Three fans but no rear fan?

I recently built a new computer with some spare parts I have and the case I bought had no rear fan. I didn't have any 120mm fans but what I did use however is two exhaust fans on top and an intake in the front with 140mm fans.

I'm just wondering if this is good airflow. Should I also leave the rear part of the case where the fan should be alone or cover it to ensure hot air goes to the exhaust fans on top?
