5 . CPU and system fan connectors (4-pin CPU_FAN1/2, 3-pin REAR_FAN1/2, 3-pin FRNT_FAN1/2) The fan connectors support cooling fans of 350 mA ~ 740 mA (8.88 W max.) or a total of 2.1 A ~ 4.44 A (53.28 W 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. Insufficient air flow inside the system may damage the motherboard components. These are not jumpers! Do not place jumper caps on the fan connectors! ® P5CR-LS GND FANPWR2 FANOUT4 CPU_FAN2 FRNT_FAN1 REAR_FAN1 REAR_FAN2 FRNT_FAN2 CPU_FAN1 P5CR-L(S) Fan connectors REAR_FAN1 Rotation +12V GND CPU_FAN2 FANOUT4 FANPWR2 GND FRNT_FAN1 Rotation +12V GND REAR_FAN2 Rotation +12V GND CPU_FAN1 FRNT_FAN2 Rotation +12V GND 6 . Hard disk activity LED connector (4-pin HDLED1) This connector supplies power to the hard disk activity LED for add-on cards such as SCSI or RAID cards.
