Greg's suggestion of loose fan housing screws is probably the best one. You 
really can't rely on just listening to locate sounds like this. Stick a long 
screwdriver down on the block and then put your ear to the blunt end. Moving 
the working end around will reveal lots of sounds that you never heard before 
and let you tell better where they are actually coming from.

When I install a fan housng, I tap the holes deeper, use longer bolts and 
Loctite. As you are probably about to find out, these are really hard to get to, 
so you really don't want them coming loose.

Plus, they will do a lot of damage to the fan. I have good fans if you need one.
