Dual Serial or Dual Parallel Bridge PC Watercooling Diagram
Parallel flow bridge is less restrictive than serial flow. It's often used with single or weaker pressure PC water pumps. For strong water pump loop configurations, there is little or no difference between parallel or serial. Parallel lines reduce coolant pressure, so results will depend upon the water block designs, water pump and tubing layout. In a dual serial system, it's possible you may see 2 - 3 degree temperature difference between the GPU water blocks. Your liquid will only flow as fast as the restriction allows, so it really boils down to pump, block designs, and tubing layout. You can always experiment too, record your temps in the two different configurations and compare the difference.
