Audible noise of the Xavier NX module

We are using Xavier NX module on our sound sensitive product. Recently we find under heavy load or moderate load, the module may buzz. Such as mouse click, or window open, close, will cause it buzz. When we do much CUDA calculations, it will continue buzz :).

Anyone noticed this? What we can do on our side? Or what can Nvidia guys help us?

Thanks.

Hi, have you located the buzz source on board? It sounds like noise from super capacitors.

We are struggling to locate the point of the noise. But it’s difficult for us to do that when it’s mounted on our board. But we are lacking of fixtures to make it run without our complex carrier board. May you test it to confirm this?

Thanks.

Is it on your custom carrier board only? We don’t meet such noise on devkit. Please try to locate the point.
