There's an actual link to the vid I made showing it:
Evaporative Cooling Tower - YouTube
It was something I made because I was bored.
The final iteration was different but worked great once I changed a few things like the cooling fan for instance - Popped in a single 240CFM Delta 120mm and it was awesome!
loud but awesome.
Makes no difference.
If you want something like this you go dual loops, not split loops.
Can actually lead to the more flow restricted segment not getting enough cooling in split.
That's possible if your pump can't move enough coolant by volume, has to have it in a sufficent amount to work properly but as long as you have enough flow it will work.
I'd done dual loops, split loops and other things too such as a bleeder line for my RAM sticks regulated by a ball valve. I adjust the flow to my sticks by using the valve to do this with, opened more for more flow and opened less for less flow.
I simply connect these in series too and have a return line to the res from them.
Makes no difference.

Having a set of rad in series can possibly (I stress possibly here) lead to less efficient cooling because in that case one rad will be warmer than the other all the time BUT, as long as the total amount of cooling you get is enough it's not a problem since that's something that cools down the water/coolant
in stages.
The way my current benching setup is done I even have a separate PSU just for the cooling system itself so I can pre-cool things before I ever turn on the system itself and it's also handy for leak testing before power is even applied to the system.
Unplug the system PSU, run the coolant system PSU and that way you can check for leaks with no risk of shorting things out because of a leak.
Fix the leak, confirm it's fixed and just go from there.
