Special features
Your mainboard is available in different configuration levels. Depending on the configuration, your
mainboard is equipped with or supports the features described in the following.
Silent Fan
A micro controller developed by Fujitsu Siemens Computers monitors and controls the
fans in the PC and thus prevents any unnecessary noise annoyance. Should the
processor become in spite of full turning ventilator too hot, then the processor clock
rate will automatically be reduced so that the system continues to run stably. The
microcontroller operates independently of the operating system and the processor.
Therefore the micro controller protects your PC reliably against overheating and loss
of data or even damage of the processor.
In addition, the microcontroller offers monitoring of, for example, system voltages
(12 V, 5 V, CMOS), opening of the case and a watchdog function.
SystemGuard
With SystemGuard the function of the onboard Silent Fan Controller is displayed.
SystemGuard indicates temperature, rotational speed of the fan and voltages, which
are measured by the Silent Fan Controller. Moreover the software offers various
setting options to optimise the noise level.
SystemGuard is a freeware-tool, which is
available on the internet.
Silent Drives
Hard disks and optical drives (CD-ROM, CD-RW, DVD etc.) are besides the fans
some of the greatest sources of noise in a PC. The
BIOS-Setup can be used to switch
these drives into a quieter mode.
Recovery BIOS
If an error occurs during a BIOS update (e. g. due to a power failure), the system
BIOS will be destroyed. All Fujitsu Siemens Computers mainboards are equipped with
a recovery BIOS. With it a destroyed BIOS can easily be restored. Exact instructions
are provided in the chapter "BIOS Recovery - Recovering System BIOS".
