Fan options, where should the high airflow go?

[fire_munki]

About to get another 120mm fan for my system.
This one has a bigger air flow than the single 120mm that came with my case I should think since the case was only 30 odd quid.
The question is do I have the fan that moves the most air as the exaust fan or as the intake at the bottom?

the bottom location is always intake - exhaust is always in the upper part of the case where the warm air climbs up to.

Most research done on positive VS negative pressure shows better results with a positive pressure design (more intake than exhaust). If you live in a dusty enviornment, then that seals the deal...just use a good dust filter on the intake ;)

If you live in a very low dust enviornment, you could try negative pressure (more exhaust than intake), and compare results.
