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.

    The waterblock's USB didn't have a connector in it. The cable wouldn't hold in. I ordered the 110i to replace it and it's worked great. So I think I just got a lemon, it happens.

    For some reason this cooler disconnect when the RGB is set to rainbow cycle and cpu is under load. Check out Corsairs forums. You can always change it to another RGB mode and it works fine.

      Sorry to hear,

      But the review should reflect the product itself and not what "people" with bad habits are doing to the product itself before purchase. Please bring the problem up to a BB employee or give their Corporate number a call.

      If you have anything else we can help with, please reach out: support.corsair.com

    Works well, however, the package came with a fan that had a broken light. Fan works to keep the cpu cool though.
