Samsung 45W charger related

[SAN00SH]

Hey,

I have a question regarding the 45W charger that I bought it off from Amazon from a third party seller. 

It makes quiet loud buzzing or whining noise, like I can hear it from 3m away when I charge my phone while it's in super fast charging then once it's in normal charging, It makes less noise or won't hear it at all. 

Is it normal in this case?

Its a genuine charger by the way, I had verified that with samsung support when I bought it .

So I wanna know if I'm good to go with it or does it have some defects in it?

Its been in 2 months of use by now but that noise kind of bothers me. If it's safe then I'm alright with it.
