There are two BIOS available on the EVGA forums depending on the version of card you bought.
On mine, it raises the default gpu/shader clock speed to 720/1440 and unlocks the fan speed to 30% to 100% range. Free built in overclock!
Now for some linkage:

Edit:
My bad, seems to have been out a while, although it came through the EVGA twitter feed yesterday....
Edit 2:ZOMG I am dumb, it was updated to 1.1 yesterday, that added the reduction to 30% fan speed!
