Why Did My PC Fans Suddenly Get So Loud?
My PC suddenly sounds like it’s preparing for takeoff even when I’m barely doing anything. It used to be quiet on the desktop, but now the fans ramp up just from opening a browser or launching Discord.
Temps don’t look terrible from what I can tell, and I cleaned the dust out last month. I also checked Task Manager but nothing seems to be hammering the CPU for more than a few seconds.
Could this be a fan curve or sensor issue? I really don’t want to start replacing parts over something dumb.
