This is a data science build in the Dark Base Pro 901 with the Apex Distro Plate. Currently have a 360, a 240, and 2 140 radiators in the plan. With CPU and GPU at 1050 watts, I'm considering adding an external radiator or at least the fittings for one in the initial build. I've a few questions about the best way to do that. Should the external radiator be connected to one of the standard APEX in/out pairs, or should one of the pump outs be used? If using a pump out is preferred, then what should be used as the return? Also, should I consider adding another pump for the external loop? Thanks!
