9.3 Fan Power Supply [STS100C (Combo) and
STS100A (Active) Solutions]
The 4-pin PWM controlled thermal solution is being offered to help provide better
control over pedestal chassis acoustics. This is achieved though more accurate
measurement of processor die temperature through the processor’s Digital Thermal
Sensors. Fan RPM is modulated through the use of an ASIC located on the baseboard
that sends out a PWM control signal to the 4th pin of the connector labeled as Control.
This thermal solution requires a constant +12 V supplied to pin 2 of the active thermal
