Hi @zoomie
Normally, the motherboard manufacturer includes the mounting brackets in the box of the motherboard. Or you get the mounting brackets with the cooling solution you buy.
That said, there are some manufacturers that sell mounting bracket kits for the TR4 socket. For example the Corsair Hydro Series H100i TR4 Mounting Bracket Kit.
Here is another one: STRX4/TR4 Mounting Kit by "be quiet!"
Note, instead of "mounts" I used "mounting", "bracket", and "mounting bracket" in my search.
Hope the above helps!
I hope the above help you!
