and if money is no issue, Watercooling, Either the CM H100 or Antec Kuhler H20 920. Just to cover all basis, if you ever wanna step that way. But yes the Evo is much better, get a second fan for it and put it into Push Pull Config.
Don't use a plastic loop. Strong air fans like the Noctua D14 or Phanteks TC-14 will give you the exact same results as a closed block like the H100 will any time of the day. If you're going to do liquid cooling, go with a real radiator and custom loop or not at all. That's my two cents.
