As has been said, top tier air coolers are easily as good as CLCs, but we need to setup case airflow so case is flowing air in sync with air cooling components' needs. This means lower airflow at idle and low load and case progressively flowing more are as componet load increases and their cooler fans' speed increases and use more air.
What case do you have? What is the case fan setup going to be with CPU being air cooled?
You might find the basic guide to how airflow works and how to optimize case airflow in below link of interest.
