Well, as both are nice and all, i was wondering which one would be a better cooling solution for the processor. And of course, i'm trying to make a theme in my system too. (Like if i go with the Kraken i'll get more of those white fans and some white sleeved cables) or if i get the H100i i'll just get black sleeve cables. Since the Cosmos II tower has three 120mm slots on the top, i could get a third fan and put it on the roof toward the end where the control panel is to help with exhaust. Where the Kraken is just two big 140mm's. I know this might sound strange, but i'm just trying to give my rig more style, preformance and looks internally.
