>it doesn't make any noise

You can hear the fan at full load, especially on the M4 Pro. I really wish Apple went with a larger case and fan for that chip, which would allow quieter cooling.

Also, many units are affected by idle (power supply) buzzing: https://discussions.apple.com/thread/255853533?sortBy=rank

The Mac Mini is quieter than a typical PC, but it's not literally silent like, say, a smartphone.

That might be a recent phenomenon caused by the inevitable heat of the CPU getting closer and closer to its limit? Like explained in this video: https://youtu.be/AOlXmv9EiPo

My Mac Mini M2 never does any noise, even when I run FFMpeg the fans don’t spike. It just gets slightly warmer. Still, unless I’m doing these high CPU bound activities, every time I touch it it’s cold as if it was turned off, which is very different than my previous Intel one that was always either warm or super hot.
