I dont know of many cases that can support a Quad rad at the top, and far less that can support a triple at the bottom. Is this a Corsair 900D or a Caselabs/Mountain Mods case?
You may want to draw things to scale as well, currently that "360"mm rad comapred to the 480 looks like a 120mm rad.
We kind of need a lot more info before we can judge the viability of the loop.
