Two black braided nylon PWM fan splitter cables with 4-pin female to 4-pin and 3-pin male connectors

SXDOOL

SXDOOL 10 inch 1 to 2 PWM Fan Splitter Cable (2 Pack)

SKU CH-PF1X-KNY57

Splits one 4-pin PWM header into two fan connections with a 4-pin male and 3-pin male for mixed fan types, supplied as a pair of 10 inch braided cables

  • Durable braided nylon sleeve protects wiring for longer life
  • 10 inch length gives extra reach inside larger cases
  • 4-pin PWM and 3-pin fan compatibility on one splitter
  • Female 4-pin connects to motherboard, two male headers drive two fans
  • Two splitters included to expand cooling in a single purchase

Dual PWM splitter for 3-pin and 4-pin fans

This two-pack connects two case fans to a single motherboard header using a 4-pin female, a 4-pin male and a 3-pin male connector. The 10 inch braided nylon sleeves give extra reach inside larger enclosures. Builders who want independent speed reporting from both fans should note only the 4-pin male leg carries the tachometer signal.

Sustained airflow control through shared PWM signal

Both fans receive the same pulse-width modulation duty cycle from the motherboard, so speeds ramp together under continuous load. The 3-pin leg runs at the voltage defined by that PWM curve but cannot report its own RPM back to the board. Cable resistance over the 10 inch length is negligible for typical case-fan currents.

Replaces single-fan headers or short Y-cables

Use these splitters when a board lacks enough fan headers or when existing cables cannot span the distance to top or rear mounts. The jump is worth it if you need two fans on one header and can accept shared speed control with tach feedback from only one fan. Buyers who require per-fan speed curves or monitoring for each fan cannot meet that need with this splitter.

Questions about this item

Does the 4-pin female header pass PWM speed signals to both the 4-pin and 3-pin male connectors?

Yes, the 4-pin female passes the PWM control wire to the 4-pin male, while the 3-pin male receives voltage control only.

What motherboard header do I need to plug this splitter into?

A standard 4-pin PWM fan header on the motherboard is required for the 4-pin male connector.

Can I connect a 3-pin fan to the 4-pin male port and still get speed control?

A 3-pin fan on the 4-pin male will run at variable voltage but without the PWM signal wire.
