It depends on you socket position on motherboard!Can the bottom cover below the CPU cooler (05 in the manual's parts list) be attached when the C14S is installed?
Found a reference to this not being possible, but I think it was from before the production version was finalized.
Examples:
GIGABYTE X570 I AORUS Pro WIFI = Noctua C14s will only fit with cover removed
MSI MPG B550I Gaming Edge WIFI = Noctua C14s will only fit with cover removed
ASRock B550M-ITX/ac = Noctua C14s should fit with cover attached
ASUS ROG Strix X570-I Gaming = Noctua C14s should fit with cover attached
