AMD Athlon 3000G stock fan makes an high pitched tone when operated in PWM mode

I've recently completed my first build and everything went pretty smoothly.

I've turned on the pc and from time 0 an high pitched noise is coming from the CPU fan (stock Athlon 3000G - serial written on the fan: dkm 7d52a-a6-gp) (https://streamable.com/1grie)

I've tried to fiddle around in the BIOS (I've yet to install an OS) and I noticed that if I change the operation mode to DC the noise is gone at any fan speed. When setting the PWM mode again this high pitched noise kicks back at any speed.

What can I do? Should I give up and use the CPU fan in DC mode or is it a thousand times better to use the fan in PWM mode?
