Nice work.
So, nearly all but 2 GPU blocks are acceptable to flow 1-gallon/min. The HFV P1 seems to bee a good contender overall for both the right tuned flow for a loop and for performance. My preference is not really OCing, but WCing for a quiet computer. The flow rate of 1-1.5 gal/min is a nice sweet spot to do this. Anyone wanting to cool a mini-ITX knows this for home multi-media.
The MCP350 DDC pump tends to be a favorite for this sort of flow and matching this up with the review here offers more selections.
