Two interfaces on the left, the one on the left is the light 5V ARGB motherboard synchronous interface, if you want to use the synchronous direct connection, press the MB key on the remote control for 6 seconds to adjust the synchronization; the one on the right is the FAN running at full speed when the motherboard temperature control interface is not connected, and the motherboard controls the speed after being connected, it is recommended to connect the CPU FAN interface. Four temperature control center line on the left and right sides, the red temperature control interface must be connected to the temperature control fan, the light interface can be freely connected, the for SATA interface on the right must be connected The two‑in‑one controller is equipped with a remote control, a mainboard synchronization cable, and a control cable temperature. If the motherboard does not support synchronization, you can use the remote control and do not need to connect the synchronization cable. Direct output with power interface, more expressive and efficient. The hub has a motherboard RGB synchronization function (for light bars), PWM function and fan power. Support synchronous mainboard control and remote control of lighting effects. 1 to 8 fan multi‑port for SATA hub power supply 12V 4‑pin PWM ARGB addressable distributor for PC LED light cooler control adapter. 8 ARGB ports (5V 3pin), 8 fan ports (4pin) PWM function, 1x3 pin lighting 5V ARGB motherboard synchronization, 1 motherboard temperature control port, for SATA power supply, and the remote control button is 21 keys.
