I right now cooling my i7-4930k with a Hyper 212 Evo but was consider replacing the cooler with an H100i. Core temps reach mid-60's during Prime 95 's small FFT test using my Hyper 212 Evo at stock clocks. I have a CM 690 II Adv. case but my cable management is not very neat. Do I need good cable management inside my case for an H100i or any of these dual fan liquid CPU coolers? Also is it harder to install the H100i than it is the Hyper 212 Evo? Also what are the chances of getting a leak for the H100i or the liquid inside it drying out?
