ASUS GL502VS - weird fan noise

Hi Tek Syndicate forum!

I have a little issue.
So I bought the ASUS GL502VS (GTX1070), overall I’m very happy with this laptop.
But while gaming, when the GPU fan ramps up, it makes this high pitched noise. Not like coil whine high pitched but very annoying noise and this is something I’ve never experienced on a laptop before.
So I was wondering does anyone experienced this on the GL502VS?? GTX1070 or GTX970M models it doesn’t matter I think, as the fans are the same on both models.
I’ve made a video where you can hear this high pitched sound. https://www.youtube.com/watch?v=5nlunPzdl_M
You hear clearly the fans blowing air but on top of that you hear the high pitched sound.

Thanks in advance all.

Cheers,

Could be the fan bearing.

Certain bearing types, especially the ones on cheap fans, can be quite noisy.

Cheap fans?? On a 2000€ worth laptop?? I really hope Asus didn't do that.
