The Daring Fireball review of the MBP had this to say about the fan ... "The two machines are equivalently fast in a sprint, but the MacBook Pro will win a distance race. But Apple doesn’t call it a “fan”. They call it an “active cooling system”. That sounds like a marketing euphemism, but it’s not fair to call this a “fan”. It is something else altogether, and nothing at all like the cooling systems in any previous Mac laptop. I’ve never once heard it in an entire week. Never. Not once. Not a whisper. I presume it has engaged at times when I’ve taxed the system. Again, the Cinebench multi-core CPU benchmark taxes every available CPU core for 10 minutes. But if the active cooling system has kicked in, I never heard it. I’ve never felt any air moving out of the vents, either. This is nothing at all like the fans on Intel-based MacBooks, which, if you’re not familiar, you can definitely hear, to say the least." https://daringfireball.net/2020/11/the_m1_macs https://daringfireball.net/2020/11/the_m1_macs
