Main functions of ARGB PWM 2-in-1 8 way hub: expand 8-way 4-pin fan and 5v3-pin ARGB interface to solve the problem of motherboard fans Solve the problem of insufficient number of interfaces and focus on solving the problem of messy fan cables 8 Ports for Addressable RGB Lighting, if the motherboard has RGB synchronization function, lighting synchronization can be achieved 8-Channel PC Fan PWM HUB, provides a better power solution for motherboard cooling fans and CPU fans inside PC computer cases. It will effectively save your space, make cable management easier, and make the inner case tidy The back of the ARGB + PWM Hub PCB board has 3M adhesive for easy sticking on a flat place, and the transparent acrylic cover can block most dust Note: Only when the motherboard supports ARGB can the light be turned on. The red interface on the hub needs to be connected to a temperature-controlled fan. Other interfaces can be connected at will. However, when other interfaces are connected to three-pin fans, the speed will not be synchronized and will run at full speed. HATMINI PC Case Fan Hub + 5V 3Pin ARGB HUB The mainboard ARGB (3PIN) lighting control interface can be expanded to 8 to centrally control multiple RGB lighting devices The motherboard PWM speed adjustment interface can be expanded to 8, and the PWM speed adjustment of multiple 3pin/4pin fans can be centralized Features: 8-way chassis fan hub + 3Pin ARGB HUB suitable for PC desktop computer motherboard Effectively saves your space, makes cable management easier, and keeps the inner box tidy The red interface on the hub needs to be connected to a temperature-controlled fan, and other interfaces can be connected at will. However, when other interfaces are connected to a three-pin fan, the speed will not be synchronized and will run at full speed With acrylic transparent plate, 3M adhesive The SATA port is an auxiliary power port. When too many fans are connected, the power may be insufficient and the fans cannot operate at full speed. In this case, you can solve this problem by connecting this SATA port. Generally, this SATA port does not need to be connected. What you get: 1 x 8 channel 4 pin fan hub 1 x PWM cable 1 x ARGB female to female cable
