Are you running a K series chip? If you are, are you going to be overclocking? What are you running for a case? Is that case running the stock fans or have you swapped the fans for others?
In general, liquid or air is only sort of relevant. Size/make of the fans that you're running matters, as does load/task, and how much air flow your case is developing. How you set up your fans matters as well. Putting together a quiet build is a holistic endeavor.
