As far as cooling efficiency, I think it is better to blow onto,
rather than pull away from. Pulling away can tend to produce wimpy,
un-directed, low velocity air flow. Blowing onto puts the airflow
where you want it, with more velocity and <action>. Plus, as another
poster points out, you have a way to add filters as needed.
