Macbook pro fan makes a grinding-like noise
I was watching TV shows on Hulu, and my fan began making a noise that sounded like a grinding action.
I'm unsure if it was doing this because I was holding the laptop, possibly pushing on the fan, or if there is an actual issue with my laptop.
After shutting down the computer, the issue seemed to go away. But I'm unsure if this is temporary, or if there is a larger problem at hand.
Thanks for any help
MacBook Pro, Mac OS X (10.6.8)
