The ADT7490 is a thermal supervisor and multiple PWM fan controller for noise-sensitive or power-sensitive applications requiring active system cooling. The ADT7490 includes a local temperature sensor, two remote temperature sensors with series resistance rejection to monitor CPU temperature through the PECI interface. The ADT7490 can drive fans with low or high frequency drive signals and measure and control the speed of up to four fans to run at the lowest speed for maximum noise reduction.
