Im going to start building my own radiator and was looking on advice on how to run the copper tubing.
Below is one design (sorry about the crude drawing i just used paint
). The radiator is split in half, the inlet side has a chamber where the first fitting will be, the water enters the chamber then through the tube on the left side and enters a chamber at the bottom which is connected to the other side and fluid goes up the other side and goes out. I put the tubing in a v shape so that each piece of tubing gets air flow across it.

My other disign is just a single piece of tubing routed through the fins bent 180deg, then back through the fins and so on.
Im just trying to figure out which design will give me the best cooling. I've found diy guides for building your own radiator and havent found anything about the best way to run the the tubing. I may also be thinking way to much into it but any info would be greatly appreciated. I also know that i can just buy a radiator but i want to take a crack at building my own since i enjoy tinkering with stuff.
