Why do you have pump speed (and flow rate) tied to CPU temps?
yeah late necro post, never saw reply.. still ironing out bugs in this loop still though. CPU temps thing was a typo I think. Turns out I was using 10mm female couplings and a male fitting on one side was slightly over 5mm threads so even tight it wasn't sealing 100%. It is better now with longer couplings, but not perfect. I'm losing up to 0.2-0.4mbar/min @ 200mbar, however fluid level in res isn't rising like before, so I'm hoping the res topseal just needs to be wetted and re-torqued.
