28 gallon HQI JBJ nano

Hey! Hopefully someone has an answer for me. I bought a used setup and when cleaning the fans and replacing bulbs before use, I noticed the fans all force air to the inside of the reflector. Is this correct? Wouldn't it be more efficient to run 2 in on one side and 2 out on the other to get cross flow across the bulb?

Any advice would be great here. I'm about to screw it all together and don't want to take it apart a day later if my concerns are correct.

Thanks in advance
