M$ spent millions designing airflow in the Xbox and how it relates to the shape of the bottom of the tray and if you add a fan you'll mess the airflow up and your xbox will run hotter.
That may be true for the Xbox, but he's installing it in a PC. Plus, I put an extra fan in my box and there's been no problems. It's been running cooler. I used to set one on top of my HD when I had problems with it.
