The Nuvoton NCT7802Y is a hardware monitoring IC, capable of monitor critical system parameters including power supply voltages, fan speeds, and temperatures. The remote inputs can be connected to CPU/GPU thermal diode or any thermal diode sensors and thermistor, and also support direct CPU temperature control via the Intel® PECI3.0 interface.

The NCT7802Y can monitor up to 5 analog voltage inputs, 3 fan tachometer inputs and supports up to 6 multifunctional GPIO. The SMART FAN™ IV mode provides 4 sets of temperature setting points, and a PWM Fan output. It provides a quiet and easy way to implement cooling solution for maximum system safety and flexibility.
