Manage Multiple FansIf your motherboard lacks fan interfaces, our PWM fan hub is the neat and tidy way to expand. The 12V fan controller accurately controls 3 pin/4 pin fan speed from a single case input. Power Supply and Temperature ControlIt can be directly powered by the power supply, which can reduce the load pressure of the motherboard. The CPU fan 4-pin interface connected to the motherboard is responsible for speed measurement and speed regulation. 8-Way Chassis Fan HubThe CPU fan is connected to the RED port of the controller; the fan installed can be connected to FAN 2-8; the motherboard detects the speed of the CPU fan and adjusts the speed of all fans as well. So FAN 2-8 does not have the function of feedback speed, only PWM speed regulation function. Easy To InstallThe adhesive on the back can be used to fix the hub in the chassis, tool-free installation, also 3 fixing screw hole in the PCB to facilitate fixing to a part of the chassis, and not easy to drop. Other AccessoriesEquipped with 8pcs self-locking nylon cable ties, you can use to fix the PCB and organize the bundled and installed fan lines. Equipped with a 2Pin to 4Pin PWM fan control cable: 2Pin is terminated to the controller 2-pin socket, and 4Pin is terminated to the CPU PWM 4-pin fan socket of the computer motherboard.
