Stacking Radiators.... good idea?

[alphakry]

So here is my plan

I currently run a Apex H20 kit w/ 1/2" barbs, cooling the CPU and GPU.
It uses a dual-120mm radiator that came with the kit

Just for a project, i want to add a 2nd loop in my system - of smaller 1/4" tubing - to cool the chipset, mosfets and maybe even the harddrives...

My question is... in replacement of the radbox that comes with the H20 kit - is it possible to stack a single radiator?
This radiator would serve not only as the cooling radiator for the 2nd loop, but also as a spacer for the dual-rad that the larger loop uses...

Here's an example:
(don't mind the crazy cables coming from a 2nd PSU ... it was for a test)

Does this sound like an idea that would work?

it would just blow hot air into the next one behind it. I doubt you would see any improvement.

I think it would work because you are only planing on cooling the lower heat output components with the 2nd loop.
But I would use a Rad with a loose fin set up to allow more air to flow.

ya. i could understand how potentially, the air from the first loop would be blown into the 2nd - possibly increasing temps. But I don't suspect it would be that much of a difference...
