Well, one difference between light rays and air flow is that the path
of the former is reversible, the one of the latter not. We have discussed
this already with engineering and when I remember correctly they always
told us: When the fan sucks the air out, it is much more possible to
direct the flow (by choosing inlet openings) to areas inside the case
that need cooling (processor, expansion cards,...), than it would be
possible with a fan blowing into the case (please don't ask ME for
details, I'm only a physicist... :-). I always said something like "aha".
Perhaps it really is this way, and you only could make it really
working by having two or more fans, and that would be too expensive.
But now I'm finally speculating.
