The heatsink mounting on Intel's new LGA1200 platform (code name Comet Lake S, Z490 chipset) is identical to all LGA115x sockets (LGA1150, LGA1151, LGA1155, LGA1156).
Not 100% sure I heard correctly, but aren't the 1200 chips slightly bigger now?
Good to know, cheers.The chips maybe but the socket mounting is the same so older coolers will correctly mount. The IHS is basically the same and the older blocks will work fine.
