Need help ASAP!

I have all of my components now (I hope). Hardware has been installed and checked. Starting the cooling build tomorrow, but am not sure of how to set up airflow through my rads.

I am using a 900D. The catch is, I have installed a solid midplate. I am putting a 480mm and a 240mm in the basement. Should both rads be pulling air into the case? The only means of exhaust would be through the front of the case where the bottom 120mm intake fan USED to be. Will the competing airflow of the two rads cause any issues with heat dissipation?

Alternatively, if I set this up with the 480mm pulling air in, and the 240mm exhausting, am I really dissipating any heat via the 240mm rad, as the airflow accross it would be pre-heated by the 480mm rad?

PLEASE HELP!!

Run it through from one side to the other it will be able to get a less restrictive flow than just going out the front and exhausting via the PSU. As for pre-heating the air before entering the next rad it will be slightly less efficient than getting the coldest possible air possible from outside, similar to using a top exhaust rad where it takes partially warm air from inside the case to cool the rad, but it won't be one that is a serve dampener to the system. At most compared to the coldest air it might be a few degrees less efficient depending on the warmed air.

Thanks a ton!!!
