There was an NVIDIA update recently [1] that caused problems with temperatures being properly reported. Entirely software, killed some video cards. Though entirely nvidia's fault I wouldn't say it's because they make garbage hardware in any way.
It seems increasingly these problems (including the NVIDIA one) are only cropping up on 24H2 machines which is why I've decided to stick with 23H2 until it's out of its support window. Unfortunately that's coming up pretty soon.
