I agree plus when its cold out you won't really even turn on the fan and on the freeway you also won't have the fan onm

Never use a manual switch to control a FAN. To many times they are ignored or forgotten and they will allow the engine to overheat. What we do is use a seperate temp sender in one of the heater hoses of a temperature of your choice and wire it in.

Bellow is a temp sender in my TC. The fans are factory set to come on @ 230* Way to high for my liking especially on a TURBO CAR. So i wired in this sender 180* and made a custom fitting so it looks factory.

Made this setup and wired it in to the IRCM. Fans now come on @ 180* every time!!!

i uses a switch just for a over ride in case if what in shown picture fails. has to be wired in just right though.

The way i have this wired it reverts back TO IRCM if the sensor goes south !!!!!

I use a temperature probe connected to a digital temp gauge, which outputs a signal to turn on my fans at any temperature I set it at, adjustable in one degree increments. The two fans come on in the low speed mode when this happens, and then turn off automatically when the temp drops a few degrees below the set temp.

I also wired a manual switch to turn the fans on high mode when I want/need extra cooling. The setup works well, but I do wish I had some sort of soft start feature.

I had the same problems as you did my tarus fan killed two fan controllers {start up amp draw was extremely high} then i swapped it out for a dual contour fan set up with a fan speed controller from flex a lite not only did it cool better it also gave me a ton of clearence for a v1 or v2 setup. pm me for part mumbers if you want

I just use a manual switch. Has Never overheated in the 5+years I've had it. I like that I have full control of when its on and forgetting it is not a problem.
