High-pitched whistling sound when connected

[funkyfoenky]

Hi!

I recently modded my switch v2 by myself and everything went well.
Except that for a few days, the console is emitting a high-pitched whistling sound when it's connected via USB and data is being transferred via DBI.
When data is not being transferred the sound is almost not hearable but sometimes present.
There is no sound when the console is not plugged in.
Do you have any idea of what could cause that and if it is a real security issue?

Thank you in advance.

You happen to notice it prior to mod, like when USB-C charging? Can you share quality close up photos of your work?

I didn't notice anything before recently even after modding I didn't noticed that for approximately 1 week. I will try to take pictures but It is probably covered by thermal paste so I will have to remove everything.
I might have found what is the cause... I shared my switch to a friend awaiting his switch to be repaired (charging port and M92 replacement due to shortage). I think he used the same charger as for his switch on mine. Do you think it could be the issue?

So a third party charger, I'm guessing? I wonder why some people are willing to risk harming their expensive console with a strange charging peripheral, when they could have used the recommended charger that came with their console.

I wonder also why a person who has its console with a faulty charging port used the same charger to charge a healthy console... And after the other console has been repaired he just told me that he charged it with the same charger...
