The Mishimoto Pulse-Width Modulation (PWM) fan controller provides precise engine temperature control by adjusting fan speed from 0–100% based on coolant temperature. It monitors and modulates fan output, includes soft-start to reduce startup amp draw and noise, and can drive multiple fans up to a 50 A capacity with an 80 A relay. Safety features include an automatic resetting circuit breaker, thermal shutdown at 195°F, and an override circuit for A/C or manual use; the unit is backed by Mishimoto's Lifetime Warranty.
