The Adjustable Fan Controller w/Pipe Thread Probe from DERALE is a precision engine cooling management solution designed for vehicle builders, performance enthusiasts, and mechanics who demand reliable temperature regulation without factory restraint. This adjustable fan controller allows you to dial in exact cooling activation points between 150–240 degrees Fahrenheit, giving you complete authority over when your electric cooling fan engages. Whether you're running a custom engine swap, upgrading a classic hot rod, or fine-tuning a performance build, this controller eliminates the guesswork and complexity of factory fan logic.
The system operates through a 3/8 inch NPT (National Pipe Thread) temperature sensor that mounts directly into your engine block, radiator, or custom cooling passages for accurate real-time readings and fast response. DERALE engineered this controller with a robust 25-amp relay, providing sufficient capacity for single or dual electric fans while maintaining clean electrical isolation from ignition circuits. The included wiring harness ships complete and ready to integrate, eliminating troublesome point-to-point splicing and reducing installation time. Adjustability via a simple dial lets you raise or lower the activation threshold on the fly—critical when tuning carbureted engines, swapping radiators, or optimizing fuel injection parameters during dyno sessions.
This controller excels in street rods, restorations, engine conversions, and any application where OEM fan control conflicts with custom cooling design. Mechanics and fabricators appreciate the plug-and-play harness, which reduces wiring errors on complex builds and shortens commissioning time. The pipe thread probe design ensures secure mounting without drilling additional holes, preserving block integrity on vintage or valuable engines. Compact dimensions (4.5 x 2.5 x 7.5 inches) allow flexible mounting in tight engine bays, while the lightweight construction (0.95 lbs) means minimal parasitic load and vibration isolation concerns.
