About this manual

The ADM1030 is an ACPI-compliant two-channel digital thermometer and under/over temperature alarm designed for use in computers and thermal management systems. It is optimized for Pentium III processors, allowing system designers to reduce temperature guardbanding and increase performance. The device features a Pulsewidth Modulated (PWM) Fan Control output that varies the duty cycle between 33% and 100% to control fan speed smoothly.
