I’d never advocate for sprayfoam in the exhaust. It takes seconds to do and may reach way too far into the piping making it impossible to remove. It seems mean spirited and expensive to have a car be towed. Even worse, the two component stuff can clog a already running car. Definitly BAD!

Oh, shit. Forget my other comment. Just get a SSD cooler. With this much space you may get away with a bit of added thermal mass; assuming you aren’t constantly transfering large files. For small bursts just handling the heat spikes may suffice.

The motherboard can actually act as a heatsink. A bunch of notebook manufaturers will stick thermalpads between the m.2 SSD and the motherboard to cool the SSD, at almost zero cost.

You could try a glob of thermal putty and see if that helps. Thermalpads can be a bit finnicky due to the exact sizing requirements.

I think all of the G7 Thinkpads are back with SO-DIMMs or LPCAMM2, depending on the model.

Ifixit gave them a 10/10. I hope Lenovo keeps with this trajectory.
