Question Gpu fans makes vibration noise on startup

[Alectrona]

I have a gigabyte 4060ti whenever the fans startup it vibrates for a quick second not a big deal because I have a 55% fan curve set is this normal???

I have a 3060ti that does the same thing, not really a big concern if it is only on startup. I believe it is semi common as others have talked about it in this thread https://www.reddit.com/r/sffpc/comments/polfwm/evga_rtx3070_sc_making_strange_fan_vibration_on/
