hey guys great site new here have visited a few time but im here now question just finished installing my new efans and not sure where I need to set the controller temp to turn the fans on 06 screw 5.4 flex fuel the truck usually runs 194 to 196 per my edge programmer so I set the fans to come on at 194 they drop the temp to 192 and shut off should I set the temp a little higher so that they don't run all the time when im driving thanks in advance

 

i have mine set to come on at 196

 

Thanks for the quick reply I set them for 196 and as long as I'm driving they dont turn on and temp stays around 194

 

Set mine for 200. It was my understanding that the 4.6 runs good @200.
My temp sensor is near the radiator outlet. So I am sensing the water temp going into the engine, not reading the temp coming out. The fans rarely run. Have thought about lowering the temp. Anyone know an optimum temp for the 4.6? I believe the thermostat is 192.

 

Anyone know what the safe range of temperature is for the 5.4. My setup generally stays around 196 except in stop and go traffic it seems to hear up as high as 206 sometimes. The efans usually get it down to 196 pretty fast but I have thought about setting there activation temp a little lower.
