Flex-a-lite variable speed controllers attach on or near the electric fan, sensing coolant temperature via a radiator probe or temperature sending unit. They set fan speed from 60 to 100 percent, depending on the built-in thermostat's setting. The thermostats have a range of 160-220 degrees F. The variable speed controllers allow greater control over engine temperature, which helps to reduce charging spikes and current load on the charging system. They keep the fans running for 30 seconds after your vehicle is turned off.

Simple and Works!

After burning out several more complicated fan controllers that were less user friendly, I bought this and after about 25 minutes I had a fully functioning and cycling fan to cool my rx7.

This controller does exactly what it's suppose to do I hooked dual fans in my 82 cutlass and now 350 doesn't go over 195 and I'm in Texas heat.

Fan controller

Summit RacingSummit Racing Verified Purchase

Works good, however in my view the controller should have a broader temp band. The unit seems to start and stop in a 10 deg F range fully adjustable by the user. It would be nice if that could be 15 or so, I think it would prevent some hunting of the engine temp. The fans would run a little longer each time they started but may have time to catch the temp rise of the engine and keep it closer to set point. Update, I gave up on this controller because it is not stable and consistent with temp settings. When the product is cool it works much better then hot. While hot under the hood the controller on/off varies 10-15 deg and very randomly you never know when it will turn the fans on. I routinely would see fans on 10-15 after the set point and off before set point. Would not recommend. ...read more
