I hear strange noises from my ps4

I hear weird noise from my ps4
I have record the sound Thad my ps4 pro produces in a video on YouTube is Fridgegaming (I have 2 videos 1 I is Thad I am playing rainbow and the other one is the weird ps4 pro noise

i hope you can help me I would really appreciate it

Sounds like produced by fan…

No it is not my fan because when I turn my ps4 pro on I don’t have the sound in the beginning

Because when your ps4 gets hot the fan spins faster…
