• ADT7490EBZEVB, Evaluation Board for the ADT7490 is a thermal monitor 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 including series resistance cancellation and monitors CPU temperature with a PECI interface. The ADT7490 can drive a fan using either a low or high frequency drive signal and measure and control the speed of up to four fans so they operate at the lowest possible speed for minimum acoustic noise
