This article is part of the CPU socket series

LGA 1700 (Socket V) is an Intel microprocessor compatible socket for Alder Lake desktop CPUs which was released in Q4 2021.

LGA 1700 is designed as a replacement for LGA 1200 (known as Socket H5) and it has 1700 protruding pins to make contact with the pads on the processor. Compared to its predecessor, it has 500 more pins, which required a major change in socket and processor sizes; it is 7.5 mm longer. It is the first major change in Intel's LGA desktop CPU socket size since the introduction of LGA 775 in 2004, especially for consumer-grade CPU sockets. The larger size also required a change in the heatsink fastening holes configuration, making previously used cooling solutions incompatible with LGA 1700 motherboards and CPUs.[2] Noctua among other cooler companies is working on upgrade kits for existing coolers as well as new coolers for this socket.
