This makes sense as the extra heat removed from the chip has to go somewhere, and with a lower flow helps it show up more.

Under what controlled conditions were such tests taken? This is total trash.
I'm sorry to be so blunt, but such statements really are total crap.
The water won't be warmer. Why? Because the CPU is pumping the same amount of heat into the water. There is no "extra heat". If the CPU has clocked at a certain speed, and runs at a certain voltage, running a certain program, it emits the same amount of heat energy.
The technical reason why the White Water cools so well is because it lower the thermal gradients from the CPU surface to the point that the heat is absorbed by the water.
It's easiest to think of it like electrical resistance. The White Water offer less thermal resistance for the heat to dissipate, therefore the "voltage drop/potential difference" (temperature difference) from input to output is less.
