If you are talking about buying an external fan to go along with the card, anything will work (depending on the type of tower/case you have.) If you are talking about replacing the fan that is built into the card, you can attach the Zalman vf1000 fan to the card & it will work just the same. Honestly, the best thing to do, because the GeForce 7300 is a relatively cheap card, you would be better off replacing the entire card with the same or newer model.
