20-30C Drop and Dead Silent

So far this exceeded my expectations. Going from a Hyper 12EVO I ran about 85C at 4.8Ghz on all 4 cores (i7-7700k). This helps keep ambient temperature inside the case low, and I'm now at 4.8Ghz that peaks at 68C. Yes... I saw at the very worst a 20C temp drop. Granted I did change my thermal paste from arctic silver to MX4 as well, so take that into consideration. It's dead silent even when the fans are at max. It's hard to not be impressed by this baby. Take care of your CPU and I would recommend MX4. It's one of the best thermal pastes you can get that's not electrically conductive. If I had to guess I would say this is about a fifth as loud as my Hyper 12EVO fan at max rpm. It really doesn't even have to spin past 80% max to keep temps below 70C.

Silence is golden

I am a big fan of the H115i Pro. I chose it for the 140mm fans over 120mm versions because bigger is quieter usually. Corsair definitely delivered here. Even at max RPMs (~1150) the ML fans are pretty damn quiet while stabilizing CPU temps at close to 30C. This is taking into account ridiculous Southern California ambient temperatures during the worst of the summer. I'm sure winters will be better. The pump is audible but definitely the quieter part of the setup and I have no real complaints. My dream would be a 420MM version but that's probably just pure excess in cooling. Zero RPM mode is the real reason I bought these things and its exactly as advertised. Under standard loads, my CPU temps are within healthy ranges without the fans running. I am very impressed by that. Corsair Link could be a tad easier to use GUI-wise but its pretty much a cinch to set up. I think the loudest part of my PC atm is definitely the GPU now followed by case fans. I love the piece of mind that my PC is quiet while not being likely to be thermal throttled on the CPU end. Setting it up was very straightforward if a downright a cakewalk as long as the case is accessible enough. I had a much easier time installing these pumps over the stock Ryzen Wraith Spire coolers. The CPU part was tool-less. Directions were a bit lacking in the box but the YouTube how-to videos out there clarify everything. The build quality is excellent. The pump felt a little loose but I have no worries it will come off or break. Minor complaint I would have is the RGB isn't anything to write home about. The Wraith Spire cooler was much brighter than it's replacement in my case. I love seeing the grille honeycomb pattern at the top of my case against the walls but they are much less visible now. I am not an RGB person so this is very minor to me as it does its primary job very well. A big plus is that you can set up the RGB to glow based on CPU temperatures. You can tell what the temperature range is based on the color as well have it do different styles like breathing. Very useful and nice. Just wish I could see it more in a dark room with my monitor turned on. I don't have my case facing me so its why its less visible for me. This is my first water cooled setup and it is definitely very positive. I can't compare it to the competition but I would personally recommend this 100%. The packaging itself felt very premium and Corsair delivers on giving the quality feel. Great company as I've dealt with their warranty system before. I think there's a lot of peace of mind for purchasing this. Sorry if I sound like a paid shill but I'm not haha.

EXCELLENT temps, even on delidded OC'ed 9900K, near silent, iCue is good, new pumpndesign is GREAT!

WOW, I did NOT think this would adequately cool an OC'd 9900K based on my experience with a Corsair H100iV2... I was considering a custom loop. I was DEAD WRONG! My system is a delidded 9900k, with Conductonaut liquid metal between silicon and IHS, and Panasonic soft PGS graphene between IHS and this H150i AIO cooler, NOT paste. I've used Gelid GC Extreme, AS5, and MX-4 in the past. Graphene does within 2c of a perfect paste job of Gelid GC, AND keeps temps even across all cores, within 3c of eachother, which is what graphene does best. My CPU is delidded with liquid metal and and OC's VERY well at VERY low voltages. Latest gen Asetek pump design is great; idles cooler, max temps are lower, less pump noise vs last gen in the H100iV2. System specs below. I run it at 5ghz all core 1.283v AVX-2 normally to keep temps under 80c. It hits 80c gaming, benchmarking, or exporting at 5.1Ghz no AVX. 9900k 5ghz, AVX-2 at 1.283v delidded 9900k 5Ghz, no AVX, 1.312v delidded Corsair H150i AIO with 3x Corsair ML fans Asus Maximus XI Formula mobo 32GB G.Skill 3466Mhz CL16 RAM Samsung 960 Evo NVME 1TB boot 4x Samsung 850 Evo 1TB SSD in RAID5 EVGA 2080 Ti Black Edition GPU Corsair HX850i PSU Cooler Master HAF 932 case (oldschool) All temps averaged, delidded with LM between silicon and IHS.

Amazed it keeps the 9900K this cool, and i am not throttled (current/power/turbo boost time maxxed/IA AC&DC loadline 0.01) in any way, LLC5, CPU current limit 140%. Took a few days to dial it all in, i test with games and 4k/8k exports. So far passed everything including prime95 12 hrs run. I aborted P95 run with H100iV2 due to 87c temps within 10 minutes, H150i stayed under 83c at 8 hours, good enough for me. Anything over 85c for CPU is no bueno in my opinion. Also used/tested a Gigabyte Pro Wifi mobo and MSI MEG mobo, the Asus performed better, VRM temps were surprisingly low, but again, i run lower voltages, and i have a huge case with many fans.

Darn sweet AIO

Darn sweet AIO in its price range. Quiet and does it's job. My AMD system never fails to put a smile on my face just like when Lloyd redeems himself in Dumb & Dumber :) My build Spec's: Thermaltake Versa N24 Mid Tower, AMD's Ryzen 7 2700X w/Corsair H100i PRO RBG AIO, GIGABYTE AORUS Gaming 7 WIFI/BT mobo (awesome for OC & Disco light Bling), GIGABYTE AORUS RGB Memory 3200MHz DDR4 16GB (running at 3333MHz), GIGABYTE AORUS Xtreme GTX 1080 Ti Waterforce, EVGA Supernova 850 G1+, Pair of Mushkin SSD's in RAID 0, Intel 6000p M.2 NVME-PCIeX4 512Gb SSD (Boot), 2Tb Micron 1100 SSD, 2Tb Seagate Firecuda, 5Tb Seagate Slim USB 3.0 Ext HDD, Roccat SOVA & Kone XTD (Gaming KB/Mouse). CPU running as high as 4.37GHz Cinebench score 1804 with most Bios settings still on Auto and not manually overclocked. Set Win 10 Power/Performance to "High". And turn off "Cool & Quiet" in the bios, turn On XMP, turn On XFR and set it to Turbo or Extreme. Leave the rest to the CPU Engineers at AMD. Temps never higher than 67C running BF1, Metro Last Light Redux (Ultra), Tomb Raider (Ultra) or Skyrim SE modded with 300+ 4K mods on a 40" 4K-UHD screen (72-80+ FPS) DOOM, Far Cry 5 etc. FYI the GTX 1080 Ti Waterforce GPU also doesn't go above 60-62C while gaming.

Does a very good job at cooling down my i7 8700k

Does a very good job at cooling down my i7 8700k. I am getting frame rate boosts because of the lower temperatures and boost clock. Setup is not too difficult as long as you follow the instructions. Really nice fans and lighting! Also very quiet and good software to control everything.

Significant upgrade from H100i v2

I recently upgraded my system from i5 370k to 9700k. I reused my old H100i v2 but noticed temperatures were a bit high. Running overclocked at 5.0ghz on PRIME 95 I was topping out 92+ C on several cores after a few short minutes. It's not great for my overclock and not great for my chip life. I decided to upgrade and I am definitely happy that I did. First off, the size of the H115i pro is much bigger than the H100i v2. Radiator size is a significant contributor to cooling performance. Not only is it longer ( 280mm versus 240mm) and slightly wider, the radiator is much THICKER as well. Radiator thickness is an important aspect of cooling, sometimes more so than overall length and width. Radiator thickness adds much more cooling surface as it multiplies the extended length and width. Furthermore, the pump included in the H115i Pro seems more capable. There is a lot more noise coming from the pump than the H100i v2, but I assume this is because the pump is more capable. Speaking of noise, the noise from the H115i Pro is SIGNIFICANTLY better than the previous incarnations. The newer "Pro" versions use Corsairs ML or magnetic levitation fans. This means that there is a no contact surface between the spinning surfaces. The previous versions of all Corsair AIOs were all normal sleeve bearing fans that were very noisy depending on the fan orientation. I previously purchased the H110i (the previous version of the H115i) which used the aforementioned sleeve bearing fans and if the fans were upside down or on its side, the fans were incredibly noisy. I returned it because of this fact. All previous versions of the Corsair AIOs had an annoying habit of spinning up full speed on system startup before the software kicked in and dampened the fans down. The new ML fans spin at a maximum speed of 1200 rpm and at this speed they are almost inaudible to me, the only thing I can hear is a slight humming. At lower settings (performance, balanced, and quiet) they are whisper quiet. The H115i Pro uses 2x 140mm fans versus 2x 120mm on the H100i v2. The larger fans move more air at much lower RPMs and are quieter. Overall, the cooling capabilities of the H115i pro is much better than my h100i v2. With 30 min PRIME 95 benchmark, my H100i v2 had 92, 92, 90, and 93C on four cores cores. With the new H115i, only one core reached 90C after 30 min even after burn in. The radiator temperature stayed flatter for far longer than previously. I am definitely happy with my upgrade and would not hesitate recommending this to others. If this review was helpful for you, please give me a helpful vote. Thanks! :)

Really nice cooler

I traded my H100i got this 360mm H150i pro and it works amazing so far. I ditched the fans it came with because they dont push that much air. They are really quiet tho, but I'd rather have a cooler system for a better overclock. Im seeing a 20-25c drop in temps with the H150i with Vardar F4 120er fans. I used the same fans on the H100i for reference. Really worth it for an I7 8700k if you're overclocking. My chip would thermal throttle with the H100i almost instantly at anything over 4.7. Now im sitting at 5.1ghz and in the high 70's mid 80's while benching. In games its at 40 or so.

Corsair needs some hearing aids, but otherwise this is the best CPU cooler I've ever owned.

IMPORTANT NOTE: You need to install CORSAIR LINK and have the USB adapter installed on the cooler to manage the cooling profiles. The first cooler I got was filled with air, the pump was loud as hell because of all the bubbles going through the motor. Shaking the cooler while it was running and trying to let it settle did nothing to help. I got an exchange and the new one is much better. The pump DOES make a whirring sound, so if you're looking for absolute silence and have sensitive hearing, you may hear the pump at times. The maglev fans are insane. They make almost no noise and the zeroRPM feature is great. Now how about the actual cooling performance? I had a Noctua NH-U14S and the Corsair 1151i PRO gets 10C cooler at idle, and an entire 20C cooler at max load. Reference numbers for those that care: NOCTUA: 40C (idle), 75C (max load). CORSAIR H115i PRO: 30C (idle), 55C (max load).

Powerful cooler, low noise

One month into a new build, the Corsair Hydro H115i 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).

Software seems to no longer burn up cpu cycles

I'm running Core Temp and displaying my highest core temp. It's at 30C in a room at 68-70F. It hits around 38C max when running Farcry 5. I have an Intel Core I7 8700K cpu. There is only one complaint that I have, and it seems they have fixed it: the Corsair software was burning down 10% of my cpu power, and yes, that is a huge amount to monitor a mouse, 2 ram sticks with static color, and a cpu cooler that does lighting effects. I was extremely angry about this on purchase given the price. A few updates later and it is barely registering, so something has changed. It still logs as much cpu time as my browser which is running Netflix and two instances, but it no longer bogs down the computer like it used to. 2018-12-16 The cooler is still running without issue. The software has gotten better. Coming out of sleep mode has made me restart the software a lot of times, but it has been pretty solid other than that. The sleep mode issue may have even been fixed recently, I haven't had it since an update a few awakenings ago. Core Temp has all my temps at 31-35, 35 being the one doing something at the moment. Cores idle at 31 or less.
