Aside from the Air Cooler Fan/s, I'd put 2 front intakes, 1 rear exhaust and 1 top exhaust.

Here's a nice test video using different fan quantities/configurations in a typical PC case with air cooling and their corresponding temperature readings: https://www.youtube.com/watch?v=8OmkmluAYAQ

0 Case Fans (Air Cooler Only) = CPU: 71C | GPU: 92C
1 Rear (Exhaust) Fan = CPU: 64C | GPU: 85C
1 Top (Exhaust) Fan = CPU: 65C | GPU: 83C
1 Front (Intake) Fan = CPU: 67C | GPU: 80C
1 Front (Intake) Fan + 1 Rear (Exhaust) Fan = CPU: 60C | GPU: 79C
2 Front (Intake) Fans + 1 Rear (Exhaust) Fan = CPU: 58C | GPU: 77C
2 Front (Intake) Fans + 1 Rear (Exhaust) Fan + 1 Top (Exhaust) Fan = CPU: 55C | GPU: 76C
2 Front (Intake) Fans + 1 Rear (Exhaust) Fan + 2 Top (Exhaust) Fans = CPU: 55C | GPU: 76C <-- Adding 1 top fan = no effect as above
