It doesn't sound healthy...
I don't remember what it sounded like before this sound started - But that just proves that I haven't had this sound since I bought it.


It's like a constant rattle (quiet) like something's loose... And then there's a quieter hummmmmmmm from the fan..

Maybe Apple's support docs have something on it?
Or you've got it too?

... take it to a apple store? maybe something somehow got inside there and the fans are just batting it around... which can't be healthy.

I had a slight flaw with my battery cover and upon taking my MBP to an Apple Store, I received a new machine and they transferred my data for free. A fan problem might be a bit harder to show/explain, but I'm sure they'll have a look at it.

Thanks both :)
