What customers say
This water block earns high praise for its exceptional thermal performance, delivering significant temperature reductions that support stable overclocks on powerful GPUs. Its aesthetic appeal is a major highlight; the clear flow path combined with vibrant RGB lighting creates a stunning visual centerpiece for custom builds. Users recognize the premium, durable build quality derived from nickel plated copper. The primary drawbacks noted are the premium price point, positioning it for serious enthusiasts, and a meticulous installation process that demands careful attention to detail. Despite the complexity, those who complete the setup are rewarded with top tier cooling and unmatched visual flair.
Know before you buy
This block is specifically engineered for NVIDIA GeForce RTX 3090, 3080 Ti, and 3080 cards that follow the 'Reference' PCB design. Before purchasing, verify that your specific card model matches the reference layout, as custom PCB designs from manufacturers will not fit.
Yes, it provides total conversion cooling. The block features a full-cover design that makes direct contact with the GPU core, memory modules, and VRMs to ensure comprehensive thermal management across the entire card.
The block features a high-performance copper base plate for efficient heat transfer and a durable, fully transparent acrylic top that allows you to see the coolant flow through your system.
The integrated RGB lighting is compatible with Corsair iCUE software when connected to a compatible Corsair lighting controller. This allows you to customize lighting effects and synchronize them with the rest of your Hydro X Series components.
Installing a GPU water block requires disassembling your graphics card, which will void its original manufacturer warranty. While the process is straightforward for those familiar with custom loops, it requires careful handling and patience to ensure a proper seal and thermal pad placement.
