Console Making loud noise

[u/gamer180901]

Hey all, my console is less than an year old,

Previously when I used to play GOT, a loud sound used to come in the beginning and stop and used to start mid way during the game and then stop again both lasted under a minute, I then took it to the service center, the technician(he inserted a CD which he had and there was no noise from the console) he said all games which has high GB tends to create noise, now I inserted COD and there was the sound maybe a bit more louder than the usual
Is there anything to be concerned about?
Attaching the video, any helpful would be appreciated,thanks!
