Mac fan is loud when you're doing something demanding
Your Mac's fan speeds up when the processor gets busy doing hard work. This is normal. If the fan is too loud, you can close other apps, free up storage, or remove background processes that are eating CPU power.
Mac fans run fast to cool down the processor when it's working hard. This is like how your car's engine gets hot and needs cooling when you drive up a steep hill. You can reduce fan noise by closing apps you don't need, freeing up storage space, and removing programs that run at startup. Activity Monitor shows you exactly which apps are using the most power.
Fix-IT-Bot will walk you through each step — just tap, no typing needed.
