Hi friend, glad the Hyper 212 Plus soldiered on for so many years and has served you well.
Unfortunately, the Hyper 212 Plus unlike the Hyper 212 EVO never got the updated brackets for AM4 support and thus did not support the AM5 socket, officially.
Both coolers use the same mounting accessories from what I can see on their respective product pages (linked below). If this is indeed the case for you as well, you can get the Hyper 212 EVO AM4/AM5 from our US Store, get in touch here.
Do note that these products are now legacy, so support and spares are not assured. =]
If you are considering a new purchase, we have revamped the Hyper 212 for the modern era with the Hyper 212 Halo.
Hope this helps. Cheers!
