well I don't think you can tie it into your Corsair Hydro Series H110i and why I think you would need a real loop for cpu and gpu use ??
me here I never needed a cpu water cooler but I would like to try the evga 980 ti hybrid
may contact corsairs support on cutting the lines on that unit and if the pump is strong enough to push the cards block on top of the rest ??
if your card is not getting over like 80c at long term full load call it good ??
this is the latest on the 970 from evga
