You should change the case while looking for a CPU for the processor. I would also vote for a 280mm~360mm AIO instead of a beefy air cooler.
As for your cooler's purchase, please pass on your location, your budget for a cooler's purchase and your preferred site for purchase to understand what you have access to.
