Simple to install and took my frequently heat-locking AMD 8350 (around 70 degrees Celsius) to a normal temp range of 23 to 28 degrees Celsius. It is easily 1 tenth of the sound produced by the old air-cooling heat sink. Word of Warning: You need space for the radiator & the 240mm fans. I did an ad hoc improvisation where the radiator is in the tower, but the fans are blowing air across it from the outside of the tower. Otherwise, I would have needed to remove the heat spreaders from my RAM to fit both inside. Works like a charm.

4.5/5 Great liquid cooler. Saw stable ~38 degree Celsius tempatures for an OC'd cpu @ a modest 4Ghz on full load. Cool little on-board monitoring set up within the pump itself. Plugs directly into a USB header on the mobo. You'll have to download it from coolermaster's site however. Pros: price (picked it up in store for less than newegg would charge even with a coupon) Performance is great Excellent software that monitors everything. LED can change into any color. Any. You go through the color wheel and choose or turn it off completely. Thermal paste is preapplied. Good set up for a plug in and done system. Good set of 120mm fans. Cons: Very stiff hoses. Bending takes some force. Doesn't come with the software driver cd. You have to manually search the software. Plastic hose fasteners. The connection from hose to radiator seems like a weaker grade plastic. (It has held up so far but it is a concern) Radiator finish mars easily.

All said and done it has a aluminum radiator. Not copper. Like Swiftech's AIO coolers. Which I should have just kept waiting until they restocked. don't get me wrong, this AIO is everything it claims. It's just I'm running a AMD FX-8350 and with it Over clocked the fans are at turbo in speed and noise. This is due to the fin structure. They are to close together for the fans to push the air through. Due to the aluminum rad. where as a copper rad. (which transfers heat more efficiently) Can have more space between the fins, creating less static pressure for the fans to push the air. Which in turn allows the fans to run at slower speeds/lower noise. I would rather have a cooler that can be expanded, has a reservoir, and the pump is with the rad./reservoir instead on the CPU block.

I only water cool all my PC’s I build and this is my favorite one of them all! Yea it may not be as fancy or have all the night lights but it gets the job done right and quiet! I have a 6600Knover clocked to 4.8Ghz with this bad boy temps of 60C while playing Battlefield 1 which is a CPU intensive title.

This is the first All in One water cooler I have bought and it was very easy to install and get running. Before you buy this make sure your case has support to mount a 240mm watercooler. Keeps my i7-8700k and my entire case running really cool.

Quiet, perfectly priced, and seeing really stable #'s for a heavily overclocked i7-6700k. The only issue that I had was that the piece that fits on the back of the motherboard with the mounts that the screws on the front side go into was not completely flush with the motherboard. This required me to add some inserts to buffer the empty space between the bracket and the motherboard to make sure the Corsair's cooler was stuck firm on the CPU. This may have also been an issue with the thickness of the gigabyte motherboard. Overall, a great cooler at a great price!

I got a Intel i7-4790K, that before with the manufacturer fan and a 100% of load I was getting 76°C, now the maximum I'm get with this boy is 58°C at room temperature. Also it has a nice look on my build... I recommended 100%...

This cooler has to be the best cooler I have used for any computer I have put together. Keeps the CPUs nice and cool for long periods of gaming like its nothing.

I purchased this to use on an AMD FX 8250e chip, overclocked on a Gigabyte motherboard. Even at significantly higher than normal clock speeds and at higher voltages, this keeps the chip at around 80oF. And it is very quiet as well. I highly recommend this unit.

I have a 4790K clocked at 4.5GHZ and while idle it is running about 30c with an ambient temp of 25c. Under load it will get to the high 50's to low 70's. Great cooler and great price!

I used to own Corsair H100i cooler and it lasted me for 5 years or longer. It got to a point where I wanted a better cooler. I could have re-applied thermal to save money but I like how it already comes with a thermal. I wanted something newer and stronger and better tubing so thus I bought the H100iv2. I want the PRO RGB version. Maybe my next upgrade I will someday. I recommend this cooler if you wanna overclock your computer. It keeps the temps cool. I overclocked my processor i5 3570k to 4.4ghz auto volts and temps never go beyond 50c at all. Great temps!

Super quiet, excelente performance and really good looking CPU cooler. Overall the best bang for your buck at this price point .Another great delivery by Corsair .

Very easy to install and looks great in my case keeps my CPU cool just as advertised

This AIO liquid CPU cooler keeps my overclocked i7-7700k (4.5-4.8GHz, results may vary) nice and cool. The included fans seem pretty good. I turned the stock configuration into a push-pull (Corsair fans in front, Thermaltake Riing fans on back) and I am NEVER concerned about temperature, even as the radiator is the intake for the whole system. Even my GTX 1070 stays at excellent temperatures. I've had it for almost a year now with no issues. Cons: I did have some stripping on the mounting holes as I had moved it several times. Also, it has a chunky, 90 degree micro-USB cable that plugs into the bottom of the actual block to connect to a USB 2.0 header which is used to control the RGB light - which is not exactly ideal with today's RGB ecosystem - a 3-pin fan cable to connect to the motherboard, and a 3-pin fan splitter to connect both included 120mm fans. This makes for three visible cables extending from the CPU. I initially used the attached fan splitter cable, but have since only plugged the cooler into my motherboard's AIO pump port and the fans into the CPU fan header (with external fan splitter cable, not included), leaving a whole cable unused but visible. I have quite a bit of RGB in my system, but this product has no RGB system compatibility (like Asus Aura), and can only be set to one static color. It requires the use of the Corsair Link program to use, which, at the time of writing, is separate from Corsair's CUE program that I need for my mouse and keyboard. Also if you've never heard pump noise, it can be a bit annoying. But it's still generally quiet. Overall: I would definitely recommend this. Good cooling, decently quiet, good price and ease of installation. It looks pretty good too, but the RGB elements are a bit dated, as is the whole configuration itself. But it is reliable and effective.

Complement to my i5 6600k. Setup in a thermaltake level 10gt case on the top vent bay. Pushing my i5 to its thermal and voltage limits I was able to overclock to 4.9 ghz. 4.8ghz stress test for 4 hours stable, and gamed at 4.6 ghz. After heavy gaming for 3 hours my temperature were still nice and cool.

Purchased the ASUS ROG GD30CI DB71 Gaming System, this cooler was recommended by the Geek Squad, and upon research was purchased to help the cooling of this awesome gaming system. It is quiet and does a great job keeping the CPU cool when playing High Intensity Games on my system.

I bout this cooler to keep my cpu cool on a large overclock. 4670k was running around 80c at 4.2 ghz during cinebench. After cooler install I'm now at around 60c at 4.5 ghz. So over all I'm very happy with the results also has cool rbg lighting right on top of the cpu block which is a very nice touch.

Works great on my fx 8350 keeps it very cool on my 4.4Ghz overclock temp goes no more then 45c on the core low temp is 16c when idle. My Pc Specs Amd Fx 8350 4.4Ghz RX 480 gpu 1TB WD Blue Thermaltake 600watt psu Phanteks eclipse p400 tempered glass case

I purchased the h100i v2 for my new Cooler Master Mastermaker 5 Pro case, which the h100i fit perfectly. The stock fans are loud, but do a sufficient job of moving air through the radiator; however, I would recommend you pair this with a higher cfm fan if you plan on overcloking. You get Corsair quality along with RGB, which all ties into their Link application. The Link application is pretty well thought out and isn't difficult to navigate. If you're in the market for a 240mm AIO, this unit won't disappoint you. With any AIO you do run the risk of leaks, which could lead to component or compete system failure. If you can't easily replace your rig, you may want to stick to air cooling, which is much more reliable and achieves similar results.

I purchased this for my fx 8370. At 5.0 mhz overclock my idle temps are in the mid 40s and under full load reach 60c. Makes me happy!
