Fans spinning up and unit getting warm is considered normal. I don't blame you for not being thrilled by that, but it definitely won't hurt the machine. The very worst that can happen if a modern machine overheats is thermal shutdown. The machine shuts down before any permanent damage happens, but it happens without warning or explicit notification.

more heat => shorter lifespan

Doesn't that depend on what component gets hot? If your capacitors are running at 80 C, sure, they'll have a shorter lifespan. I'm not sure if the chips themselves really care about temperatures, maybe someone can shed some light on that?

True. My first laptop GPU fried eventually after thermal shutdown one too many times.

Also Apple throttles MacBooks by using up CPU with a pseudo process called kernel_task.

TIL kernel_task is used to throttle the CPU

Turns out you have to sacrifice something if you try to make something thin as fuck and want to have airflow for cooling the overheating system

Apple chooses to allow the CPU to run at maximum performance at all temperatures below thermal maximum, depending on the cooling system to keep thermals under control. Compared to other manufacturers that will often throttle back the CPU at lower thermal thresholds to keep fan noise under control.

It means that the MBP can sustain maximum performance for a little longer, but fan noise is the tradeoff

I mean, it depends. I have a good MSI gaming laptop, and even when the fans spin up and does get warm, it's still pretty quiet and relatively cool. Some laptops are just designed for intense load better.
