Macbook Air making loud noise
My MacBook Air is new and has started making a very loud noise--it almost sounds like a frog. It's nonstop and repeats approx. every 6-7 seconds while the laptop is on, so I guess it's the fan. The laptop is not hot to the touch or overheating. I've tried rebooting, updating, and everything else I can think of to fix it. Has anyone experienced this before? What is the issue, and how do I fix it?
