Yeah, I should avoid commenting on stuff I'm not intimately familiar with... I'm not aircooling my components as you know... but I have my stacker 830 configured such that the four fans on the door/rads are all blowing into the case as well as a fan on the lower front.... no exhaust fans at all and there is a considerable breeze of warm air emanating out of the blow-hole.

I'm sure you are right in that you are better off with more fans than less when air cooling.
