Loud Fans on Macbook

My laptop is making a loud noise. Think it is the fan. Ugh.

Since laptops only have one moving part which is the fan, you are probably correct. One of two causes. 1: there is a process going crazy causing heat to build up therefore triggering the fan to come on. 2: The fan sensor might be physically broken in which case only apple would do the hardware repair. If you call AppleCare they can send a box, you ship it to them, then they ship it back. One way to eliminate whether the problem is hardware or software is to boot into “safe” mode. Turn the computer on while holding down the shift key. Once the computer boots, use it for a few minutes. If the fan is still going crazy: it’s hardware. If the fan no longer sounds loud, then it’s probably a software issue in which case, I can fix for you via a pickup/dropoff if you’d like.
