How about a simpler Volvo two-relay controller with low speed for AC (existing aux fan trigger) and high speed over a coolant setpoint?

Is your alternator up for an extra 20 amps while idling?

Was wandering about the Volvo two relay controller for our cars, that's what I installed in my Volvo 780 when I converted to an electric fan. I hooked it up directly to the radiator as that's where the switch is. Worked like a charm.

Volvo 240 owners use the switch from a Saab 900, that's installed by cutting the upper coolant hose. Some Jaguar XJ owners use the same switch.
