Room ventilation recomendations

I am getting ready to convert a heated sun room to a cigar lounge. I want to put in some affordable ventilation in the ceiling. I was thinking about placing 2-3 low noie bath fans in the ceiling but figured some of you may have other recommendations. Windows and door open when warm but I am freezing here in Kansas with one window open and another with a fan. Also do the Czonkas really work.
