Haven't much time to think on this, but the thought did occur to me.

It's been proven pretty much time and again that sticking water pumps in series is better than sticking them in parallel, when pushing against any form of back-pressure.

I was wondering if the same applied to axial fans?

An axial fan will push maybe 1/4 of its rated flow through a radiator. Rather than sticking two fans in parallel has anyone crunched through the math yet to find whether or not that in series would be better than in parallel?

I'd do it myself but I'm feeling lazy today and just thought I'd ask if it had been discussed before?
