Corsair H100i RGB PLATINUM AIO Liquid CPU Cooler,240mm,Dual ML120 PRO RGB PWM Fans,Intel 115x/2066,AMD AM4/TR4

This is the smaller radiator, and 2 fan unit. There are bigger radiator models and some with 3 fans. I got the NZXT case that has a place in the top to mount this, and it works beautifully. I got the Ryzen 9 16-core CPU, and it recommends the bigger radiator, but they were out. After using this for a while I can say this one adequately manages the heat from the CPU without any problems. It comes with the heat transfer paste on it, but I never trust that, and add my own, just to be 100% sure. I have used these Corsair coolers on my last two serious computers and they have never failed me, never let me down. This one has lights which sync with Aura or other apps, and you can make it flash red if the heat gets too high or something, but I’ve never seen it even get really warm, let alone too hot. Forget a fan, protect your expensive CPU. The cooler they run the longer they live. People say it’s ideal to run warm, not hot, that’s NOT TRUE. The ideal temp for any CPU is -40C, but the burnout is usually >120C, and you don’t want to go above 80C much for longevity of the device. I shoot for 60C as the max on my system and with these coolers I have no issue. The software makes its easy to set curves and performance modes, and keep it running really cool, which is what I do.

I wasn't sure what to expect after reading some reviews. But I had recently bought a Obsidian 1000d case and really liked it. So I bought this to go with it. I must say, I am not disappointed. It's a very nice looking cooler, and is quiet if you know how to setup the fan profiles. It's very easy to install. Mind you I had a socket 2066 and it was very easy for that. YMMV on other sockets. It cools on par with the Noctua NH-D15S I had. I really liked it, but it was so big it blocked my RGB memory modules and was a pain to remove the fans as I had to remove the video card to get to the clips. This is much nicer and cleaner looking. There are a lot of wires coming off the water block, but in my case with my motherboard I was able to hid them relatively easy. I have my I7 9800x OC'd to 4.3GHz on all cores with 2 at 4.6GHz and it keeps temps in the low 80's for the cpu package and in the 70's for each core. Wonderful cooler. Would highly recommend. Fingers crossed for no leaks.

Effective, cheap, and stylish.

This being my first experience building a PC with liquid cooling, I was a little nervous about installation. However, it turns out this is one of the easiest to install AIO units on the market, with excellent cooling performance. With RGB lighting on the fans and the pump head that I can synchronize with other Corsair RGB products, it makes custom lighting really easy. My computer is now quite the showcase, and when I added a Corsair RGB mouse, I was pleasantly surprised to see the software immediately recognize it and allow me to easily adjust lighting and other settings. Best part of this cooler is the 2 large fans that float on a magnetic field, making them very smooth and quiet. The one drawback is that the pump comes with thermal past pre-applied with a loose-fitting plaster cover to protect it during shipping. The cover of mine fell off during unpacking, and it could have been really easy to accidentally wipe off some or all of the thermal paste. Just be really careful when you take it out of the box and you'll be fine - or wipe it off and apply your own if you prefer. Overall, I would buy this product again and highly recommend it.

[UPDATE] 2021: Transferred my system to a Corsair 5000D, which has better airflow but just reaffirms the pump noise. It's not a big deal until everything quiets down with my quiet fan curves and all i can hear is the pump. The iCue Quiet profile for it sounds like a low droning sound, while the Standard profile sounds high pitched. The fans are fine, the sound they make are more on the "whoosh" sound and are acceptable in high loads. Temps are still fine. NO, THE LED's DONT MAKE THE SOUND. Turning the LEDs on or off doesn't make any difference for me in loudness and temp. Also, the pump itself have blown out its blue LEDs. If i set lights to blue or white, it will just turn yellow. If i set to some rainbow effect, blue will not be visible Overall, it's still fine in cooling. It's bothersome mostly when not gaming and it's quiet all around. I'd probably take off half a star at most if i could. ------------------------------------------------------ Works well, temps acceptable. I learned to like the iCUE for how it's standard fan controls work for this. It's not as noisy as an old 240mm Corsair H100 on an i7 3700k that i had a long time ago. [UPDATE: however, the water pump in standard iCUE profile is the noisiest part, had to set it in the quiet profile. Still works without temp problems.] LED control works well. Didn't really need the LED as i don't have a visibly open case but price difference between this and the nonLED was negligible at time of shopping (and i was staring at one in a Microcenter that was priced way higher). Connected power as per manual instructions. Main power comes from SATA power cable. Connection to motherboard CPU fan header is not the main actual power and fan control. You just connect it probably to satisfy the motherboard need to have something powering a CPU cooler. The fans themselves connect to the pump and the pump has to connect to an available USB header (USB 2.0 or 3.0 [or 3.1 gen1]) for iCUE control. It fits but I cannot recommend this to anyone with the old Corsair Obsidian 550D case, which i have. I almost considered replacing either this or my case, which i was trying to avoid. It only fits one way on the top exhaust with the tubes on the rear side of the case. Its fine at first until the motherboard (ASUS ROG Maximus XI Hero (Wi-Fi)) and the PSU-to-CPU power cable comes into play. It basically shouldn't fit. Specifics: The 6-pin and 4-pin CPU power cables from PSU would be crammed in tightly once the H115i is installed. The HX1050 PSU does not have flexible cable tips. The clip or hook that holds the CPU 6-pin power cable to the motherboard was preventing me from physically installing the H115i. Also, the top heat sink shroud of the mother board is uncomfortably close to one of the H115i fans. My "fix": I used a wire cutting pliers to cut the hook off of the CPU 6-pin that clips it into place. After installation, the H115i's fan frame is literally sitting on top of the connected 6-pin. I hoped that even when the CPU cables were stuffed and bent to their limits, they will not cause any shorts, and they don't, as far as i can tell. I am just living with the fact that fan blades are just 1 to 2 mm away from the shroud/heat sink thats on the top part of the motherboard. CPU: i9 9900K not overclocked as chip lottery wasn't good to me and i don't want to have to deal with indepth OCing nowadays. Im getting old and not getting richer. Just have XMP set up, fan curves tuned and everything is low noise, fine and dandy. HWMonitor will show that the cores would sometimes peak 5001 MHz anyway (on some non-gaming/non-benchmarking computing)

*******Edit 5/29/2019 I had an issue with my unit in which the H115i when updating the firmware. While the update was taking place the H115i disappeared from iCue and remained updating (over 30 minutes) which was irregular as most of the previous firmware updates lasted several minutes. I tried restarting iCue to no avail but the H115i fans started to max out and the pump would go full speed. This was way too loud so I hard reset my computer. To my confusion the pump was recognized by iCue on restart with the pending update once again. Attempting to update restarted this cycle of a disappearing H115i that would go full blast. At this point I contacted Corsair support and issued a ticket. They gave me some suggestions (plug usb header onto another motherboard header) but this did not solve the problem. At this point they issued an RMA and graciously provided the shipping costs. I thought they would attempt to just fix it but instead sent me a brand new unit. After install, I was able to update to the firmware that borked the previous unit and the pump is working flawlessly. Will update this review if anything happens. TLDR: Firmware update borked H115i but Corsair support came to the rescue quickly and provided a new replacement unit. Not docking a star cause it wasn't the pump that malfunctioned but iCue. If I could give iCue a rating, it'd be a 1 out of 5. Come on Corsair, fix iCue! ********** This is quality all in one (AIO) liquid cooler from Corsair that comes with RGB LL 140 maglev fans that are reliable, quiet, efficient and allow for a lot of colorful customizations for any PC build. I previously owned the Corsair Hydro Series H115i and this is a decent improvement over that model. I purchased the 280mm version of this product and this is the current build I am using it with: Corsair Obsidian 500D RGB Corsair Commander Pro ASUS Maximus Code XI motherboard Intel Core I9 9900k Corsair Vengeance RGB 2 X 16GB 3200 MHz Asus ROG Strix RTX 2080 TI Corsair H115i Platinum Seasonic Prime Platinum 1300W 2 X Samsung EVO Plus 1 TB NVMe 2 X LL 120mm Corsair RGB Fans Build Quality: This is a solidly constructed AIO. The radiator is thick and the tubing is not extremely rigid, allowing for some decent positioning/maneuverability if using as an exhaust or intake. The fans provided are Corsair's LL140mm RGB fans which are maglev and are beautiful to look at. The CPU block has a ring that lights up with RGB lights as well. Now there are a lot of cables to manage with this package as the RGB is connected via a micro USB cable that needs to be connected to a motherboard USB header. Then the fans also need to be connected to the motherboard (or preferably a Corsair Lightning Pro Node or Commander Pro) and the whole thing is powered via a Sata cable. Overall it's a quality AIO but comes with a mess of wires which is somewhat counter intuitive when going for a clean RGB look. Perfomrance: Now I am judging the Platinum's ability to cool my particular CPU and your results will vary depending on what CPU you end up using. Regardless, bare in mind that trying to cool an I9 9900K overclocked (to 5.0 GHz all cores at 1.335v) is really difficult for any AIO to accomplish efficiently. When running CPU stress tests (AIDA64, RealBench, Prime 95), the 9900k will hover around 85-87 Celsius. When gaming however, it runs much cooler mid 50's to highs of 60-65 C. Overall you're not going to be blown away by the performance but you should be able to adequately cool most consumer grade CPUs. Noise: The AIO is very quiet on idle as the both the pump and the fans function at a mere whisper. If you crank up the fans to 100% or put the pump on extreme mode they can get very audible (like a jet taking off). However, you can create custom fan curves to fit your preferred noise-to-performance level using the iCUE software that simultaneously allows for RGB control. RGB Lighting: Both the fans and the CPU block can be customized to the color of your choosing utilizing Corsair's iCue software. You can create custom effects or use presets and can even control the brightness (three levels) of the LED's or simply turn them off. They work well and look great all around. Price: This is somewhat subjective as RGB always commands a price premium. Compared to the Corsair Hydro Series H115i PRO RGB AIO at $138.63 (current price on Amazon), you're paying almost $20 more for the same performance without RGB fans. However, if you take into account the fact that this product has the better LL140mm RGB fans that are quieter and cost $39.99 each, the $!59.99 price tag starts to sound like a phenomenal deal. In my opinion, this product is reasonably priced for what you get. Side Notes: -The Corsair iCUE software is hit or miss. It is buggy and not as easy to configure as it should be. I didn't factor this into the review rating because the software works with many products and doesn't actually reflect the AIO's quality in itself. That being said, to fully utilize the RGB you will have to use the software no matter what. -Extra screws, RGB cable extensions, and fan cable extensions are included in the box.

Quality components, feels really substantial and well made. Icue is not my favorite but I guess it’s not the worst program out there. But I truly do not like it very much, it’s hard to use and confusing to find settings quickly, huge learning curve for me. Seems like they could have squeezed more wires into a single cable, rather than have stuff hanging off 3 sides of a 4 side CPU block. Not my least favorite design but definitely they would have done better to have all wiring come out top or side, in my opinion. Lighting is nice, wish it came with LL140 fans though. Wow sounds like I’m complaining a lot here but on the whole I really do like this AIO. It keeps my 5800X nice and cool around 29-31*C coolant temp. (CPU 31*C in HWINFO64) Buy this AIO if you don’t have space/want such a large cooler as a 360 or bigger. It does the job keeping higher watt CPUs cool, but isn’t massive at the same time. Noise could be lower but I can’t hear it over my 3080Ti fans so it really doesn’t matter. Buy it!

I have never built a computer before. With that said, watching an installation video for this unit was all it took for me to get it installed within 30 minutes. I installed this unit after my motherboard, CPU, and RAM were attached into the case. Made it a lot easier to manage the tubes and hide the fan wires. The unit keeps my Ryzen 2600x hovering around 28-32c under idle and about 38-40c when stressing it out on a game using Ultra settings. The fans have 4 modes: not operating, quiet, balanced, and extreme. I find balanced to be the best when it comes to both performance and low noise. The extreme setting is pretty loud and sounds like a box fan turned on medium. The extreme setting cools the processor down pretty quickly though from hotter temps. You can control the colors and the fan/pump through the iCue software.
