I cant remember what i had the hi/low fan settings at. I have dual oem fans with a digital dakota controller. On the low setting it runs one fan on high it runs both. What hi on/off temps and lo on/off temps should i run? I have a 180 tstat, Fluidyne, and high volume edelbrock waterpump.
I set mine to come on at 205. It shuts off at 195. My thermostat opens at 188. This 7* window is enough to give the fans a break while driving. So, it only comes on in traffic, if I have to sit for more than a few minutes. I could go low-high, but I don't. It's just on and off. Any time I can maintain 35-40 mph, the fans aren't needed.
