To answer the question the rads in the bottom compartment are fairly isolated from the upper chamber and you are probably better off having both move air in the same direction rather than drawing on the warm internal air...

hmm.. perhaps you are right but it would be top positive pressure heavy using 4x 120mm and 2x 92mm and with 5x 120mm in the lower compartment so I was hoping for some pressure push to get the slightly warm air down there.

The main thing I was concered about with your idea is feeding hot exhaust air into the second rad, are you saying this is not a concern?

I have both my rads moving air in the one direction in my TJ07 and there is no noticeable affect on performance - I have tried the air moving both ways as well and temps didnt change between them. Plus the main benefit to using the external air rather than the internal is that you are using fresh air for the first rad rather than air that has passed over every other component in your case to feed both rads...

I went with the PA rad sandwich with both sets of fans blowing in the same direction and your right its very good

3x 120mm intake - 2x 120mm exhaust.
