Airtop3 is emitting noise

[quangkevin]

There's a hissing and ticking noise emitting from my week-old airtop3. It's much louder than my laptop which has fan running. Is it normal?

This could be coil whine coming from either the CPU or GPU electrical circuits.
We have documented an application note with methods to reduce these audible noises:

As I'm interested in Airtop3 to replace my old TNN-500 AF as my main workstation, I'm quite curious about this thread and about a noise Airtop3 emits. Do hacks mentioned by Tamir solve completely the hissing/ticking noise or not?
Thanks!
