The fan is a good choice. Be sure it covers at least 70% of the radiator so that you get the cooling you need.

The controller is fine but it is not necessary to go to that extent to control the fan properly. A temp probe will work just fine and and doesn't require any modifications or electrical work. The controller you list will give you an exact reading of the coolant and it does not disturb the radiator fins. An exact reading of the coolant temp is not necessary. All you need to do is set any controller so that the fan comes on just prior to the aux fan. You can't lower the engine operating temp with a controller as that is regulated by the thermostat. I was concerned about the probe in the fins. The probe happens to be just the right diameter to be a press fit in the fins but not great enough to damage the fins. Not saying you are making a mistake. I considered both but just so you know why I didn't go that route. I did fry a controller.


Any electric fan is mounted on the radiator and IMO should mount properly using the existing shroud.
