Reviving an old thread but just as I was about to retire this old system I came across a matched pair of the 10 core 2470 v2 CPUs for a bargain price so I rebuilt the system into a new case and it will live on in some capacity.Digging around my box of misc bits I found a couple of 775 HSF retaining rings and wondered if they'd fit the hole spacings in my X8DTE-F, which has a pair of 1366 CPUs. Turns out they match quite nicely, but you have to be careful the legs that touch the PCB aren't fouling any SMD resistors, etc. If necessary, trim a piece from the edge of the leg without affecting its stability or spacing. I held the rings down with some M3 screws and washers into the backplate.
After that it was a simple matter to fit the pair of Akasa AK-876 coolers, which were available cheaply as New Old Stock AM3 coolers. They clipped on as if made for it.

Unfortunately the previous cooling solution isnt going to work, I also stumbled on this as an alternative.
You can pick these rings up for next to nothing on Ali Express: https://www.aliexpress.com/item/100...o.order_list.order_list_main.5.7eba1802wQKUii
This CPU Cooler comes with them and appears to... work. https://www.aliexpress.com/item/400....order_list.order_list_main.11.7eba1802wQKUii
