This header is for RGB LED strips of a CPU

fan.

The FAN RGB header supports CPU fans

with multi-color LED strips (12V/G/R/B)

and with a maximum power rating of 1A

(12V).

Before you install or remove any component, ensure that the ATX power supply is switched

off or the power cord is detached from the power supply. Failure to do so may cause severe

damage to the motherboard, peripherals, or components.
