Hey JettonX im just speaking from personal experience i'm currently using a corsair h100i and i think it's great , you can utilise the software to adjust fan speeds , configure profiles and colours on the cpu block it self , if your interested in using the software . In terms of peformance this is just an example of an overclocking profile that iv'e used with the h100i
3570k 4.2 ghz 1.1 v or 1.070 i get mid 30's on average idle and 61 or there abouts on load with default fan speeds , still messing around here and there just's just an example and remember tom's overclocking video's are there aswell as people on the forum and the " silicone lottery " ticket has to be accounted for .
Hope this helps .
