Black 27 cm PWM fan splitter cable with one 4-pin plug and four 4-pin sockets

Ruth's sister

Ruth's sister PWM Fan Splitter 4pin 1 to 4 internal power cable

SKU CH-DFYA-4MKW1

A 27 cm PWM fan splitter cable connects four 4-pin fans to one motherboard header using 24 AWG tinned-copper wires with PVC insulation

  • Splits one 4-pin header into four fan connections
  • Extends fan reach with 27 cm cable length
  • Uses 1007 24 AWG tinned copper conductors for reliable power delivery
  • PVC insulation rated to 80 °C for safe operation
  • Compact 1.4 mm OD wire keeps cable routing tidy

PWM fan splitter for four fans

The Ruth's sister PWM fan splitter connects four 4-pin fans to a single motherboard header using a 27 cm cable. Builders who need more fan connections than their board provides can use this adapter to expand one CPU or chassis header into four without adding a controller.

Sustained load behaviour

Each of the four outputs carries the same PWM signal so all attached fans ramp together under continuous load. The 1007 24 AWG tinned copper conductors with 11 strands of 0.12 mm wire handle the combined current while the PVC insulation is rated to 80 °C.

Thermals noise and power draw

The cable adds negligible resistance so fan speed and noise remain dictated by the motherboard curve and the fans themselves. At 20 g the assembly is light enough not to strain headers and the 1.4 mm outer diameter keeps routing tidy in tight cases.

Questions about this item

Will the 1007 24 AWG tinned copper wires handle continuous power draw from four fans without overheating?

The cable uses 1007 24 AWG tinned copper conductors rated at 80 °C, so sustained load from four PWM fans stays within the insulation temperature limit.

Does my motherboard need a 4-pin PWM header to use this splitter?

Yes, the splitter plugs into a single 4-pin CPU or chassis fan header and provides four 4-pin connectors for the fans.

Can I connect three-pin chassis fans to the four 4-pin outputs on this cable?

Three-pin fans fit the 4-pin connectors and will run, but speed control reverts to voltage mode because the fourth PWM pin is not used.
