8-Port PWM Fan Hub
The EN-Labs 11-001-409RDX expands a single motherboard PWM header to support eight fans. It draws 12V power from two Molex connectors on the PSU, reducing load on the board. A 40cm PWM cable is included for the motherboard connection.
Builders needing simultaneous speed control
The hub synchronises PWM fans so they spin at the same speed. Three-pin fans run at full speed only because they lack a PWM signal wire. Only the red header returns an RPM signal to the motherboard; the remaining ports do not report speed.
Red header must connect to a PWM fan
If the red port is left empty or attached to a non-PWM device, the hub locks to full speed and PWM control is lost. Eight onboard capacitors protect each output channel. Self-adhesive backing secures the PCB inside the chassis.

Questions about this item
What does the 12V/2A rating mean when I connect eight fans?
The hub can supply up to 2 A per channel from the PSU, so eight 12 V fans drawing up to 2 A each can run simultaneously without overloading the motherboard header.
How does the dual Molex power input limit the hub in practice?
Two Molex 4-pin connectors deliver 12 V power from the PSU, capping total output at the combined Molex rating and removing load from the motherboard.
What space and mounting options does the board need inside the case?
The PCB includes a self-adhesive pad for sticking to a flat surface, and the 40 cm PWM lead reaches most motherboard headers.
