Depends on your system water blocks and how restrictive the loop is now, rads are pretty low restriction but they will add a bit. I would probably recommend another pump in series. My long loop only just manages to turn the flow meter in the res if i turn off 1 of the D5s. The system doesnt overheat or anything, but its a lot of load to put on one pump. My system actually runs 4-5c cooler if I turn off 1 pump but I dont trust it on one. When i finish the MM rebuild i will be running the D5s at a lower speed to slow down the loop to give the water more time to cool in the rads and reduce heat dump from the pumps.
