No data today due to a configuration issue (I moved case around slightly to change video cards and affected the seating of waterblock). I DID test out performance vs. flow rate over a range of MHz and it looks like the flow rate does drop off but not nearly as extreme as you are modeling it Les. More like 1.24 L/min at -5C coolant and 1.17 at -9C coolant (the extremes of temp I ran). Hopefully some numbers tomorrow that:
1) Reproduce some of the earlier datasets with flow rates
2) test for a given CPU wattage as a function of flow (0.3-1L/min or so)
