BIW1A
series
~27~
CPU & Power Supply Fan Connectors (3-pin FanPWR)
These connectors support cooling fans of 500mAMP (6 watts) or less.
Position the fans so that the heat-sink fins allow the airflow to go across the
onboard heat-sink(s) instead of the expansion slots. Depending on the fan
manufacturer, the wiring and plug may be different. The red wire should be
positive, while the black one should be grounded. Connect the fan's plug to
the board, taking into consideration the polarity of this connector.
The CPU and motherboard will overheat if the hot air generated
by the CPU does not flow across the onboard heat-sinks, and the
CPU fan and motherboard can be damaged if these pins are used
improperly.
2.3-4 Installing the Motherboard
The
BIW1A
series
motherboard complies with the specifications for an ATX
board, so you can also install this kind of board into a full-size ATX case.
Some features on the motherboard are implemented by cabling connectors on
the motherboard to indicators and switches on the system case. Ensure that
your case supports all the features required. The
BIW1A
series
motherboard
can support one or two floppy diskette drives and four enhanced IDE drives.
Ensure that your case has sufficient power and space for all the drives that
you intend to install.
!
Caution:
Make sure that you have already installed the system
board components like the CPU and memory, and have set the appropriate
jumpers before you proceed.
The "rotation" signal is to be used only by a specially designed fan with a
rotation signal.
