Dual loop compared to 2 pumps in series versus 2 pumps in parallel
Dual loop compared to 2 pumps in series versus 2 pumps in parallel
you can observe it directly how this operates. i have completed all the settings that were discussed here. my best final setup, that functioned well, is what i refer to as a complete parallel loop—every component and radiator are paired together. however, as rubix has emphasized several times, the actual loop remains a serial arrangement from components to radiators.
Yes, but a single loop remains overall, functioning as a series. Splits could be used to supply the parallel parts of the loop, though these splits eventually reconnect into a unified serial section. A parallel split would lower restriction, potentially speeding up certain sections if pumps are positioned after the split instead of before. However, this means feeding two 1/2"ID pumps with a single 1/2"ID tube, effectively halving your flow capacity. This remains a serial segment of the loop, which will naturally be more restrictive. It seems that while such setups aren't widely available commercially, most companies provide serial pump options. I’m leaning toward a series configuration if I go dual pump, but I’d appreciate any insights from someone who supports parallel operation.
you can observe the process directly since I have completed all the settings being discussed here. here are the relevant links: my final setup, which performed best, is a complete parallel loop—components and radiators are paired together. However, as rubix has emphasized, the actual loop remains serial from components to radiators. i plan to examine this thoroughly. There’s a lot of information there, so it will take some time to go through it. Thanks for the effort and the resources you provided, Toolmaker.
I only bring this up since we frequently focus on whether a loop is serial or parallel, but in reality, a perfect parallel loop doesn't exist because it remains a serial setup at some level. You're still limited by the overall flow and constraints of the circuit, which define the lowest common denominator.
I only mention this because we frequently become overly focused on whether a loop is serial or parallel, but in reality, a perfect parallel loop doesn’t exist. At some stage, it remains a serial setup, constrained by the overall flow and limitations of that part. Rubix - that’s accurate. I believe the GPU/CPU and radiator section should all run in series to maintain proper flow through the blocks. (I’m still curious about a parallel CPU/GPU loop) I’d like to determine the pump arrangement. Maybe removing one pump, as Ryan suggested, would help clarify things. Toolmaker’s data is useful, but I haven’t fully processed it yet.
Ryan here - I'm going to follow your advice since your reasoning makes sense. Also, I wasn't satisfied with the dual pump/res mock-up; it looked too messy. I changed the design so a single pump/res can be mounted, then disassembled the case for powder coating. I ended up blasting and coating all the tiny components last night (that Corsair paint is really hard to blast through).
Thanks to everyone for your feedback and insights.
Thanks Ryan - I'm going to follow your advice because your reasoning makes sense. Also, the dual pump/res mock-up didn't meet my expectations; it was too messy. I redesigned it so a single pump/res can be mounted, then disassembled the case for powder coating. I ended up blasting and coating all the small parts last night (that Corsair paint is really hard to blast through). Thanks to everyone for your feedback and insights.
Ryan6 thanks Ryan for the advice, noting the logic is solid. They mention the dual pump/res mock-up was too messy and decided to redesign with a single pump/res mounting, then removed the case for powder coating. They spent last night blasting and coating all small parts, especially since the corsair paint proved difficult to blast through. They ask for updates and request photos once completed.
