Question

Why is my computer fans making weird noises?

Answer 1

If you notice the computer fan running constantly and making an abnormal or loud noise, this might indicate that the computer is not running as efficiently as possible, and/or clogged air vents. It is important to keep dust from accumulating in your computer and ensure adequate ventilation to help reduce heat.

Answer 2

Answer:

The biggest culprit for excess noise in computers Computer internal devices all generate "heat."  Most computers manufacturer add temperature controller fans on important internal devise or locations.  These will spin faster when "hot" temperatures are detected.  With the fans, there are usually "ventilation holes" needed to push this hot "air" out.  Unfortunately, these holes let in dust and "other debris' into the fans, thus making them "spin" harder and faster. This is normal. You might want to take your computer to your school's office and ask them about your. computer. I think I have a solution below but I am not sure it will work.

Check to make sure that your computer is set to use all of your speakers. Navigate to the Control Panel, and double-click Sounds And Audio Devices. If you change this setting, click Apply, OK, and then OK again to exit the Sounds And Audio Devices Properties dialog box.

Hope this answer helped you have a good day.  :)
