Radiator stacking with AP-15s

[OVerLoRDI]

So in my watercooling adventures I have acquired quite a few extra parts over the last year. I was thinking of making use of my extra Swiftech MCR320 for cooling my CPU loop instead of the current single 120mm rad I have. However, my only option for mounting it is to stack it with my other 3x120mm radiator.

Behold:


Sorry about the size. That is however my basic plan.

My thoughts are:
Each radiator is a separate loop, the smaller swiftech is for the CPU, and the thicker EK is for my GPUs. The GPUs will generate significantly more heat, thus it will be on top to avoid the issue of the GPUs heating the CPU. The CPU radiator will be on the bottom, so the heat from the CPU will be transferred to the GPUs slightly. So my conclusion will be, I'll see load temps of the GPUs increase slightly, which won't be an issue. 45C vs 50C? Not a big deal. CPU temps peak at about 65 on my single 120mm rad, with a 3x120mm rad, I'd imagine I'd see significantly decreased temps on the CPU. Thus I think it might be a worth while option.

The only concern I have is whether or not the GT AP-15s will have enough static pressure to push/pull through both rads effectively. What do you guys think?

put the ap15s inbetween the read maybe? That's what I'd try first.

that is what I had in mind.

I think I'm going to just go ahead and test it this weekend, unless someone chimes in with news that it is a terrible idea.

no ideal but it will work.. if you have spare room i would stick more fans on the first radiator

That would improve temps on my GPU loop only. My CPU and GPU are on separate loops.

since they're going to be double stacked. the bottom fans will add more pressure and help the fans in the middle

seems stacking reduces the performance of the rads when compared to mounting them separately, such as on on top and one on bottom.
