dual fan question
Anyone running a dual electric fan set up, do you have both fans kick on at the same time with the electric thermo switch or do you have one running all the time and the other kick on with the thermo switch? Thanks for any help!

Mine are both controlled by the same temp switch, using relays for each fan. They come on and off together. Be sure to have your alternator beefed up too at the same time.

The SPAL controller turns on one fan at low speed at the low temp threshold and has a wire to activate a second fan at the high temp threshold. The first fan would also go to high speed at the same time.
