The Case Fan Hub comes equipped with adhesive pads and magnetic strips, which lets you place it anywhere in the case. It connects to your motherboard with only one cable and powered via SATA. This way, you can do without many additional cables and position it freely in the hidden part of the case.
Your set PWM signal is passed on synchronously to all fans connected to the Case Fan Hub. The RPM of the first fan slot will be read out and returned to your system.
Even if you don't have enough fan headers on your mainboard, the case fan hub expands your system by 9 more case fan slots.
The fans are powered directly from your power supply via SATA Power. As a result, there is no voltage loss at the fan speed and smooth, smooth operation is made possible.
