Pump Power Header
The C9X299-PG300F has one +12V header for optional CPU liquid cooling systems. When
using a liquid cooling system, attach the pump power cable to the 12V_PUMP_PWR1 header.
RGB LED Strip
The JP_RGB1 and JP_RGB2 headers provide RGB LED strip support. To install an LED
strip, align the arrow on the LED strip connector to 4-pin RGB header (+12V, G,R,B). This
will allow you to control the RGB LED strips with the motherboard's software and enhance
the interior look of your case.
