Okay, so, my 2016 Macbook Pro’s fan is making a weird noise, here’s the story: My keyboard and screen were dirty so I turned off my Macbook (i only turn it off when I clean it) and cleaned it. Then I turned it back on. It showed the Apple logo and a weird loading bar that said “10 minutes remaining.” I thought it was trying to update because I don’t update it often. I let it go the 10 minutes. I logged back in, watched a youtube video. I was going to like the video so I pressed the like button, and it said I was logged out. I logged back in and went about my daily business as normal. I took off my headphones while browsing Ebay and heard an unsteady noise coming from my macbook. It was the fan! The fan never turns on while i’m on safari. The fan never makes that weird sound. Help?
