Time is an important factor. The longer the coolant stays in the engine, the hotter it gets. Conversely, the longer it stays in the radiator, the cooler it gets, with the ambient temp being the limiting factor. Slowing the flow can increase cooling because the engine coolant is what causes the thermostat to open and if the water entering the engine is cooler because it has stayed in the radiator longer, then it can cool the engine better. If the system was free-flowing, the engine would almost certainly run hotter if the ambient was high. But with the thermostat and its orifice being the limiting factor that it is, slowing the flow, the temp may well drop if the system is in good shape and the flow is slowed.
Not to hijack the thread, but I think it's been pretty well covered. Now, here's an interesting question. If you halved the number of vanes on the water pump and kept the speed the same, what happens to the cooling? I've got some ideas and input, but I'd like to see what you guys think and why.
