If you can get a hand on a thermal camera, you might want to observe
that laptop with it.(looking for a hotspot)

Also, have you put the laptop on a wooden table ?

Have you tried leaving it 1 cm above the table (with only two linear
supports underneath, one per side ) ?

The ambient sensors might be on the bottom side, and on a wooden table,
it can rise.

If the exhaust is cool enough, what about the intake ? are they opened
enough ?

Can you run that laptop while opened to see the fan ?
