Buzz sound when using Blender on MacBook Pro 13" M1 2020

Hi!

I recently try using Blender 3.0.1 the native version for apple silicon. This is my first time using blender.

On the third day i using blender, i just realized that a weird noise comes out of the keyboard (near the screen hinge). The buzz sound only heard when i rotating/move the object in blender using trackpad or middle button on my mouse.

It’s not loud at all but it’s definitely something you can hear if you’re in a really really quiet room. It’s like a crackling noise and some weird really soft cracks. It’s really not loud at all you have to put your ear closer to the keyboard to hear it.

I read on other thread and websites, is it the heat from the SoC pushing against the heat sink? Or coil whining?

Any idea if this is normal?

Thank you so much!
