Know before you buy
The XC9 is compatible with a wide range of modern sockets, including Intel LGA 2066, 1200, and 115X, as well as AMD Socket AM4 and sTRX4.
Yes, the XC9 features pre-applied thermal paste, which simplifies the installation process and ensures optimal thermal conductivity right out of the box.
The block uses standard G1/4'' BSPP threads, making it compatible with the vast majority of custom cooling fittings available on the market.
The XC9 uses a standard ARGB connector, allowing it to be controlled by most motherboard software. However, using a Corsair iCUE-compatible controller will provide the most seamless integration and advanced lighting effects.
The transparent chamber allows you to visually monitor your coolant flow and check for potential air bubbles or debris buildup, which helps you maintain the health of your custom loop.
The cold plate is constructed from nickel-plated copper. This combination provides excellent thermal conductivity while the nickel plating helps prevent corrosion and oxidation over time.
