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.

    Easy to install with multiple fan options. Icue software makes everything simple. My only complaint was due to the wide array of applications it can be used for, the initial alignment was more than i expected. Typically heatsinks drop straight in, this one has some space to wiggle for different applications. Its not a deal breaker but adds unnecessary time to the install. After overclocking temps wont even past 30 degrees. The build quality is very durable.

    Nice quality AIO. Keeps my i9-9900k at about 35-46C during a gaming gaming in a warm room. And naturally, even cooler in a colder room. Looks very nice in a build. The fins on the radiator are bound to create noise if you have fans pushing a lot of air (the noise starts to become noticeable at about 1500-1600rpm+).
