not really. It's REAL easy to make your own PCI Fan card though if you have a spare PCI Card or something that could just be busted laying around.
I forget exactly where I read it, but it's not like you need instructions to do it. I just took a fan from an AMD64 stock heatsink, drilled holes through some PC board that just had a couple extra USB's that are to fit in the back of the computer and screwed the fan on with that.
You can see the fan below my graphics card in this:
I haven't been able to OC the graphics care more than normal. And no temp monitoring so I really don't know if it's even making a difference. I suppose it'll cool your graphics card down a little but I wouldn't expect much
