      I have one of the newer faster processors, as you may know speed, wattage and processor cores can mean a lot more heat than older slower cpus of the past. I have been using an enormous air cooler in my system but the temps were marginal at best, I wanted something better both to prolong the life of my components and to allow for future overclocking if I wanted to experiment with that. Liquid cooling can be quite an investment for a custom system, I didn't want all that hassle so I started looking at products like this one. Corsair has a fantastic reputation mostly for their RAM products but they make other components as well these days. When purchasing a pre made sealed cooler like this product the first thing you do is make sure your case can accommodate it. The max size radiator my rosewill THOR case can handle is 240mm which is what this product provides but there are larger radiators and also some smaller square units for smaller systems, as you'd expect the bigger the radiator the better it cools. These work just like the radiator on your vehicle, liquid cycles past hot components then is cooled when it runs through the radiator which pulls the heat away by using fans and then it moves back through the loop. This installation was fairly painless, most sites recommend it to be installed in the top of the case with the fans pulling air through the radiator and out the top of the case. Corsair for some reason says you should pull outside air in with the fans and not exhaust case air through the radiator and out the top, I am playing with that one, it's a simple matter to flip the fans over if you want to. The biggest issue is to be sure you can attach the pump to the top of the cpu, the hoses are heavy and a bit stiff if your case has a side window this product has a light on top of the pump and apparently you can get a kit to change that led color if you want to. The unit smacks of quality and the fans are very quiet and move a good amount of air. I am not that concerned with fan noise but some folks might be. You will need only one fan header as there is a splitter for two 3 pin fans. You will also need an internal USB header on the motherboard, you attach a cable to this that has a mini (not micro) usb connector that plugs into the pump to provide power. In the old days I was worried about the concept of water around my expensive components but this product apparently uses some sort of vegetable oil like substance that will not short out your motherboard if it should happen to leak. In reading reviews there are almost no reports of hose/radiator failures but it's probably a good idea to take a good look periodically. All I know is that my cpu temps went from a reported 50+C with air cooling to a reported 19 to 30C under heavy load. There is a software program on the corsair web site that will read the temp sensors all over your motherboard and some components so that you can observe temps, since this product my video card is the hottest component in the case as you may expect. If you don't know, 70C (about 140F) is considered melt down temp for a cpu but most motherboards these days have a thermal detection function that will shut everything down before those sorts of temperatures occur. Of all the sealed coolers I looked at this is the only one with a five year warranty. I'm sure many of the other products out there are just as good but I've come to trust the corsair name which influenced my purchase decision a lot. Last comment, the pump comes with heat sink compound applied but most builders recommend artic silver 5 or newer for the superior heat transfer it provides so wipe off the stuff that comes with it (careful not to scratch the copper surface) and apply a tiny bead to the top of the cpu and use a straight edge like an old credit card and carefully spread the compound with as few streaks and bare spots as possible before you screw down the pump.

      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.

      Tale of caution

      The cooler itself looks awesome, is easy to set up, and performs great under normal circumstances I'd give this four stars. Now to explain why I didn't.. After a few weeks of being in service, one of the hoses on the CPU end decided to pop out.. spraying the internals of my computer. I often leave my system on for extended periods as I run gaming servers for my son and his friends. I came home to find the system on, hose popped out, and a weird maple syrup smell in the room. I contacted Corsair and am waiting for a reply to see what the next recommended action is. I don't have a second cooler to see if my board/CPU is still functional. I'm not touching anything until Corsair fills me in on their procedures. My hope is Corsair handles this properly. Their product failed and potentially may have damaged my two week old I7-6700K CPU and possibly other expensive components. My key questions: What is in the coolant water and how/can it be properly cleaned from a system in this situation? Does Corsair cover the entire system in the even of failure, or do they just replace the failed cooler and expect the customer to foot the bill for any damage caused by failure of their device? I suspect I may just be having a run of bad luck. Most users don't have this issue I suspect. Whether I'd consider this a decent product or whether I'd recommend it to a friend is going to entirely be determined by Corsair customer service. I hear they treat their customers well, so I am optimistic.

      Keeps my CPU Nice and Cool

      Hey, everyone. I recently upgraded much of my Gaming PC, including the CPU. It's now running an Intel i7-7700K "Kabylake" CPU. Before purchasing this cooler from my local Best Buy, I was running into temps that were reaching slightly above 70 Celsius, which was enough to worry me. The Arctic Freezer 7 Pro Rev. 2 that I had been using is an awesome cooler, but NOT for this CPU, apparently. After doing a lot of research on liquid coolers and their risks vs rewards, the different options available, their estimated sizes, etc. I decided that this was my best option. My local Best Buy had them in stock, so I shot over and grabbed on. Installation was quite a bit of work, but that's because I had to disassemble basically the entire PC, even taking out the Motherboard. But, from what I've read, that's normal when installing a Liquid Cooler, since the bracket that mounts it to the CPU has to be attached from the back of the Motherboard. Once the bracket was installed and the PC was put back together, I had to a bit more fiddling. This is only because of how the vents at the top of my case are designed. I had to do a bit of fiddling to get all of the screw holes on the radiator to line up with a hole in the top of the case. Once I got them lined up, it installed without a problem, other than that it's just so massive. Now that it's installed and working, I can say that it's been working absolutely stellar. When I play Fallout 4, which I run at maximized settings and with a series of both HD and 4K texture mods via Nexus Mods, I rarely dip below 60 FPS. The highest temperature that I've seen out of my CPU since installing this is 54 Celsius, which I am absolutely okay with! All in all, I couldn't be happier with this CPU. In fact, the software used to control and monitor the cooler is actually beneficial to me in other ways, allowing me to also monitor a lot of other component temperatures better than other applications I previously used for said temperatures. My only recommendation is that you try to measure the mounting area of your case and compare it to the dimensions of the cooler first, as it is a little large. I imagine it'd be better in a Full Tower rather than the Mid Tower that I have it mounted in, but it still fits (just tightly).

      After reading the horror stories of cooler lines breaking & difficult installs, I was leery to say the least. But I did research & found Corsair redesigned the model with high quality braided hoses. Plenty of length & flex to install in the 2 positions one would normally place it in. The cooler lines now mount in the top of the CPU block & the revamped hoses. Also revamped is the Corsair Link software for controlling the lights & fan speeds. I had a Corsair H60 & H80i, so I was familiar with the way Corsair coolers tend to fit. This was easier than I thought & had it installed in 30 minutes. I needed to replace my H80i due to it blocking airflow to my north bridge, not for any other reason. At 5 years old that cooler is still working fine! Corsair builds quality products & every PC I build has some in it. This cooler left me with no disappointments keeping my AMD 8150 OC'ed to 4.4GHZ at 26c idle 36c full load! For the nay sayers, the product has been redesigned down to the software. It works as well as the higher models for less. With any liquid cooler, care with how the lines are run in relation to the radiator & clearance inside the case all must be taken. This cooler is generally top mounted & the hoses do pivot & flex to a point! On mine, I noticed I needed to move the radiator forward about 1/2" to relieve pressure I was not comfortable with on the lines. The kit mounts quickly to Intel & AMD CPU's, but some case modifications may need to be done to fit this correctly. Corsair won't tell you this, but DO NOT connect the pump to the CPU header!! Many board won't put a full 12v to that plug no matter what. It should go to the SYS fan or power fan connector. If not, adapt it to connect to a nomex. Failure to do so will result in the pump running less than 3000 rpm which will result in poor cooling. You should also replace the stock thermal paste with one of your choosing, as from the factory the spread is too thin or not coating your CPU all the way causing hot spots. Any undertaking like this should be done with some knowledge as the instructions are very general. This obviously will not fit in most brand name PC's.

      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.

      Best Cooler, Awesome Look

      I have had lots of different coolers throughout the years, and I have built many computers. This cooler however, has overcome all expectations that I have had about it. I'm very picky and hard to please when it comes to my computer and the hardware that I install in it. This cooler has not let me down. Many times especially when using the stock cooler, I have tried them out and they just don't perform like I expect them to. They will do their job, but they don't do it great. This time, I figured I would spend the extra money and really get the one I want and know that it is going to do what I need it to do. Not only does it perform exceptional, but it also looks awesome. I have had many people look into the clear section I have on the side of my case and see the cooler and just be amazed at how well everything looks. I spent a lot of time on this system and I have gotten many compliments on how it looks. The ability to change the color of the "Corsair" symbol on the cooler is really nice as well. I have it red to match the rest of my computer. Between my case and this cooler, even under heavy load, my processor never really reaches of 35 degrees Celsius. I have seen it come to 40 a couple of times, but then almost right away you can see it go right back down. I have a monitor on the front panel of my system that shows all of that as it is part of my motherboard. It also stays really quiet, it can get noisy, but that is if you crank everything up. I usually keep it in quiet mode and once in a while when I'm playing crazy games, or doing something that requires the processor to work hard, you'll hear it speed up, but for the most part, you don't hear it all that much. I have a Cooler Master HAF X case which also has a lot of air flow so that probably helps as well, but all together, this cooler has done an awesome job at keeping this processor cool and running at it's best. If you are looking to have a stylish looking computer, and one that you could overclock even. This is what you are looking for, this cooler will not disappoint.

      Bought this to replace a new Liquid CPU Cooler

      I was playing an intense graphics game when suddenly the frame speed slowed to a crawl and before the system just shut down and would not reboot. The immediate suspect was my six-month-old Corsair cpu water cooler. Cover off hand on the pump and the problem was immediately identified. The pump was very hot, the hoses leaving it, very cool. Ten minutes later when the cpu had air-cooled, my six month old computer kicked off and ran until the cpu overheated again. Same symptoms, dead in the water. I attached power to the water pump and tapped it lightly with a screwdriver. It was dead silent and would not start. I replaced it the next day with this new model. Immediately, my computer worked well and has for the last two months. The first part failed after six months. Sad. I have used corsair coolers for years with no problems except an old one which started showing the effects of anti-freeze evaporating around one of the fittings. That pump is now retired too but it lasted eight years, no problem there. This new model was a total disappointment and judging by online ratings, my problem is persistent problem. After the new cooler was installed, I hooked up power to the old part again and, holding the hoses, slapped it into my open hand. Lo and Behold, the stupid thing started working again. It spun up and works fine. Sadly, I don't trust it. I hope Corsair replaces it although it is now doubtful since it works. I never had any problems with the old design. This new design is questionable. The fans are noisy at full speed and the hoses are very stiff. I hope this new one works longer than six months. Already, the cost for this cooler is doubled. Corsair offers a good warranty but who can wait days or weeks without a computer for them to fulfill their warranty. This user can't.
