Anyone who has run high-performance electric fans knows the routine: the engine hits a certain temperature, and the fans blast on at 100 percent until it cools down, only to repeat the cycle. PROFORM Parts is offering a smarter solution with its new PROFORM Brushless Fan Controller (P/N 69597), a digital, variable-speed unit that gives builders precise command over their engine’s cooling.

Designed exclusively for PROFORM’s brushless fans, the controller offers two powerful and distinct operating modes. The first is Temperature Mode, a “set it and forget it” function that many drivers will appreciate.

A user simply dials in their ideal engine temperature, and the controller automatically modulates the fan speed, ramping it up or down as needed to hold that temperature steady. This eliminates the noisy on/off cycling of traditional relays and maintains a more stable operating temperature, on the street or at the track. For easy installation, the kit includes both thread-in and push-in style temperature probes.

For those who want direct control, the controller’s second mode is Percentage Mode. This manual function allows the user to set the fan speed to a specific percentage, completely independent of the engine temperature. This is 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. The features of the PROFORM Brushless Fan Controller give the user complete authority over their cooling system.

Switching between the automatic and manual modes is simple, requiring just a long press of a button to toggle between them on the fly. Adjusting the settings is just as easy, with a long press used to lock in either a target temperature or a fan percentage. For added convenience, a short press on the temperature button switches the display between Fahrenheit and Celsius.

This new unit offers a modern, intelligent alternative to outdated on/off fan controls. By providing both automatic temperature regulation and full manual override, the PROFORM Brushless Fan Controller gives builders the precise, flexible control their high-performance cooling systems demand.
