9.1  Introduction
The PCA-6186's hardware monitor is designed with Winbond W83782D. 
Onboard security (OBS) functions monitor key hardware. They help you 
maintain your system's stability and durability. The PCA-6186 can moni-
tor 5 sets of system positive voltages, 2 sets of system negative voltages, 
CPU cooling fan speed, and CPU temperature. The positive system volt-
age sets which can be monitored include:
• CPU core voltage: 1.3 V ~ 3.3 V, according to Intel specifications.
• Transmission voltage from CPU to chipset: typically 1.8 V.
• Chipset voltage: typically 3.3 V.
• Main voltage: +5 V, +12 V.
The negative system voltage sets which can be monitored include:
• Main voltage: -5 V, -12 V.
