Ford used a 2 spd fan (Taurus, etc) that many rodders use, and I recall Ford and Volvo have ties, so could be the same or similar.

Several people on the old Mopar sites I visit have tried replacing their mechanical fan with an electric and realized poorer cooling. It is hard to beat a mechanical fan/clutch that is working. There are more efficiency losses in running electric. It will be interesting to see your results.

In our M-B, the electric fan is just for the AC condenser, and does that job fine when the fan runs, but the control system seems reluctant to turn it on. RollGuy re-designed so it always turns on when the AC clutch is engaged, though it then runs even when not needed (highway). Perhaps a redesign so it turns on w/ AC clutch plus a temp switch set lower than the standard PN would perfect it.
