You mean with a side-duct? Yes, is that supposed to be some
kind of rare thing?
I"ve modded cases and added side-duct as well as fan(s)
too... so what? It's laughable that with 3 cases you feel
you have a comprehensive understanding of the differences in
noise between different case design specifications.

Nevertheless, the side duct reduces flow through the bottom
half and drive rack. Result is either hotter running parts
or addition of a fan to offset this flow reduction, which is
not complimentary to lowering noise, unless it also means
you manually reduce the rear exhaust fan speeds.

I do know you have insufficient experience with fans based
on your statements. If only you knew a little more about
fans, you'd then know why the statements were revealing- oh
the irony of it all.
Anyway, no, less isn't more. The quietest configuration is
running fans at the lowest RPM possible before they get into
a pre-stall threshold where there is a pulsing sound as each
coil energization causes a sudden current increase and
torque. So it's not a matter of less # of fans, it's a
matter how many fans are needed with each at this lowest
noise RPM. It can mean only one fan, in a fairly low end,
low heat system. It always means more than one on any
well-endowed system, often 3 or more. However, most systems
are not so endowed, will be fine with one fairly sizeable
rear chassis fan and the one in the PSU. If you add a
side-duct to the case, you may easily need add another fan
just to counter-act this reduction in flow to other areas.
Is it a crusade? YES! I modify cases regularly, and right
this minute have one about 18" away that has been modified,
and three more behind it, and (hmm, I can't see behind those
3 at the moment!). In fact I"ve probably modified 10X more
cases than you've ever owned. I pay careful attention to
noise, and airflow, as these are the whole point of
modifications... only someone inexperienced, judges noise
based on an arbitrary idea about # of fans, not considering
the RPM or additive effects of multiple fans being lower
noise than fewer fans moving same amount of air.
I do it because doing same thing different day is boring,
and because I like to overclock too (non-critical systems)
but not at the expense of noise.
Again I suggest you rethink your whole argument, you do not
have evidence with only two particular cases. Each case,
and each fan selection choice makes a difference regardless
of which spec is used.
Even then, it's incredible that you don't see why the
side-duct is working against low noise. Which SPECIFIC area
of system cooling do you attribute to the noise reduction?
Since the front intake is not excluded in the Thermally
Advantaged spec, we can ignore it completely and focus on
this side-duct. Do you think the CPU fan will run quieter?
Can you hear your CPU fan in either system? I can't in any
of the ATX cases you claim would be louder. So with CPU fan
out of the way, what is the noise source that's going to
make regular ATX louder because it lacks the side-duct?
It's possible the PSU exhaust will be a little quieter with
a side-duct, but only if the case has too much restriction
to intake in other areas. With any case, either design, one
should avoid cases with poor intake so we can rule this out
as well, it's not a constant but varies per case.
Yet again I"ll mention it just for the heck of it (since you
seem to have totally ignored it the last couple times)-
OEMs build quiet systems without side-ducts. The vast
majority of systems do not have them. This case you have
that is ATX, not Thermally Advantaged, is almost certainly
not as quiet as a semi-standard ATX make by (for example)
Dell, HP or Gateway. This in itself is yet again evidence
that you'e basing your conclusion on the wrong variable, it
is not whether the case is "Thermally Advantaged" or not.
In summary, you would do well to start modifying cases if
you really have an interest in case layout and cooling
designs. Only after you have a case and measure temps,
THEN modify it and compare, will you begin to see the
significance of any alterations. Then get some fans, some
quiet ones since you apparently do not have quiet fans, else
you would not be reporting "noisier" in either config, you'd
be reporting "hotter". This alone shows you are comparing
individual fans and fan mounts more than cases.
