For who are curious about the noise of Mac studio, I am attaching the recording file. I simply recorded it an iPhone voice memo. It was recorded directly above the unit (near the Apple logo), not in front of the exhaust
It's a bit boosted, but it sounds similar enough in my work environment that's about two feet away from unit
The noise issues I've experienced so far in Mac studios are different from fan volume. As you can see from the attached file, it has a high pitch resonance. This may not be a problem for everyone, but it is certainly quite annoying for some
