I have an Asus X501A which runs on Windows 8. The fan is at the left hand side of the laptop. About 50 minutes ago, my laptop fan started to make very loud and weird noise - I can't really describe the noise it's making, but it's never made this noise before. It kinda sounds like a hissing noise. Every 10 minutes or so, the noise seems to get even louder and louder. It's never made this sound before.
What's causing this, guys?
