Thank for the reply.
The reason I'm asking the question is that I picked up two more ML120 fans for push/pull. To keep things simple I would like to run a splitter on each of the pump's fan channels so that each is powering two fans.
I've found information on all the previous models with respect to the max current of the controller and they vary from 1A to 4A. I didn't want to just assume it was 2A as the 4 fans together pull just over 1A (the two pull fans are the red RGB variant of the ML120 pro series rated at 0.299A).
I currently have the pull fans on a separate fan controller, but that is just a stop gap. I would like to run them with the push fans on the pump fan controller.
