In the past, I have seen people arge that the opposite is true, and that bulb life was shortened by running the fan and that the fan was present to allow rapid cooling when bulb replacement was required.
I have no reason to doubt you, as I don't really have experience with this.

Kino is correct in every thing he said. Let the bulb cool with the fan blowing until it is room temperature. Do not leave any hand or finger oils on the bulbs since they cause hot spot and then the bulb blows out.
Fortunately you can't touch the glass part of the bulb when its in my projector anyway, all you can touch is the coated top. Which, it just occurred to me, is probably the reason its there.
Coated or uncoated, don't touch any part of the glass envelope. I always use a clean cloth or a clean leather glove when handling these types of lamps.
