jinyue 4 Pin 1 to 3 PWM Fan Splitter Cable Sleeved 27cm

SKU CH-BYFH-3W42X

Splits one motherboard 4-pin header into three PWM fan connections with a single RPM signal, using 27 cm black sleeved 24 AWG cable

  • ColorBlack
  • One motherboard header powers three PWM fans with speed control
  • High-density 24AWG sleeved cable protects wires and simplifies routing
  • Single tachometer wire prevents conflicting RPM readings on the motherboard
  • Works with both 3-pin and 4-pin fans for broad compatibility
  • 27 cm length extends the 4-pin header to reach distant fans

1-to-3 PWM Fan Splitter

This 4-pin splitter connects three case fans to a single motherboard header, providing power and PWM speed control for each fan. The black sleeved cable measures 27 cm and uses 24 AWG conductors rated for 80 °C operation. It is designed for builders who need to expand cooling capacity without using additional headers.

Single RPM reporting header

Only one of the three male connectors carries the yellow tachometer wire, so the motherboard receives a single speed reading instead of three conflicting signals. The other two connectors supply power and PWM control without reporting RPM. This avoids BIOS warnings or fan-curve confusion when multiple fans share one header.

No extra accessories included

The package contains only the splitter cable itself; no mounting clips, cable ties or software are supplied. Builders must provide their own cable-management hardware and rely on the motherboard BIOS or fan-control software already present in the system.

Questions about this item

How does the single yellow RPM wire affect fan monitoring when three fans are connected?

Only one fan's tachometer signal reaches the motherboard, so the board reads a single RPM value instead of three separate readings.

What does the 4-pin PWM interface actually control on each attached fan?

The splitter passes the PWM signal to all three 4-pin male plugs, letting the motherboard adjust every connected fan's speed together.

Will the 27 cm sleeved cable reach from a standard ATX motherboard header to fans mounted at the front of a mid-tower case?

At 27 cm the cable suits short runs such as top or rear exhaust fans; front-mounted fans in larger cases usually need a longer extension.
