Asus H61M-K - Manual (Page 40)

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!
5. CPU and chassis fan connectors (4-pin CPU_FAN, 4-pin CHA_FAN)
Connect the fan cables to the fan connectors on the motherboard, ensuring that the
black wire of each cable matches the ground pin of the connector.
• The two fan connectors support fans of maximum 2A (24 W) fan power.
• Both the 4-pin CPU fan and 4-pin chassis fan are supported by the ASUS Fan Xpert
feature.
6. USB connectors (10-1 pin USB56, USB78)
These connectors are for USB 2.0 ports. Connect the USB module cable to any of
these connectors, then install the module to a slot opening at the back of the system
chassis. These USB connectors comply with USB 2.0 specification that supports up to
480 Mbps connection speed.
Never connect a 1394 cable to the USB connectors. Doing so will damage the motherboard!
The USB module cable is purchased separately.
