Connect the noiseless connector (RCXX) to the FB123 fan’s 3-pin connector. Then, connect
the noiseless connector to the motherboard’s CPU fan connector (3-pin) as shown in FIG. 9.
Note 1) The separate speed noiseless connector will be on sale afterwards (See FIG. 10). Refer to
the manual when using it.
Turn on the computer after the assembly is finished.
If an alarm sound is generated to indicate that the rotation of the CPU fan is slow after the system
monitoring program starts to operate during booting of the computer, please unplug the noiseless
connector from the fan and set “CPU Fan Detected” to “Disable” in the BIOS settings, or set the
slowest rotation of the CPU fan in the system monitoring program, to less than or equal to
1500 RPM. Then, reconnect the noiseless connector to the CPU fan connector.
Note 2) Some motherboards do not boot if the RPM of the CPU fan is not measured. In this case,
please boot the computer with the Cooler fan in Normal Mode, i.e. after removing the
noiseless connector. If the BIOS settings are updated, Silent Mode can be used by
reconnecting the noiseless connector. For information on updating the BIOS, please refer
to the motherboard manufacturer’s web site.
