TJ09 airflow?

[citizen__erased]

I've just ordered 2xPapst 41 CFM fans to put in the top two empty fan bays on my TJ09. Currently the side intake is sucking air in and the fan at the back is blowing air out. When i add the two new fans, i'll have three blowing air out and one sucking air in. This doesn't sound like a good plan. Should i turn the rear fan the other way round? Any ideas?

The grid around the mobo tray will let in air so it'll be fine.

I read about some people doing that in the case thread but I have had it both ways and found no change in my temps. I have them as exhaust, which is what I believe what they are meant by design to be, at least with air cooling. Water-well thats a nice place for a 120.2
