Thunderbolt Power Supply Crackling

Hello,

I’ve noticed a very slight crackling sound when using my MacBook Pro 16” M4 Max powered only via Thunderbolt. The crackling is very faint and only lasts a few seconds (or even microseconds) when performing certain operations (for example, clicking a button on a web page).

The crackling sound disappears when the Mac is connected via MagSafe for power, with Thunderbolt used only for display.

Any recommendations?

Thanks
