Doesn't do what it makes out
1 of 5 found this helpful It only actually controls the speed of one PWM fan which is directly powered by the motherboard. I wanted a hub that is sata powered so I don't overload a mobo header but still has RPM control. This product said that it takes the RPM of the header and then can apply it across to all the other connected fans, it cannot. It can power 9 fans by SATA at full speed (making their PWM pointless) and one fan exactly as if it were connected to the mobo (making the hub redundant)
