Os dissipadores de calor LGA115x são compatíveis.
Da fonte 3:
Noctua's info sheet for their new NH-D15S cooler, stating it's compatible with LGA 1151 (Skylake), and the installation manual, which shows using the same design of rigid, nonadjustable backplate with fixed posts as for the current 1150/5/6, with no special instructions for 1151, so the mobo holes and socket height must match. I'd been assuming the mount would be unchanged for Skylake, but it's nice to see for sure.
