Depending on which Spal fans you have you, you might be able to use one C6 fan controller for both. If the combined amp draw of both fans exceeds 32 amps, you will need two C6 fan controllers.

By the time you get two controllers (unless you want to go junk car hunting...the Ford Fusion used the same controller) you might be better off selling the fans you have and going with the new brushless fans.

The C7 fan should fit a Chevelle radiator size well or perhaps the Chevrolet Volt dual 12" setup. The new fans have the controllers built in. I have several customers using the C7 fan and Holley EFI. The C7 fan is 600 watts and the Volt fans are 300 watts each.

I plan on updating the GTO this spring and will likely use the Volt fans.
