Ive been mucking around trying to get my fans working properly.

I have seen adjustable dual fan controllers for sale and they start at about $150

After some research i realized its really easy to make one cheap and reliable.

Basically all you need (apart from wires n stuff) is two relays, two thermo switches at the temps you want, somewhere to put them, and a toggle switch that keeps the two earths seperate untill switched.

Wire + to ignition or acc.

Rather than being adjustable, fan operation is controlled by selecting the themoswitch temperature. Get one a little higher (or lower) than the other.
