Take control of your Mac’s fans
Set fan speed by hand on any Apple Silicon Mac with a fan, watch every sensor live, and let macOS take back over the moment you quit.
Your Mac runs hot because it is trying to stay quiet
Every Mac with a fan hands its cooling to a controller in firmware. That controller reads the temperature of the chip and decides how much airflow to spend, and it is tuned so your machine stays silent in a quiet room. It will let the processor sit close to its thermal limit for a long time before it spends any noise on cooling it down.
That is the right default for most people most of the time. It is the wrong default halfway through a forty-minute export, when the machine is hot, the fans are barely turning, and macOS has quietly started reducing clock speed to protect the chip. That reduction is thermal throttling, and you feel it as a Mac that got slower for no reason you can see.

Is running your Mac’s fans at maximum safe?
Short answer: yes, within the range your hardware reports. The longer answer is about bearing life, dust, and whether the noise buys you anything.

A forty-minute export is the workload most likely to make a Mac throttle. The fix is rarely the one people reach for first.
