Hey guys

Im building an external rad box and i have two MCR-220 rads. As of right now im not sure how im going to plumb them. I will be running two 1/2 modded ddc pumps in series. Basically i am considering (A). Running rads in series or (B). running in parallel using a wye to split the flow into the rads, then from the rads running a hose from each to the reservoir (so two hose inlets into the res).

I know there is basically no way to know without proper testing which way would be better. I am wondering however if wye's are associated with large pressure drops? Right now im leaning towards going parallel rather than in series. While flow rate would be lower the Dt (air/water) of the water entering the second rad would be higher compared to the Dt of the cooled water entering the second rad in series. Since i will have two pumps i am assuming that the Dt component will be more important in lowering temps than the water's flow rate, since flow rate should be relatively high.

Just wondering everyone's thoughts on this and also that whole wye pressure drop question. Thanks
