The Cooler Master LGA1700 Upgrade Kit is a kit designed to enable compatibility between Cooler Master CPU coolers and motherboards using the LGA1700 socket.

The LGA1700 socket is primarily used for 12th generation Intel Core processors (Alder Lake) and represents a change in the mounting of CPU coolers compared to earlier sockets such as LGA1200.

The upgrade kit typically includes components such as new brackets, screws and all necessary equipment that allows you to install your existing Cooler Master cooler on a motherboard with an LGA1700 socket.

This is especially useful if you have an older Cooler Master CPU cooler that you'd like to continue using with a newer motherboard that supports LGA1700, as it saves you having to buy a whole new cooler.

However, the exact contents and compatibility of the upgrade kit may vary depending on the specific cooler model and motherboard layout, so it is important to confirm compatibility and check the contents of the kit before purchase. In addition, it is a good idea to follow Cooler Master's installation instructions closely to ensure a safe and efficient installation of the cooler.
