We've heard rumors from pretty reliable sources, but Noctua just gave us our first official confirmation that Intel's next high-end desktop platform will use the LGA 2066 socket. In a press release about heatsink support for the new socket, Noctua says that most of its current coolers support "the new LGA 2066 socket of Intel's 'Basin Falls' X299 platform for Skylake-X and Kaby Lake-X CPUs out of the box," and that it will provide updated mounting hardware for older heatsinks at no additional charge.
This isn't exactly a surprise to anyone who's been keeping an eye out for rumors, but it's nice to have an official source. It's also great to see Noctua keeping up its strong post-sale support. Noctua even says the heatsink mounting mechanism on LGA 2066 is "identical" to that of LGA 2011. Going by that statement, even other companies' LGA 2011-compatible heatsinks are likely to fit LGA 2066, and the socket dimensions are likely very similar, too. If you need updated mounting hardware, just contact Noctua with your proof of purchase.
