Proform Parts Engine Cooling Fan Controller

Proform Parts Engine Cooling Fan Controllers: Intelligent Temperature Management

Proform Parts has built a well-earned reputation in the high-performance aftermarket over more than 30 years, and their engine cooling fan controllers reflect exactly the kind of engineering-forward thinking the brand is known for. Rather than accepting the limitations of simple on/off thermostat switches, Proform has developed a lineup of fan controllers that treat temperature management as the precision science it is.

Beyond On/Off: Proform's Variable-Speed Advantage

The fundamental difference between a Proform fan controller and a basic switch comes down to how each handles the relationship between engine temperature and fan speed. Traditional controllers take a blunt approach: many fan controllers turn the fan on to full power when the engine is getting too hot and power it off as soon as the temperature is sufficient, wasting energy and shortening part life. Proform's second-generation digital variable-speed design takes a smarter path. Proform's Variable Speed Controller monitors engine temperature and keeps it consistent by running the engine's single or dual fans at the optimum RPM needed to maintain the temperature.

The fan controller processes a temperature signal from the radiator from a brass probe (push-in and thread-in are included). As the engine approaches the maximum desired temperature, the controller soft-starts the engine fan(s) and slowly ramps up to the required speed needed to maintain that temperature. The practical result: Proform's 2nd Gen. controller substantially reduces amperage spikes, excessive fan wear, and undesired fan noise that many other fan controllers actually cause.

Key Technical Features

• The controller is designed to handle up to a total of 60 amps, and employs a gradual ramp up to minimize amperage spikes during turn on.
• The controller can be used with single or dual fan setups.
• The weather-resistant billet aluminum housing with bright digital display ensures easy setting by simply pushing + or – to set the temperature.
• After setting your temperature point, the fan(s) will begin to run slowly when the engine temperature is 6 degrees below the set temperature, and will increase in speed as the engine temperature approaches the set temperature.
• Fan activation is adjustable between 150 and 240 degrees F.
• Proform fan controllers are approved for both street and racing applications.

The Brushless Fan Controller: Proform's Latest Evolution

Proform Parts offers its Brushless Fan Controller (P/N 69597), a digital, variable-speed unit that gives builders precise command over their engine's cooling. This controller introduces a dual-mode operation approach. The unit offers two modes: an automatic mode that holds a set temp, while a manual mode gives you full control. The controller's "Percentage Mode" allows the user to set the fan speed to a specific percentage, completely independent of engine temperature — perfect for specific situations, like turning the fans down in a drive-thru line or cranking them to full power in the staging lanes before a pass.
