I was wondering how long your e-fans stay on.

I have a new fluidyne radiator, new thermo, new rad cap, and a perma cool fan.

The fan is on a thermostat. If i don't have it set at a low setting it over heats. My car will over heat while driving down the highway if the fan isn't on (can't figure out what's wrong). All shields in place. If i set the thermostat to low it will stay cool.

 

i let mine run the whole time the car is on.. sometimes i let it run w/o the fan running when i first start it so the it warms up a bit quicker

but thats my situation

i dont have mine hooked up to a thermostat.. i have it hardwired to the battery w/ a main switch for it (for now)
