Pc starts making bzzing sound when playing wow classic / sod

Hello, i recently bougth a new pc and got some issues when logging into classic wow, my pc starts making this buzzing sound and i couldnt figure out whats the issue yet. When i first startet wow on this pc i also had a coil whine issue but was able to fix that with caping max foreground fps. My pc can run all modern games on the highest settings without any issues i just dont get why it wouldhave issues with running a 20 yo game.
