1994 Honda Accord Cooling Fans Question

I haven’t been able to find this answer online or within this Forum, so any and all answers will be welcome. To start off, I had a radiator cooling fan demolish itself (the blades were not connected to the motor anymore). This is the larger fan on the passenger side of the radiator. I just put a new one in and it was actually very easy, and took less than an hour not really racing through it. After I put the new one in and everything was connected with the electrical and all other fasteners, I proceeded to try to test the fan. (my own curiosity to make sure it works)

I idled the car and the smaller AC condenser fan would kick on, but not the larger fan. The when AC is on, the condenser fan operates regardless of the vehicle being on or not (proper operation).

The true question is, does each fan have a different temperature at which they are supposed to get signal from a fan switch and operate? Hypothetically, lets say the radiator cooling fan needs a higher temp. (some cars have an “above boiling” switch and a “below boiling” switch for different fans) Can I safely unplug the AC condenser fan to increase the temperature of the cooling system to check operation that way? What are the best ways to check the radiator fan performance generated by engine heat? It simply could mean that the engine never got hot enough to need the second fan. (It is currently 65F and 10mph wind Here in Minnesota)

Important note: This car never has overheated, never overheats and was properly bled with a spill free funnel after a block heater was added last winter, and bled again (found no air or low coolant) a month ago.

If anyone can do a detailed write-up of how the entire fan(s) operations are supposed to work that would be FANTASTIC.
