Review on Spal 30100435 10" Curved Blade Puller Fan: Enhance Cooling Performance with Precision by Bryan Fields

I installed 3 of these on my 01 Cherokee with the Dirtbound Offroad Shroud. They definitely move air and are quieter than the old mechanical fan. I am using a Dakota Digital PAC-2750 fan controller. One fan turns on at 205, the next at 210, and the third fan is controlled by the factory computer and relay to turn on at 217. Fan 3 hasn't turned on yet because the first two keep my 4.0 cool. . On the track, or in the scorching heat of next summer, I suspect the third will step in when needed. As for the booster boost, I have a regular 117a alternator and there are no problems. I suppose fan staggering helps a lot with this, and I recommend the PAC-2750 for your controller.
