Is there something wrong with the m5s? I have an m4 pro and I’ve never heard the fan on it. I don’t do much with local llms, but I naturally use the web and play games (windows games at that with wine/crossover).

That seems very unusual for modern Apple Silicon. Our family has:

- M3 Pro MacBook Pro 36GB

- M2 Pro MacBook Pro 16GB

- Mac Studio M4 Max 48GB

and I have not heard the fans on any of them with normal use. The only time I've ever heard automatic fans was when I was using a local 12B model on the M3 MacBook Pro, and when running 70B models on the Studio.

You should consider checking Activity Monitor and making sure that the usual suspects are not causing issues with sustained high CPU. And you can use an app like [Stats](https://mac-stats.com) if you want to see that info while actively using the computer.

As someone who just upgraded a month ago from the last Intel MBP to a new base M5 MBP, I think your laptop might have a problem. I'm definitely not experiencing any of what you describe when doing normal tasks.

This is not normal. You have a broken Mac. Make an appointment.
