The ADT7463 controller is a complete system supervisor and multiple PWM fan controller for noise sensitive applications requiring active system cooling. It can monitor 12 V, 5 V and 2.5 V CPU voltages, plus its own supply voltage. It can monitor the temperature of up to two remote sensor diodes, plus its own internal temperature. It can measure and control the speed of up to four fans so that they run at the lowest possible speed for the lowest noise. An automatic fan speed control loop optimizes fan speed for a given temperature.
