Cooling question - airflow - design

Ok gotcha. Then my original advice of keeping the systems separated holds up. If you need multiple fans on a single radiator, know that fans in series (one front and one back) will increase the static pressure, good for moving air through a resistance (thick core, tight fins, etc) and fans in parallel will increase the volume (more cfm).
i bought one of these. the transmission cooler on the machine, which is just as large as the radiator pictured, is going to sit right behind it.

So, back to the first post, i was going to set a fan on the other side of this mess, and just have both of them run if either circuit needs to shed heat/needs cool air.

The fact it has a shroud i don't know is a plus or a gain for what i have going on, but $180 as is? I couldn't go wrong, and there reason for radiator purchase is as follows.

I chose this one because my frame is only so wide, and the roof is so far up, at the same time i'm out of center to use the fan that originally was on the water pump, the radiator/cooler(s) are/is going to be sitting too high since i'm running a small input shaft off the front of the crank to get power to a hydraulic pump. Factory fan blades are going to chop into my driveline.

So electric and up we go. Just need to battle CFM movement now. this radiator is 3.5" thick, and the trans cooler going behind it, is another 2-3 inches thick. and yes, the fins on the steel trans cooler are quite tight. I power washed 65 years of dirt and backed clay out of them, so that can't be a negative. Maybe i don't even need a fan on the trans cooler, but it's a risk i don't want to gamble.
