Z97I-PLUS Fan connectors
• DO NOT forget to connect the fan cables to the fan connectors. Insufficient air flow
inside the system may damage the motherboard components. These are not jumpers!
Do not place jumper caps on the fan connectors!
• Ensure that the CPU fan cable is securely installed to the CPU fan connector.
• The CPU_FAN connector supports the CPU fan of maximum 1A (12 W) fan power.
• The CPU fan connector detects the type of CPU fan installed and automatically
switches the control modes. To configure the CPU fan's control mode, go to
Advanced Mode > Monitor > CPU Q-Fan Control item in BIOS.
• The chassis fan connectors support DC and PWM modes. To set these fans to DC or
PWM, go to Advanced Mode > Monitor > Chassis Fan 1/2 Q-Fan Control items in
BIOS.
