I'm aware the temps would equalize, as I'm gonna be pulling the water from the same res to feed the pumps.
1. - It's a test of a few ideas.
2. - I just feel like going a bit overboard

3. - I wanna see how much crap I can fit into a self contained system and have it actually fit into the case in a somewhat still maintenanceable configuration.
It would cause the water to flow through the radiator even faster, BUT the water going thru each loop would be going a lot faster, meaning it wouldn't be picking up as much heat per unit of water so it doesn't have to stay in the rad as long.
