I have an M4 MacBook Pro. It gets hot. The fan kicks in, and it gets noisy. I can't say whether it is T14 noisy since I never heard one. As for the cool and fanless MacBook Air, my understanding is that Apple is quite aggressive with thermal throttling. That's perfectly acceptable, even desirable, under some workloads. Under other workloads, it is not.
