MacBook pro M3pro making a weird sound

I have encountered this problem on my Mac pro recently, when I am doing demanding tasks, like running a game or rendering websites while also doing some stuff and especially if it is charging, I get this weird sound. Is it a serious thing? or is there an immediate action I should do?

the sound is like a "WIING" for a second, then becomes silent for a second or two and then does the same again again with a more or less similar frequency.

Thanks for responding in advance:)
