Not to rain on Shaun o's parade but the H60 is twice as expensive as the lower end air coolers it competes with and adds a mechanical pump to fail. The only closed loop cooling I would ever consider would be at the top end where the best coolers beat high end air by a few degrees.
Skylake hits it's overclock wall well before temps become an issue in most cases. I can't get my 6700K to 70C unless I run Prime 95 and Intel Burn Test at the same time and even then only one core breaks 70C. Using a Phanteks PH TC-14 PE and overclocked to 4.6Ghz at 1.35v. The i5 without Hyperthreading will run cooler than my i7. Even a Hyper 212 Evo is fine and it costs half of the H60 and performs similarly.
