3. HARDWARE SETUP 12) IDE Activity LED (2-pin IDELED) This connector supplies power to the cabinet's IDE activity LED. Read and write activity by devices connected to the Primary or Secondary IDE connectors will cause the LED to light up. 3. H/W SETUP Connectors ® TUWE-M TIP: If the case-mounted LED does not light, try reversing the 2-pin plug. IDELED TUWE-M IDE Activity LED 13) CPU (CPU_FAN), Chassis (CHA_FAN) Fan Connectors (3 pins) These connectors support cooling fans of 350mA (4.2 Watts) or less. Orientate the fans so that the heat sink fins allow 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 should be ground. Connect the fan's plug to the board taking into consideration the polarity of the connector. NOTE: The "Rotation" signal is to be used only by a specially designed fan with rotation signal. The Rotations per Minute (RPM) can be read directly from the ASUS iPanel or monitored using a utility such as ASUS PC Probe (or Intel LDCM.) WARNING! The CPU and/or motherboard will overheat if there is no airflow across the CPU and onboard heatsinks. Damage may occur to the motherboard and/or the CPU fan if these pins are incorrectly used. These are not jumpers, do not place jumper caps over these pins. CPU_FAN Rotation +12V GND ® TUWE-M SYS_FAN Rotation +12V GND TUWE-M 12-Volt Cooling Fan Power ASUS TUWE-M User's Manual 33
