Derale PWM Fan Controllers

Take Control of Your Vehicle's Cooling

Derale PWM Fan Controllers use modern-day Smart Technology to control your engine's cooling system electric fan speeds and continuously monitor your engine's temperature. These controllers increase vehicle cooling efficiency while also reducing the amps used to do so. They provide a more accurate reading for your cooling system, react 50-percent quicker than typical brass probe-style sensors, eliminate harmful amperage spikes, and reduce fan noise.
