Five-port PWM fan hub for multi-fan builds

The EN-Labs 4PINHUB5P expands a single motherboard PWM header to drive up to five fans. It draws 12 V power directly from a PSU Molex connector, reducing load on the mainboard. The 45 cm sleeved black cable and 58 by 18 mm hub board fit inside most cases. Builders who need independent speed curves for each fan cannot use this hub.

Thermals noise and power delivery in daily use

All attached PWM fans follow one shared signal, so they spin at identical speeds. Only the first port labelled CPU Fan passes an RPM reading back to the motherboard. Three-pin fans connected to the hub run at full voltage continuously. Power comes from the PSU, not the header, so total fan current is not limited by the board.

Build quality connectors and mounting practicalities

The hub uses one TX4 female input and five TX4 male outputs on a 45 cm pigtail. A self-adhesive pad secures the 58 by 18 mm PCB to the chassis. Molex power input requires a free PSU connector. The fixed cable length may limit placement in larger enclosures.

Questions about this item

How do I install the 58x18 mm hub board and which header must receive the first fan?

Stick the hub to the case using the supplied self-adhesive tape, then plug the first fan into the port marked CPU Fan so the motherboard can read its RPM signal.

What upkeep will the PWM hub and its Molex power lead need over time?

No scheduled maintenance is required; simply check that the Molex connector and the five TX4 fan plugs stay firmly seated and free of dust during routine case cleaning.

What practical limit appears first when all five fans run continuously at 12 V?

The single motherboard PWM header drives every connected fan at the same speed, so the first limit is the shared RPM signal — only the fan on the CPU Fan port reports its speed back to the board.
