I have a 2x2 feet 200 watt square box fan. I measured its power
consumption with a Kill-a-watt watt meter, and it measured at about
205 watts on the highest setting. It perceptibly blows a lot of air
and creates quite a wind.

Keeping in mind that I have not yet even received the heater... Would
a 200 watt fan move enough air to cool down a 9.6 kW coil?

thanks

200 watts would be enough, if the blade design is right for the
application. The volume and velocity of air required depends on
several variables:

desired hot surface temperature (coil)
hot surface area
back pressure

My 100,000 BTU/hr (29.3 KW) unit heater has about a 200 watt fan on
it. It also has a lot of heat exchanger area.
