XFX HD-587A-ZNFC

I recently bought an XFX 5870. From the webshop it says its a HD-587A-ZNFC but I don't see this model on the XFX website (i'm looking for the fan profile BIOS update for my model). Has XFX discontinued support or might the shop have put down the wrong model number? How would I find out what model number I have?
