Well the cooler air will cool the hardware faster. Part of the problem is
that air is not a good conductor of heat. I.E. I am working on a
supercooler project to cool my PC to -120^ C. I have to dunk it in a
liquid to cool it fast enough because the air just does not conduct the
heat fast enough.
I am still not sure what you are trying to do, but I think you are going
to need to look at lower temps, not just more air flow.
