MacBookPro 16-inch has current noise, cpu turbo frequency noise?

I found that during the use of the newly purchased MacBookPro 16-inch, such as opening large software and restarting the system, noisy sounds will be heard under the keyboard. Should be the noise caused by Intel CPU Turbo? Some in the community also said that it was noise from SSD read disks. It's strange to hear this kind of sound at night when it is quiet. Is it a quality problem? Is it normal? Does everyone's MacBookPro also have this current noise? Wait for your feedback, thank you. (My MacBookPro 16-inch is i9-9880H CPU and 1T SSD)

Model - MacBook Pro 16, Intel Core i7-9750H

The coil whine appears when there is a sharp high power supply to the processor.When the turboboost is turned on, the power is jumped to 80 watts and the squeaking is heard. If you turn off the turbo boost and run the test, the power will not rise above 40 watts and the coil whine will not be heard. For the load testing was used Geekbench. For power measurement, the Intel Power Gadget was used. Turbo Boost Switcher was used fo turn on/turn off turbo boost.Below images with measurement.

With turboboost on




With coil whine - turbo boost on


Without coil whine - turbo boost is off
