c-attack Posted July 17, 2019 Share Posted July 17, 2019 From a fluid pressure stand point, 1 pump should do it. However, there may be some clear temperature advantage for the CPU not to be in the same coolant stream as a pair of 300W GPUs. I’m not sure if a dual system is what you had in mind, but something to consider if you don’t have a lot of cpu temp headroom. Link to comment Share on other sites More sharing options...
DevBiker Posted July 17, 2019 Share Posted July 17, 2019 I have an XR5 280mm, XR7 480mm, 2 GPUs and a Threadripper ... 1 pump handles it fine. I did do a custom curve for it as the default curve didn't seem to have enough oomph to keep the GPU spinners spinning (though the liquid was flowing).

Corsair Employee Corsair GregX Posted July 18, 2019 Corsair Employee Share Posted July 18, 2019 1 XD5 unit will be more than sufficient for your system. 2x radiator + 3 water blocks. From our Custom Cooling FAQ Q: How many water blocks and radiators can one Pump/Reservoir Combo support? A: This unit delivers a head pressure of 3.9 meters, powerful enough to provide adequate flow through a custom cooling loop of at least four water blocks and three radiators.
