Arctic Case Fan Hub Arctic Case Fan Hub is a 10-port PVC fan concentrator with SATA power input. It allows to separate one PWM connector into nine PWM fans. Compatible with 3pin pin 4pin fans. Fully modular cable management. Arctic Fan HUB has been equipped with a magnet on the bottom so you can easily attach it to the housing. SYNCHRONIC TERMINATION OF VENTYLATORS The centre of the housing fan can be placed in the housing. It is connected to the motherboard with only one cable. This means that you can handle without many additional cables and arrange them freely in the invisible part of the housing. The PWM signal you set is transmitted synchronously to all fans connected to Case Fan Hub. The rotations of the first fan socket are read and returned to the system. Improve the ventilation of your housing Even if you do not have enough fan sockets on the motherboard, this HUB from Arctic will expand the available number by 9 additional sockets into computer fans. Fans are powered directly from your power supply via SATA Power plug. As a result, there is no loss of voltage at the fan speed and it is possible to change the fan rotations smoothly through the PWM signal.
