Ok so with my computer case layout and planning my routing and setup of rads and hoses would 2 MCR120s be more effective with high cfm fans than a single dual? Here's a layout of what I want to accomplish.
I already have the 2x120 rad but wanted to go with something a little bit different.
Everything I've seen suggests that rad performance within a single design tends to scale close to pretty linearly with surface area. There might be a slight edge towards multiple rads, but you're also going to increase the system's restriction, so it's probably pretty close to a wash.
That layout should work, as long as there's a supply of cool intake air for both rads to access, and you don't mind the breeze aimed forwards.
