Aurora R8, buzz noise

Hi everyone I have an Alienware Aurora r8 and it about a month old. I haven't really played games on it but when I do I hear a buzzing sound coming from the pc. I only hear/ notice it when I play a game like Fortnite but when I play a game like State of Decay 2 it gets louder and noticeable. It only happens when I play a game and it stops when I'm done other than that the pc works fine. What can I do to fix it. I'm not sure where it originating from my guess it one of the fans I'm not sure. Any help would be appreciated.
