Just get a D5 and manipulate its flowrate under stress test until you're satisfied lol.
The higher you run your D5 the more heat it dumps into the loop. So while you do want a higher flow, you also want to dump as little heat from the pump into the loop as you can.If noise of pump doesnt bother you, the highest setting on a D5 will give best temps since heat transfer improves to small degree at radiator and larger degree at waterblocks with higher flow, which you can see with your own testing. Optimal flow to me is the highest D5 setting that I can tolerate the pump noise.

once you start adding more pumps, you can run into scenarios where heat dump from pumps will exceed temp lowering from increased flow, but with 1 pump just not going to run into that issue by increasing speed, not to mention maybe 10W difference between low speed and high speed. Skinneelabs and martin both found that 1 or 2 pumps the temp lowering effect persisted in typical cpu/gpu/rad loops, only after 3rd pump did heat dump from pump exceed diminishing returns from increased flow causing slightly increased temps.
23W of heat at 100% (D5 from EKWB) is nothing. It won't even raise waters temperature by 1C.

Probably optimal in terms of power draw + noise compared to end result.https://www.google.com/search?q=Optimal+flow+rate+for+Heatkiller+IV+pro
Hmm... I'm not seeing "1 GPM" anywhere. Maybe I'll try a different search term:
Nope, still not seeing "1 GPM anywhere...
Ok now this is interesting... It certainly looks like the performance of every single block tested scales beyond 1 GPM... I thought you said 1 GPM was optimal for every block?
Here's another interesting one. All 3 blocks (and both jet plate configurations on the quantum magnitude) scale with flow beyond 1 GPM. So how again is 1 GPM optimal?
If you know of some other testing that shows otherwise, or even better, specific flow rate vs temperature scaling for the HK IV Pro (like the OP was specifically asking about), please do share.
