I am looking at two different cpu coolers. I can't decide between the nzxt kraken x61 and the corsair h100i. I have the NZXT Full tower enthusiast edition and right now I am looking at closed loop liquid cooling for my CPU (intel core i7 4770k). I wanted to put the radiator at the top of the case where there is some empty space. I was wondering which was better(More efficient and quieter), and will they both fit.
