String: if you're talking dual-loop they are independent so as long as your temps are fine, the flow rates can be different. Also fine if the loops share a res. My pumps are serial (dual top) and I don't have a problem running them at slightly different speeds (3222 and 3567 rpm currently). Given that the idea is to tolerate the failure of one, it should be fine but efficiency may be lost if too different I suspect.
It's a single loop. The reservoir, a pump and a 560mm radiator are in the garage where it's nice and cool. Inside the case (which is in my office) there's a pump, reservoir, CPU block, GPU block, 120mm Rad & 240mm Rad.
The PC connects to the "external" loop via quick disconnects. This means the PC can run independently of the external loop if required (moving case to another room or for maintenance etc..). However, when the entire loop is connected then the PC runs with no requirement for radiator fans to spin because the 560mm radiator in the garage does all the work - fluid is a steady 21C when system is gaming and running 100% load.
This is why it would be best to have the case pump @ 50% speed and the external pump at 100% speed. I'm just not sure if this would cause any issue with wear etc..
