Strange sounds / coil noise? coming from gpu, vrm or cpu on G752VY

The sound was there almost all the time, I only noticed that it's not the HDD recently when i closely analyzed the noise through the rear panel (service panel) and noticed it came from somewhere in the heatsink area.
It's like this mostly during IDLE or non intensive usage.
It sounds almost the same as a working HDD so that's why I didn't worry until now. If you want to know how it sounds, it's something like this:

or this (which states it is coil whine) https://www.youtube.com/watch?v=blyswNKEPEY
I can clearly hear it from 2 meters away from the laptop.
I'm absolutely sure it's not the HDD!
Also, the sound changes to something different and less noisy if i play games and the components are under load, i have to put my ear on the laptop to hear it.

Any ideas about this?

I've had the same issue. are you using bios 303? if so, that's my suspect. try rolling back to a previews bios and check if the issue persist. that's what i did.

That leads me to think its a fan issue, 303 change the fan profiles where as fans would drop down to 800 RPM or so before 303 after 303 minimum is 1900 RPM much better for cooling Mine is silent, above 4000 RPM I only here the air flow.

Definitely not from the fans. I've put them to a complete stop and made sure by looking through the transparent plastic that they're not spinning. I will try what theGOAT suggested, I'll come back with updates.

I've changed back and forth between 213 and 303 with no differences 😞

If you have already updated other BIOS and the strange sounds still the same, we might suggest you to bring back your NB to our service center to find the problem.

The following is the contact information:

Problem is I already disassembled it to repaste, i was getting high 90's on my CPU. So my warranty is void now. I'll just live with the annoying noise. 😞
