Temperature / system monitoring
Temperature and system monitoring aim to reliably protect the computer
hardware against damage caused by overheating. In addition, any unnecessary
noise is also prevented by reducing the fan speed, and information is provided
about the system status.
The following functions are supported:
Temperature monitoring
Measurement of the processor and the system internal temperature by an
onboard temperature sensor, measurement of the ambient temperature by a
I
2
C temperature sensor.
Fan monitoring
The CPU, power supply unit and system fans are monitored. Fans that are no
longer available, blocked or sticky fans are detected.
Fan control
The fans are regulated according to temperature.
Sensor monitoring
The removal of, or a fault in, a temperature sensor is detected. Should this
happen all fans monitored by this sensor run at maximum speed, to achieve the
greatest possible protection of the hardware.
Voltage monitoring
When voltage exceeds warning level high or falls below warning level low an
alert will be generated.
Cover monitoring
Unauthorised opening of the cover is detected, even when the system is
switched off. However, this will only be indicated when the system is switched
on again.
