Annoying High Pitched Sound On My PS5 Slim

Hi,

I had a ps5 slim yesterday and upon setting it up it has this high pitched noise when in game but not in home page or media.

I've researched and people have referred to it as a hovering UFO sound and my slim sounds the same but not as loud as others but it is annoying.

Ive noticed if I press down on the circular metal fan shroud the noise mostly disappears.

Is there a temporary or DIY fix for this without replacing the fan.

I'm not sure what fan I have in the slim but above the QR code it had the letters MB.

Thanks in advance.
