In summertime when outside temp cross 30 Celsius my ventilation system works almost on maximum to maintain 27 Celsius inside my box.
Do you have hot summers also?
If yes cut holes and direct airflow and you have no worries :)
For this summer I upgraded my with importing air from room cooled by AC.
Before I had computer fan and conduct pipe filled with dry ice for cold air supply

Those hoods are so nice!
How much dry ice did you use per day?
I was buying weekly one or two kg and next week on refill sometimes it would be some traces of ice and sometimes would be totally dry. I think that was connected with humidity inside box.
