Application Note 8-20: Using the Hardware Monitor Feature in SMSC Super I/O Devices
The EMC6D100 & EMC6D101 are environmental monitoring and control devices with automatic fan control capability for PCs and embedded systems. These ACPI compliant devices provide hardware monitoring for up to eight voltages and three thermal zones, measure the speed of up to four fans, and control the speed of multiple DC fans using three Pulse Width Modulators (PWM). Note that it is possible to control more than three fans by connecting two fans to one PWM output.
