Asus M2V-X - Manual (Page 46)

2-24 Chapter 2: Hardware information
Important notes on Serial ATA solution:
• The Serial ATA cable is smaller and more flexible, allowing easier
routing inside the chassis. The lower pin count of the Serial ATA
cable eliminates the problem caused by the wide, flat ribbon cables
of the Parallel ATA interface.
• Hot plug support for Serial ATA drive and connections is not
available on this motherboard.
• Install Windows
® XP Service Pack 1 or later versions when using
Serial ATA drives.
4. CPU, Power and Chassis Fan Connectors
(4-pin CPU_FAN, 3-pin CHA_FAN)
The fan connectors support cooling fans of 350mA~740mA (8.88W
max.) or a total of 1A~2.22A (26.64W max.) at +12V. Connect the fan
cables to the fan connectors on the motherboard, making sure that the
black wire of each cable matches the ground pin of the connector.
Do not forget to connect the fan cables to the fan connectors. Lack
of sufficient air flow within the system may damage the motherboard
components. These are not jumpers! DO NOT place jumper caps on
the fan connectors!
