So i just changed my Fans from DC to PWM in the Bios.
After booting i heard a strange sound every 10 seconds or so. I thought it has to do with the PWM setting ,so i went back to DC.



And still i get this weird whirring sound every 10 seconds.



What happened? I can't remember hearing that sound before and im at the old settings now.



Pls help.
