The function of the Arctic Case Fan Hub is as simple as it is ingenious: With it, up to ten 4-pin fans can be controlled out-of-the-box with a PWM signal . To do this, connect the supplied 4-pin PWM cable to a 4-pin fan header on the motherboard and connect the SATA power cable to the power supply unit. Now up to ten 4-pin fans can be connected directly to the hub and controlled via a PWM signal.The Arctic Case Fan Hub at a glance:- Arctic hub for ten 4-pin fans- Controllable via the PWM signal from the mainboard- Power supply via SATA cable- Cable and mounting material are includedPWM control via mainboardWith the 10-port fan hub from Arctic , up to ten 4-pin PWM fans can be operated and controlled simultaneously via just one 4-pin connector on the mainboard . The fan hub is connected to a free 4-pin port on the mainboard and connected to the power supply via SATA power. Thats it. All connected fans are now controlled via a PWM signal. The speed signal of the first fan is read out and passed on to the mainboard.The separate power supply via SATA power cable ensures a continuous flow of current and prevents overloading of the 4-pin pot on the mainboard. For mounting in the housingtwo self-adhesive Velcro surfaces and magnetic tapes are included . With these, the hub can be placed flexibly - for example on the back of the MB tray.Technical details:- Colour: BlackConnections:- 1x SATA power (power supply unit)- 1x 4-pin PWM (mainboard)- 10x 4-pin PWM (fan)Scope of delivery:- PWM hub- 1x 4-pin PWM connection cable (mainboard)- 2x self-adhesive magnetic tape- 2x self-adhesive Velcro tape
