler 120mm Liquid Cooling System with RGB Lighting - Black/Gray, is a great water cooler for any gaming pc.

I had some rgb fans (Corsair LL120s) to replace the fans that came with this and looks much better. Would highly recommend if the RGB is appealing at all

I was looking for a quieter alternative from my Wraith Prism cooler for my Ryzen 2600x, so I opted to this Corsair H100i PRO. Installation was a breeze if you have the pre-installed AMD brackets on the motherboard. Tubing is very sturdy and can be orientated in anyway. Keeps my Ryzen 2600x between 40-45 C when it fluctuates between 4 to 4.1 Ghz via Ryzen Master. and then under 55-57 under load with games running on ultra settings. The only concern I have is replacing the pre-applied thermal paste with something else. It does not cover AMD CPU's well.

I was a little leary on cooling my cpu with liquid cooling but so far this has been awesome. it has dropped my temps 15-20 degrees. I,m very satisfied.

Very quiet high performance AIO. Excellent fans included. Only negative is Corsair's software. Not the greatest experience with the software.

This is a great CPU cooler, the only warning I would give is to make sure that you know where it’s going to go in your case and that it will fit.

I don't know much about computers, but my tech buddy said this is what I needed for my new computer. Hopefully it will last a long time!
