System Fan Speed; Vcore And Other Voltages; Shutdown Temperature; Frequency / Voltage Control - Advantech PCA-6009 User Manual

This shows you the current CPU FAN operating speed.

3.9.5 System FAN Speed

This shows you the current System FAN operating speed.

3.9.6 VCORE and Other Voltages

This shows you the voltage of VCORE, +1.5V, VCC3, +5V, +12V, -12V,
-5V, VBAT(V), and 5VSB(V).

3.9.7 Shutdown Temperature

The system will shut down automatically when the CPU temperature is
over the selected setting. This function can prevent CPU damage caused
by overheating.

3.10 Frequency / Voltage Control

3.10.1 CPU Clock Ratio

Key in a DEC number to set up the CPU Clock Ratio (Min=14; Max=17).
This item only shows up in special situations.

3.10.2 Spread Spectrum

This setting allows you to reduce the EMI by modulating the signals the
CPU generates so that the spikes are reduced to flatter curves. It achieves
this by varying the frequency slightly so that the signal does not use any
particular frequency for more than a moment. The choices are: "Dis-
abled," and "Enabled."
