System/CPU Cooling Fan Connector (J16/J17)
These added connectors allow the fans to draw their
power from the mainboard instead of the disk drive
connector. some systems have all the disk drive power
connectors in use.
APTC
Technology
APTC (Active Processor Temperature Control) Technology
Upon overheating, the system can reduce the CPU's speed to prevent burn-out. When
CPU temperature is over a default setting of 75+/-10°C (programmable via BIOS), the
system will give a warning signal and the CPU's speed will decrease to an arbitrary
speed. The thermal warning message can be enabled/disabled via the CPU Warning
Temperature function in BIOS's Power Management Setup menu.
Management Extension Hardware for
SMART
Technology
(Upgrade Kit)
Management extension hardware provides low-cost instrumentation capabilities. The
hardware implementation is a single-chip ASIC located in the CPU cooling fan. Its
features include an integrated temperature sensor, fan speed sensors, and power
supply voltage monitoring to detect levels above or below acceptable values. Please
constact your mainboard dealer to obtain the FAN78-SMART technology upgrade kit.
More details about this kit can be found in Appendix III of this manual.
Infrared Connector (J13)
If you set COM2 Mode in BIOS's Integrated Peripherals
menu to ASK IR or IrDA, the COM2 port will support
IR functions.
