The Derale Dual High-Output, Electric Radiator Fan, part # D16825, is a single speed system and both fans operate at the same time.

There are options available for control of the fans you may be interested in. The first is to use a switch like the Derale Lighted On/Off Switch, part # D16740. This switch is a simple toggle switch that allows you to easily turn your fans on or off.

If you wish to install an automatic system, I recommend part # D16789. This will turn the fan on or off per the temperature you set between 150 F and 240 F. This has a power-saving feature that shuts off the fan when the fluid temp falls below a determined temperature. This includes the radiator probe and installation kit.
