7.CPU, chassis, and optional fan connectors(4-pin CPU_FAN, 3-pin CHA_FAN1–3, 3-pin PWR_FAN, 3‑pin OPT_FAN1–3)

The fan connectors support cooling fans of 350 mA–1000 mA (24 W max.) or a total of 1 A–3.48 A (41.76 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.
