When I launch my PC it is very loud for several seconds. It is Noctua NH-D15 and it connected to CPU_FAN and CPU_OPT 4 pin connectors on Gigabyte X570 Aorus Elite motherboard. Both fans work in PWM control mode. BIOS version is F11.
Is this normal or can it be fixed some way?

This lasts since I built this PC and now I'm tired of this sound a little. Also, it can wake up my wife.
my Asrock X570 Phantom Gaming X does the same thing.
