Ok so after a few hours playing around with wires I am finally done!
I have managed to fit the H100i in the top of the CM Storm Scout 2 (non advanced if that makes any difference)
I have both fans installed inside the case, directly under where the mesh was and where the H100i is. Sadly I can only fit ONE 25mm fan on the top of the H100i so I have a half and half push pull effect.
I have not modded the case AT ALL bar removing the mesh and bending it into shape to fit over the fan and rad with my hands.
For anyone looking at the clearance between the H100i and the case handle on the CM Storm Scout 2 here it is!
Now you could get a very low profile fan 12 - 15mm and it should fit with no problem or modding under the handle of the case.
And here is the full set up I have on the top of the case
Oh yeah, just in case anyone is wondering there is still quite a strong force being produced from the single fan under the H100i
I also tested it without the top fan and there was still enough air flow to lift a small piece of paper and keep it hovering until it lost balance and yes I did spend around a half hour playing with this
I hope this post helps someone that is looking into doing the same thing myself and a few others on this forum have done
