Having a loud fan can indicate a few different things. To help diagnose and potentially fix the issue, you should:
- Check your device’s temperature
Use an app or BIOS to confirm that your laptop’s temperature is lower than it should be. - Clean out your laptop
Consider using a compressed air can to remove any dust buildup from vents, fans and other areas. - Delete unneccesary files
Delete files that are taking up too much space and causing your device to slow down.
