Guys seem almost all MacBook Pro 16 have this issue - go to the apple forum and leave comments - more effort to make us heard.

This is exactly what I hear on my 16’’.
I’ll give some context of my situation.
I’ve had my 16’’ since november, so around 6 months. Since the beginning I always felt a little cracking sound when I boot it up, right before the Apple logo appears. It bothered me at first but didn’t pay too much attention to it and eventually accepted it. Besides that, and the regular fan noise under heavy load (the fan noise in my 16’’ has always been pretty impressive compared to my last 15’’) never really heard any coil whine, or at least, never noticed it. A couple of weeks ago i felt some weird noises, and I thought it was the fans, as if they got stuck or something, but everytime I stopped doing what I was doing to hear closely, the sound would stop; kept working and forgot about it. But today, editing, started hearing it non-stop, like with any minor change on an adjustment layer in Photoshop, opening any folder, or changing any parameter in Lightroom, I would hear it. Most of the time, to actually hear it I would have to put my head closer to the keyboard, but if I wanted to paste the adjustments from a photo to another in Lightroom, it is definitely noticeable from a normal position.
So after reading the whole thread I came up with the next conclusions:
1. There’s no way around, there’s always gonna be some level of coil whine, regardless of specs, and unless it’s unbearable, I wouldn’t return.
2. If it was there for 6 months straight and I never heard it, there’s gotta definitely be a perception factor. I doubt it just got worse out of the blue.
3. It happens in different tasks. Wether it is reading SSD, using Benchmark 4 (CPU) or GPU demanding tasks.
I’ll let you know if something changes.
If anyone notice it with similar examples as I do, let me know
