My recommendation would to have at least 3 fans total (technically no fans are needed for the PC to work, just cools components). One in the front, one in the back, and one on the top or side of the case. And the best way to have the fans in the case would be to have the front fan blowing in and the back fan blowing out (or the other way around if you want to.) The main thing you should worry about with fans though is if its really cooling anything. If not, you should look into either more fans or another type of cooling system.
