Yeah, those bubbles probably aren't going to help temps. Is it possible to fix the pump at something like 30 or 40% PWM? Perhaps that would minimize the bubbles. I think the benefit of more flow peters out at some point, especially as the pump begins to dump more heat into the loop at higher speeds.
I see you had trouble fitting the compression fitting on the reservoir - bummer. I think Swiftech came out with a newer revision that was modified to allow enough clearance for 3/4" OD compression fittings. Perhaps they're allowing a swap out on those???
Anyway, get it all optimized and bled, play with fan orientation and setup, and then report temps again
