All block exhibited roughly the same temperature decrease going from the 1048 to the 1250, at least that is to say that the temperature decrease was so small that it didn't register for many instances given the 0.5C resolution of the CPU thermal diode.

Pressure? Flow? They are linked. Each block provides a particular back-pressure against a pump, and the flow rate is proportional to that back-pressure.

It may be interesting to note that the Concept (my micro-channel block) gives just 24mm^2 of orifice area for the water to squeeze through at its tightest point, and the Cyclone 4 gives 124mm^2 of channel area at its tightest point, yet both give the same flow rates (ie. have the same back-pressure). The Cyclone 4 causes the water to take 16 right angled turns while the concept has the water taking just 2. Meaning you can get away with outrageous restrictions to boost water velocity (ie. less than a 1/4" ID tube) so long as you don't make it take too many turns aferwards.
