yep.. but doesn't the voodoo 5 have 2 gpus? then you'd need two... just check beforehand on the card to make sure that the hsf fits properly.. you might have to file the hsf in places to make it fit over caps or other smds. also, make sure the fan cables are long enough to get to fan headers if they're 3 pin. to attach it, i'm not sure if the v5 has little mounting holes, but if not, then i'd use good thermal epoxy, like artic silver epoxy. try this online store for that.
