Plug in the CPU fan cable to the 3-pin
CPUFAN
connector. If you have chassis fan, you can
also plug it on
SYSFAN1
or
SYSFAN2
connector.
5. Setting CPU Voltage & Frequency
4. Connecting IDE & Floppy Connectors
3. Installing CPU & Housing Fan
Note: Some CPU fans do not have
sensor pin, so that they cannot
support fan monitoring.

Note: With CPU speed changing rapidly, there might be faster CPU on the market by
the time you received this installation guide. This table is kindly for your references
only.
Tip: If your system hangs or fails to boot because of overclocking, simply use
<Home> key to restore the default setting or you can wait the AOpen “Watch
Dog ABS” reset the system in five seconds and system will auto-detect
hardware again.
Warning: nForce3 chipset supports 200MHz system clock and
66MHz AGP clock; higher clock setting may cause serious
system damage.
