TPU noticed that cooling firm Arctic Cooling accidentally leaked a bunch of processor model numbers of Intel's upcoming Haswell-based LGA1150 processors. The list below contains model numbers of nine Core i7, seventeen Core i5, five Core i3, and two Pentium series models.
The list of LGA1150 processor models appears to have been leaked in the data-sheets of one of its coolers, in the section that lists compatible processors. LGA1150 appears to have the same exact cooler mount-hole spacing as LGA1155 and LGA1156 sockets, and as such upgrading CPU cooler shouldn't be on your agenda.
