Noctua today announced that all of its current multi-socket desktop CPU coolers, such as the popular NH-D15, NH-U14S and NH-U12S, now also include installation hardware for the AM4 socket of AMD&r... Noctua CPU Coolers Now Include AM4 Mounting
This still works for people who have bought their coolers already. That really worked well that one time I did it, they sent me the proper mounting brackets within the week, no charge (I could have picked it up at their offices though). A good move, after all, saves Noctua themselves a lot of hustle, and they probably faded out some older socket anyway, material costs practically 0.
Uh...I bought a Noctua sometime last year and it mounted to my AM4 just fine. Am I missing something?
