The SSD or the GDDR6 chips?Sounds like poor thermal dissipation design around the memory modules (bottom), which can potentially affect the long-term performance (health) of those chips. Removing those fugly sides can help reduce thermals slightly.
EDIT: Ok so it's the GDDR6 chips. But I think those (14C) could be rated to sustain higher temps than usual.
The RAM inside PS5 D9XKV seems a newer customized version
