I have an M4 Max MacBook Pro and it generates plenty of heat, especially when gaming, compiling, or transcoding. I think that's still far less heat than it could've generated if it weren't Apple Silicon, though.
I have an M3 Max, and since I don't do a lot of close to the metal work, I can almost always use my fan spinning as a metric for a poorly designed app.
Nice :) I upgraded from an M3 Pro about a month ago. (My $2,000 mistake is not saving up for this from the start. Apple machines can't be upgraded anymore :<)
