So I got my Macbook Pro 13 inch a couple of months ago and recently, I've been using it quite often. One day while I was turning it off, a strange loud fan grinding noise came out of no where and it really scared me. It stopped once I turned it off. I turned it back on to see if it was gonna happen again, and it did. I immediately shut it back down. I did some research on what it was on my HP and apparently it is an internal fan to prevent my laptop from overheating. So with this information, I avoided any use of my laptop for about 4 to 5 days. Today, I turned it on. I'm currently on it right now. And it's still going on. My parents are considering taking it to the Apple Store and getting a completely new one. I seen on YouTube that people use heat control pads, or something. And that there's widgets to download. I don't want to have to go spend extra money, or take up extra memory just for something that should not give me problems in the first place. Does anyone have any advice (e.g. not leaving it on sleep mode while in a carrying case) or information that would help me. It's greatly appreciated.
