Computer fan is running loud all the time
Something is using all your CPU and making the computer work hard. Open Task Manager on Windows or Activity Monitor on Mac and look for processes using 80%+ CPU. Close unnecessary programs.
A loud fan means your computer is working hard and generating heat. This happens when a program is using all the CPU, your hard drive is full, or your computer needs cleaning. Finding and closing the CPU-heavy process fixes it.
