I've made custom case for 120mm fan - airflow is bad. But you can increase height in source and try it with 2 120mm fans.https://www.thingiverse.com/thing:3718245
Addition. Checking 2 120mm set. Added 2nd 120mm fan in current case. Conclusion: 2 120 mm fan set will beat single 80 mm version.
Addition 2. Checking 2 80mm set. 2 80mm fans feat whole highest case, I've placed top part on the top fan and airflow is even worse that single 80mm fan.
