So I put dual electric fans in and the thermal switch it came with is 185 on 160 off. I have a 180 thermostat so the fans aren't ever going to shut off. Just curious as to what others that gone electric fans have for thermal switches on and off. I'm thinking 205 on 190 off or 210 on 195 off. Any help would be great.

 

Get one that is adjustable would be my recommendation.

 

I've had so-so luck with adjustable thermal switches. So I went old-school with a toggle switch...put an "ON" indicator light in the dash...hooked into a hot-only-when-ignition-is-on wire...and called it a day. Since I'm the only driver, there's never a problem...simple is good.
