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.

    This takes up so much less space than my Coolermaster Hyper 212! It looks great and cools my CPU so efficiently! Absolutely love it!

    I was very excited to purchase this item, it was well made and easy to install mounting brackets for your chipset, sadly the hoses were not long enough to reach my CPU. I will have to return this item.

    It's a pretty good cooler, but since I use the fan as intake fans on the front of my PC the fans have to face inward. So the RGB lighting does not look how it does in the picture.

    Quality product as usual from Corsair. Instructions too vague and do not cover different setup options or recommended installation options

    gets worse perfomance than my noctua aircooler. would not get this because you also run the risk of the pump dying on you and needing a aircooler anyway. does it look good? yes does that justify the cost? NO. my 3800x runs 4c hotter than my noctua and thats with the pump and fans on max....this is not a good buy.
