If you took a loop with a CPU block, a radiator, and other stuff, it would have a pressure drop curve of y= AX^3 + BX^2 + CX + D (well, D=0). If you doubled the components in serial, you would have a pressure drop curve of y= 2AX^3 + 2BX^2 + 2CX + 2D. Basically, you'd double the resistance....

But if you took those same components and split the (doubled up) serial loop into two parallel loops....the overall restriction is much lower than even AX^3 + BX^2 + CX + D (how much so depends on the Y split and all associated with that).

But because the restriction drop is so large from going from the doubled-up serial loop to the parallel loop, flowrate through the pump increases. But overall gains in flow are not necessarily imminent. Going in parallel will only increase the flowrate outside of the parallel'd region (by drastically reducing the restriction the parallel'd components create)....as for what happens within the parallel'd components when using a Y-split, the verdict is still out (there should be some cases where it's still beneficial, but not on the scale of what the T3 does).

The reason why the T3 succeeds at doing this is because while another pumptop would require you to add components (and therefore restriction) in order to go to parallel, the T3 is a native parallel design that requires you to add components (and therefore restriction) to go to serial.

EDIT: BoxGods' PEC explanation is the true way to look at it
I don't agree. OK, maybe a more accurate way to say it, but your very first statement WAY back in this thread is the easiest way to understand it. The difference is WHERE the split (for want of a better term) happens. In the Typhoon III it happens in the pump itself.
