Razer Balde 15 Rattling noise

Hi Razer Comunity,

Few weeks ago I got a Razer Blade 15 Advanced (i7-9750H, RTX 2070MQ)

It does a quite loud rattling noise around the right side of the laptop. Is not constant, it comes and goes every often but it is loud and different than the normal fan noise. I tested it next to my flat mate's one (same model) and definetely her laptop doesn't do that noise. It's not triggered when I'm using graphic power so I reckon is CPU related?

Please can someone let me know what I have to do? If I live in London what Razer's support chanel do I have to use?

Thanks!
Ricard
