Is there any advantage to setting the fan on a projector to a higher speed than normal in order to lengthen the life of the bulb.

For example, if I set the fan to a "high altitude" mode in order to get more airflow, will a cooler bulb last longer?

Is this worthwhile to pursue or is it only a neglible effect on bulb life?

That's what I'm doing on my RS1, but only because where I sit I can't hear a difference.
