Features: 1.The power supply is powered by the SATA interface, supports 10 4PIN fans to start at the same time, solves the lack of motherboard interfaces, and centrally processes fan wires. 2.This PWM interface is connected to the motherboard CPU FAN interface through the PWM cable. The red interface is dedicated to the CPU fan, and the black interface is the regular PWM fan interface. 3.The 10-way hub can support 10 fans with 3pin/4pin interface, and after connecting the PWM temperature control and speed control cable, the fan can be temperature-controlled and speed-regulated. 4.Equipped with a PWM cable with a length of 40CM, which can support the back line. After the PWM cable is connected to the main board, the temperature control and speed can be controlled by the main board. 5.The EVA double?sided tape on the back can fix the computer fan hub on the chassis. specification:Item Type: SATA Interface Fan Hub Suitable For: 12V 4Pin Fan 10 PWM ports 4pin CPU cooler/chassis/cooling fan hub chassis, 10 12v 4-pin pwm fan hub controllers, for molex power, 1.64ft rpm feedback cable.
