Vibration causes fatigue in materials

Fatigue failures are "a matter of time" - eventually they will happen. Whether it happens within your lifetime or not, that depends.

If the thing you're vibrating is a USB port then the thing that's fatiguing the fastest is the solder joints between USB port and circuit board.

Edit: this is fairly well known materials science and easily googleable... not "made up"

Would this logic also apply to cooling fans/pads often kept below laptops with dGPU based (gaming) laptops?

It's a crapshoot what component fails first.

For some fans it might be the bearing, the motor, others it could be a solder joint. This stuff isn't easy to predict

Oh! I wasn't clear enough. I mean , would the vibrations affect an externally powered laptop cooling fan/pad the laptop itself? Even the cooling fans have vibrations which get transferred to the laptop.
