Intel’s upcoming LGA1200 socket (socket H5), which should appear on new Z490 motherboards, appears to be cooler-compatible with older LGA115x socket. This means that any CPU cooler that works on LGA1156, LGA1155, LGA1150, and LGA1151 should be compatible with the new socket. Of course you are going to want to make sure the cooler has the cooling capacity for some of the higher TDP SKUs like the Core i9-10900K.
Mechanical drawings of both the LGA1151 (socket H4) and LGA1200 (socket H5) were posted to twitter. These show that the new LGA1200 socket has the same dimensions as the older socket.
A picture of the grid layout of an LGA1200 package was also leaked to the web. It shows how Intel has used the empty space on the fiberglass substrate to add in the 49 additional pins without changing the size of the contacts.
Intel will debut the LGA1200 socket with their 10th generation Core “Comet Lake” desktop processors and motherboard based on the Z490 chipset, this is expected to happen in Q2-2020.
