Warming up a 2019-era (Intel) MacBook Pro was never my problem. Quite the opposite. Those machines ran notoriously hot. The later macOS releases, combined with company-mandated crapware, made it worse. Doing an ordinary build or starting a videoconferencing session was enough to cause the fans to run. On a warm day the fans couldn’t shed enough heat and so the system would go into thermal throttling. The OS would occupy a core with a 100% kernel_task that didn’t do any work but which would serve to prevent actual work from being scheduled onto that core. When four or five out of the six cores were occupied by kernel_task, I knew I was in for a bag of hurt (to steal a phrase from Steve Jobs). Responsiveness went completely to hell. The machine became effectively unusable.

After a while my normal procedure was to run with the thing sitting on top of an ice pack. That would let me run a 60-90 minute video conference without troubles.

The only redeeming feature of these machines is that they could emulate old x86 hardware at speed. That allowed me to run old apps on old OSes without having to keep old hardware running.

My Intel MBP would noticeably raise the whole room's temperature, while the fans ran so loud. We had some corporate security software that would occasionally go haywire and lock up 100% of a core until you rebooted. If you got that at the same time as a video call it would become too physically painful to touch any part of the metal body with bare skin.

Maybe the same type. Each time I call the LLM api the fan starts to work and make big noise. The temperature in the room is going up noticeably for 1-2 degrees.
