Cooler manufacturer Noctua revealed today (opens in new tab) that Intel’s upcoming LGA 1200 CPU socket for Comet Lake-S CPUs will be compatible with all existing LGA115x heatsinks, confirming speculation from a report last year.
For those who need catching up, LGA 1200 is an upgrade to Intel’s LGA115x socket, which the chipmaker introduced with Skylake back in 2015. True to its name, it has 49 more pins than an LGA115X socket, which should improve power delivery.
“The heatsink mounting on Intel’s new LGA 1200 (code name Comet Lake S) is identical to all LGA115x sockets (LGA 1150, LGA 1151, LGA 1155, LGA 1156,” Noctua wrote this week on its FAQ page. “Therefore, all Noctua CPU coolers that support LGA 115x also support LGA 1200 and don’t require any mounting updates.”
This is great news for builders looking to upgrade their CPUs, but perhaps not their CPU coolers.
Noctua's reveal also backs up as tweet from hardware detective @momomo_us, who posted a diagram of what appeared to be an LGA 1200 socket on Twitter. The diagram showed similar dimensions to LGA 115x, which led us to conclude that the heatsink mechanism likely hadn’t been changed. We’re glad to get official word, even if you may still need to purchase an Intel 400-series motherboard to use with Comet Lake-S.
Noctua also added that while many of its older cooler models don’t support LGA 115x or LGA 1200 sockets, customers can order a NM-i115X Upgrade-Kit (opens in new tab) to make them compatible free of charge.
Intel has yet to comment on Noctua’s statement.
