Customers are saying

Customers love the Hydro Series H115i RGB Platinum's excellent cooling performance and vibrant RGB lighting. Many appreciate its quiet operation and ease of installation, finding the setup process straightforward. While some found the size of the radiator to be a limiting factor and others felt the price was high, the positive feedback on cooling and aesthetics outweighs these concerns for most users.

    Everything works as advertised. The radiator dimensions could maybe have allowed for another fan to screw in next to it, but no such luck, however, the size is probably for the best to help move heat from the CPU, so I'm not really complaining. Also would have liked the tubes to be a little longer, but that's mostly because I have a very large case, and wouldn't have minded using this as recommended in the manual (as intake) instead of exhaust.

    i kept going back and forth between this and the 380 mm. Unfortunately, the newer version of the 380 AIO was not available. Set it up the fans as a pull method. This AIO still does not disappoint. Temps have yet to go over 30 degrees Celsius. The ML RGB isn't as bright but when you're wanting to have performance fans on your AIO. ML Fans are the way to go :)

    I needed a cooling system for my CyberPower PC. The air cooling that came with it was not doing the job. I purchased the unit from BestBuy and they installed it. It did not work the first time as it was connected wrong. After having it checked over again, it worked great. Lowered my operating temp from 70 degrees C to 40 Degrees C.

    Being a first time builder i chose this as a means of cooling for later overclocking if i chose to, being said the stock settings on this cooler do more than enough for keeping your system cool and looking great. Used this cooler for nearly 2 months with the pre applied thermal paste with great numbers even when cranking the power on my machine.

    This was a great cooler while it lasted. I installed this cooler in November of 2019. It kept my Ryzen 3700x at about 32c idle and 50c under load. After 11 months, I started my computer one day and the pump was making a high pitch whining sound and the CPU started over heating. Pump seems to have gone bad. It is a shame because I really liked this cooler. I will say that for the first six months I ran this cooler with the tubes up. I later learned, even though the instructions present it this way, is wrong because you get cavitation and this can cause the pumps to go bad sooner. Looks like I didn't catch it soon enough. If you get this cooler be sure to install with the tubes down or at the top of your case. Just submitted my RMA so I am hoping Corsair is true to their 5year promise. We will see.

      Hi Luke,

      We'll take care of your RMA, is there any reason as to why you would say you're hoping we're true to our promise? Is there anything you saw that makes you think otherwise? Please mention it to the agent taking care of your ticket so we can look into it!

    Paired with my Intel i7 8700K it works well, even to well thinking about it. The max my processor can get up to is 105C while it never goes above 60C and stayed around 50C while playing online games. You might think the RGB is over the top and is not worth it but its a way to impress your friends when they come over for drinks.

    Corsair's lighting modules coordinate as part of an entire system for larger cases. I swapped out an older All in One cooler for this one with no problem. Corsair's Discord support provides a horde of experienced users to advise on the most complicated lighting integrations.

    Good choice as a CPU cooler for someone looking to water cool without going all out. Temperatures don’t go about 80° on stress tests now which is good compared to the 98° I was getting before. I use my computer for video editing and this keeps the CPU cool when rendering out the videos.

    Upgraded from Hyper Evo 212 and have had a consistent 15° temperature drop. Turning the fans on max has yielded a 20-25° temperature reduction. The only reason I dont rate 5 stars is due to the inability to fine tune fan speeds. Running a i7 7700k OC to 4.8Ghz on all cores. In game temp is 50-55 peak with front mount rad and 3 exhaust fans.

    Depending on how big or small your case is it can either be difficult or easy to install this. This was my first time installing a cooler and it required me taking apart nearly my entire PC. Temps dropped significantly after installation though.
