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.

    I have this on my Intel i9 and it’s been running great. The software to change the RGB on the fans are easy to use and customize. It looks great lighting up my computer and showcasing what’s inside.

    Out of the box, it was kinda confusing. There two different brackets to fit an Intel processor or an AMD processor. It’s surprisingly easy to install and the RGB makes it look really nice. 8/8 two thumbs up

    It keeps my i7-9700k in the mid 70's with an all core 5.1 GhZ boost. It also makes pretty lights. Do be aware that there are several more cables for the RGB that you have to now manage.

    Excellent AIO, very good build quality. Once you download corsair icue its very easy to adjust fan speeds and change the rgb effects. Easy to install. Only complaint it that its a little pricey at $150

    Great cooler. Using with an overclocked i7-10700K. CPU temps have been great. Lights look great with asus sync case fans and led ram. Relatively easy to install. So far no complaints.

    Super quiet and efficient cooler. Very happy with the much lower temps as it seems my previous cooler master unit never really did work. Color works on the fans but not the processor cooler. Updated iCue software and still no luck.

    Works great at keeping my 3900x nice and cool. Extremely easy to setup and install. Software is a little resource hungry, but works very well in managing the fans and cooler pump.

    I changed out my Corsair cooler (H150i) at 360mm for this 280 mm setup. I am actually seeing better cooling performance despite the smaller and more attractive setup; who does like RGBs!?

    Very easy to set up. Fits perfectly in my corsair crystal 680x case. Keeps my ryzen 9 3900XT cpu cool at idle and under load. Don't think I've seen temps past 60C often.

    You get what you pay for with this cooling system. Only drawback is that sometimes iCUE can be a pain to work with, but is necessary if you want interesting RGB patterns. Keeps my CPU cool even when overclocked.

    So I purchased this puppy as a replacement for my recently purchased Corsair H110i Platinum AIO Liquid CPU Cooler. Let’s just say that this is what I was looking for as my 9700k was idling in the mid 40s. Upgraded to this bad boy and now I’m idling in the mid to upper 30s. I just needed something more than what the H110 was able to provide and the H115i Platinum (which uses a 280 vs a 240 radiator) is just what I needed! I would recommend up to a 9900K but the 9700K is the sweet spot for this one.

    This aio keeps my i9 9900k (not oc’d) at around 55-60C at max load. Much better than my previous fan cooler from Enermax. Certainly expensive though
