Customer Ratings & Reviews

I purchased this cooler because the stock cooler on my i7-8700 was letting the temps reach up to 82c and I was not comfortable with that. After the install of this cooler my temps never reach above 47c and even at that temp the fans are very quiet. The Corsair icue software that controls this AIO cooler is very easy to use and lets me adjust fan and pump speeds and also the color of the water block. This is by far my favorite upgrade I’ve done to my pc. Also installation was a breeze considering I had never installed a heat sink or any kind of cooler myself before. Thermal paste is pre applied to this cooler making life even easier. I’m extremely satisfied with the look and overall performance of this cooler.

Under heavy load this keeps my cpu under 52c and idle will hover around 33-35c and just standard pc use are in the 40’s Easy install as long as your case supports the size! I could not roof mount this in an ATX case so it’s front mounted! Well worth the money! Also in the photo are the Corsair LL120 RGB Fans! Equally worth the money as well!

Have had this cooling system on my overclocked i7 for 2 months now, and haven't had any issues. Keep the CPU cool and is very quiet,. Colors are great and go along with my Gygabyte motherboard color scheme

Had issues beforehand with my old cooler and decided to upgrade to a hydro cooler. Since it was my first time building my computer I asked for help with finding the right one and thankfully the Best buy employee was there by my side and helped me pick out the right one! Works great, easy to connect, and quiet.

This is a very high quality piece of equipment. Very easy to install and set up and keeps my CPU about 25c Max

Bought this to replace some overlooked items in my otherwise great pre built 2070 gaming pc. Super easy install with average temp drop of 15 degrees on the CPU! Great product high quality

I am currently using this in my PC streaming build and it is beautiful. I do have to point out that the only thing that is RGB is the pump/logo that sits on the CPU. I will be buying new hydrostatic fans with lights to replace the 2x plain fans on the radiator. The logo on the radiator itself is a nice touch. I'm using Corsair's ICUE software and cannot see any way to sync lights/pattern on the cpu cooler with the ones on the vengeance ram (also corsair) unfortunately. This is kinda a bummer to me but not a deal breaker. There's probably a way to do it, but i'm not seeing it. A bonus is that you can control the fans/pump speeds via corsair's software.

Easy install and keeps my processor nice and cool even oced. It's a great buy and good quality.

I have 2 of these in 2 computers. They work great. However I guess I also need to also water cool the graphics cards, they kept shutting down. These work good though!!!! I had these installed. So,.. yeah the ease of use was good for me. I am still not sure why the 2nd one was installed upside down. I think it was because the Cyberpower PCs didn't use the same motherboards in the same computers.

Keeps my Core i7-9700K CPU ice cold and looks cool doing it

I think this water cooler looked great in my new Ryzen build. The setup for Ryzen CPU's is a bit harder than Intel but is manageable. The best feature about this cooler are the 120mm mag lev fans which are quiet and last longer.

Keeps my R7 1700 oc @ 4Ghz @ 1.35v under 70c while running unigine and r15 at the same time.

Great cooler does the job! Only reason it lost a star was It needed 4 extra rubber washers on the base plate for a correct fit on my asus h370-f motherboard with a i5 8600k.

I got the 280mm one and returned it for the 240mm because it fit so much better in my case

Even on the most stressful games at full load I only hit a max of 40c with this AIO. Defiantly worth the money.

Disclaimer: I bought this as a temporary cooling solution, as I intend on building a custom loop. Plus, I needed something quickly, it was in stock, and it's Corsair. Installation was a breeze on an LGA2066 Core i9-9900X motherboard/CPU. Comes with all the hardware required for push, pull, or both configuration for attaching the radiator to fans/case, plus integrated thermal compound (which I replaced). I attached the radiator to my existing case front fans (Corsair Crystal 570X). Performance is excellent. I ran Prime95 torture test for 40 hours straight on all 10 cores/20 threads, and CPU temps never topped 70C. Idle temps are half that. Fan speeds never went above 1100 RPM, so it's whisper quiet even under full load. Pump RRM was about 2000. Not sure if that varies or not. There are three things that stand out as less than optimal, but not really deal breakers, even though I plan on replacing it. The RGB is for the pump cover only (which is what sits on top of the CPU). Unlike other models, the fans are not lit. For me it didn't matter, because I am using the case fans. But something to keep in mind - 2 RGB fans would cost another $50 or so, depending on model. The orientation of the cover can't be changed. Since the tubing and USB port are fixed, it may be difficult to install with the Corsair logo oriented properly. Again for me, not a big problem. It still looks cool lit up, but it's upside down. That was the best orientation for the USB cable and tubing for the radiator position in my case. Lastly, even though internal USB 2.0 headers support 2 ports (usually via split/dual cables) the cable provided has only 1 plug. For motherboards with multiple USB 2.0 headers, shouldn't be a problem. Mine only has 1 though (the other 2 are USB 3.1 which is a different footprint), and I have another Corsair RGB controller that also requires a port. Bottom line is it's a great cooler, more than sufficient for punishing loads on a 20 core CPU, with some RGB lighting. If you have a beefier CPU like a 36 core 9980X or a Ryzen Threadripper - you might want the 360mm 3 fan version.

This unit was used to replace a hyper 212 cooler fan, and temperatures dropped an average of about 10 degrees on any average task. My I-7 860 processor overclocked never goes above 70 degrees!!... installation was a breeze, and the fan/pump noise is quite acceptable. And add the nice color changing lights on the pump, it makes this water cooler a must on any new tech PC... Highly recommended.

One month into a new build, the Corsair Hydro H100i continues to cool my i7-8700K like a champ. Core temps remain frosty even under load, and it makes a world of difference in terms of how little noise it produces. Installation was a breeze (far easier than installing a heatsink/fan/cooling tower to your CPU, what with the application of thermal paste, etc), and I haven't had any problems at all. I do hear some noise that I'm guessing is air trapped in the loop on occasion, but it seems to go away after the system warms up. The LED is cool, and I am running it through the Corsair Link software to monitor fans speeds and CPU/GPU/MOBO temperatures (though the software isn't necessary, I believe).

using this cooler with my new build and it happens to be my first build ever and I’m happy to say that it’s supper easy to install on my msi gaming plus motherboard and i5 9600k. I haven’t overclocked yet to check temps but again I’m new at this so I’m still experimenting and so far temps are pretty good.

Worked perfectly and easy to install. Love the RGB color capability on it. Keeps my CPU at 30 degrees centigrade. Fans run quiet and you don't even know they are there.
