* If 3-pin non-PWM fans are connected to this fan hub, this fan hub CANNOT give them extra PWM function. They will run at FULL SPEED. * If 4-pin PWM fans are connected to this fan hub, DUTY RATIO of all PWM fans can be adjusted at the same time. That is, all PWM fans will run at the same DUTY RATIO. Only speed of Fan 1 can be identified by the system. * Capable of connecting to 10 PC fans simultaneously for cooling the computer system. * Powered by a stable SATA connection to the system PSU for up to 10 fans. * Velcro and screw mountings applicable for the tower interiors.
