Yes, Maziere (iirc)
Do you want to use one? Unless it's in a drag car that you can rebuild after the pump dies, no - their reliability in a rotary's harsh environment has not been proven.

I have foudn it very reliable, and I love being able to circulate coolant after the car turns off.

An Electrical Fan, with a Temp Switch will not provide Cooling, In terms of heat circulation. It will simply cool the Radiator the fan Is mounted on.
*EDIT* Unless you are talking about an Electric Water Pump.

Nope
As the engine coolant heatsoaks, the thermostat will open, allowing the coolant to flow through the radiator, as it would were the car running (simple convection). If you've got a well-placed temp switch (i.e. upper pax side of the rad, or the filler neck, or the upper rad hose), it will activate the fan, cooling the heatsoaked coolant that's now flowing. This will accelerate the convection, cooling the engine even more.
So you see? Electric water pumps are more about parasitic drag and getting that last 1/10th than post-shutdown cooling.
