Does anyone have any clue as to how to investigate (and hopefully fix)
the issue?

Your laptop is probably clogged with dust. You need to take it apart and
clean it. I need to clean almost all my machines every year or two.

Hi,

Thank you for your answer.

Although I cannot rule this possibility out with 100% certainty, I
find it unlikely that the problem would appear all of a sudden. And it
would not explain the inaccurate fan speed reported by the sensors,
either.

It's quite common that it happens all of a sudden.

Either you notice all of a sudden, or it crosses the threshold from
not-a-problem into overheating-problem all of a sudden.

The inaccuracies are quite common too, I can usually see them even in
the BIOS of pristine machines.

Sadly, I don't have the surgical skills required for taking apart and
back together this kind of laptops.

Just get a compressed air can (make sure it's for electronics,
otherwise it might have incompatible solvents), make sure your laptop
is turned off, and blow some air through the cooler vent. Make sure to
hold the can correctly (read the instructions) to avoid propellent to
go out as well. That should move dust around enough to make things
better. And if it does make things better, then you've got
confirmation that dust is to blame.
