Maradyne MFA136 PWM Fan Controller w/ Temp Sensor Half Speed

The Maradyne MFA136 PWM Fan Controller with temperature sensor delivers advanced, efficient control of electric radiator cooling fans for improved engine temperature management and performance. Utilizing pulse width modulation (PWM) technology, this controller provides a soft half-speed start that reduces electrical load and extends fan life, then smoothly ramps up to full speed as cooling demand increases. The adjustable temperature sensor (1/8" NPT with 1/2" adapter) allows precise control over fan activation, while the built-in potentiometer lets users fine-tune the start temperature to match their setup. Designed for universal fitment, the compact unit mounts easily to core supports or other metal surfaces and controls fans up to 225 watts. By maintaining full fan operation until coolant temperature drops by approximately 20 degrees, the MFA136 ensures consistent, reliable cooling performance for street, performance, and off-road applications.
