This is probably a design issue where the turbulence from the fan is interacting with the cooling fins and causing a buzz or squeal type noise. The same issue with the PWM fans on the Hybrid shroud on the 1080 Ti.
I imagine if turbulence was an issue the noise would change along with fan speed, which isn't the case.
You would be surprised what kind of noise you can get. On the 1080 ti, the PITCH does not change only the timbre and volume. Most here are saying it DOES change, so I don't know what you're on about.

I doubt it. If that were the case it wouldn't be a constant sound as the fan ramps up from zero. This is 100% the fan electronics or the power delivery for them.
It isn't constant though and and PWM fan noise also changes with RPM. Not sure why folks are not making technically accurate comments. Come on, it is just a theory based on experience.
Lastly, as far as I know, all three fans are identical. So, the theory of it being a defective FAN would seem unlikely as the LOCATION is the common denominator not the type or model of fan.
