if you have that much at idle (if it is radiators input/output difference) it usually means really REEALLY low water flow.Zitat
For example i'm working with a Delta of 5C at idle and more than double that under any significant load. Time and future tests on the new system with like 3x the rad space will tell, and ill make the necessary config changes to the controller.
It sounds to me as if you want to design your cooling for maximum noise level, my cooling is designed for minimum noise level, hence 4x 420 radiators with very slow fans and a pump setting that is not audible.
I also dislike high water temperatures.

smaller rad surface area shouldn't impact differential that much. In fact with less surface area, you should have smaller differentials because the rads dissipate less energy per pass. So it really looks like a low flow situation.
Usually radiators in parallel is very inefficient, people tend to do blocks in parallel instead to avoid feeding one block's heat in the other (even if it makes little difference). But regardless, with parallel loops you usually have to run higher pump speeds by default to make sure the bits you run in parallel get enough flow. If not, there's often one run that gets most of the flow and the others pretty much linger.
Maybe you can try to "reverse" your PWM control, like, running the pump fairly high, and modulate fan speed instead of runnings fans high and having variable pump speed. Purely because of the heavy use of parallel connections, i think it may yield better results.
But yea, finish the loop first then tweak controls :p
Correct which is why im using a dual pump in series so that I can combine the head from both. If I up the flow rate parallel rads will be more efficient. And the pressure drop from the QDC’s and parallel rads will be manageable with the increased pump pressure. Only reason I’m doing 8 is purely so I can exchange all hardware without draining the loop through the fold out MB tray.
This is interesting. It kind of reminds me of the Intercooler Thermal Regulator. That did turn out to have some significant issues, but those aside, it was another example of complex sensor data processing that can be done in Aquasuite.
I would just give it an actual drain port on the bottom and a "drain port" on the top where you can hook in a LeakSHIELD as needed. With a loop like yours where everything is vertical and plumbed in parallel, a LeakSHIELD can really easily do a vacuum-assisted fill on the first shot without even needing to cycle the pump. Without those QDCs, a single D5 could easily hit 200lph in a loop like yours and that would be well beyond the point of diminishing returns with regard to coolant flow.
You have like 600W max sustained load even with a 4090 in there. This whole loop could be run by a D5 NEXT set to a 40C target and a SPLITTY 9 for connecting the fans. Coolant flow and fan speeds (including turning off completely) would all be automatically regulated.
I suspect they are the same person.
