Black sleeved PWM fan hub with 40cm or 50cm cable and Molex power connector

HETAI Digital Technology Co.,Ltd

HETAI Digital Technology Co.,Ltd 5 Port PWM Fan Hub 40cm or 8 Port 50cm

SKU CH-48QN-DSKXJ

Expands one motherboard PWM header to five or eight fans with 40 or 50 cm sleeved cable and Molex power

  • Connector TypeMicro USB to USB A
  • Expands one PWM header to five fans
  • 40 cm sleeved cable with Molex power input
  • Expands one PWM header to eight fans
  • 50 cm sleeved cable with Molex power input
  • Self-adhesive tape for simple case mounting

PWM Fan Hub Options

This PWM fan hub expands a single motherboard PWM header to control multiple cooling fans. Two versions are available: a five-port model with a 40cm cable and an eight-port model with a 50cm cable. Both draw 12V power directly from a PSU Molex LP4 connector. They suit builders who need to run several fans from one header.

RPM Signal Limitation

Only the first port labelled CPU Fan passes an RPM signal back to the motherboard. All other ports share the same PWM signal, so every connected fan runs at identical speed. Three-pin fans attached to the hub will spin at full speed because they lack PWM control. This design cannot report individual fan speeds or vary each fan independently.

Port Capacity and Power

The five-port hub comfortably handles up to five 12V fans while the eight-port version supports up to eight. Both rely on the PSU Molex connection for power headroom rather than the motherboard header. Builders needing more than eight fans or per-fan speed curves will require a different control solution.

Questions about this item

Should I pick the 5-port hub with the 40cm cable or the 8-port hub with the 50cm cable?

Choose the 5-port version if you need to power up to five fans and prefer the shorter 40cm lead. Choose the 8-port version if you need up to eight fans and can use the longer 50cm lead. Both draw 12V power from a Molex connector.

What happens to fan speeds when I connect multiple fans to the single motherboard PWM header?

All connected PWM fans follow the same signal from the motherboard header, so they run at identical speeds. The motherboard only reads the RPM from the fan plugged into the first CPU Fan port.

How does the Molex power input limit the hub's operation?

The hub takes 12V solely from a PSU Molex LP4 4-pin connector. This supplies power to every attached fan while the motherboard header only provides the control signal.
