I do believe though that a good mechanical fan system will outperform my setup on the highway. I do also need to add a second alternator though because each fan draws 19amps and are controlled through a 'Derale' twin thermo switch system roughly 10F degrees apart. So if I need to winch and both fans are on I'm stuffed at the moment. Other cooling mods underway should see the second fan almost not needed I'm hoping.
Gotta head to dinner now so can send some pics tomorrow if you need mate, Cheers!
