Black 4-pin PWM fan splitter cable, one motherboard connector to four fan connectors, 26.5 cm length

Ruth's sister

Ruth's sister 4-pin 1-to-4 fan adapter 26.5 cm internal power cable

SKU CH-K63Q-ZZJJE

Splits one motherboard 4-pin header into four fan connectors using 26.5 cm of 24 AWG tinned-copper cable rated to 80 °C

  • Connect four 4-pin fans to a single motherboard header
  • 5 cm length reaches CPU and chassis fan positions
  • 24 AWG tinned copper conductors rated to 80 °C
  • PVC insulation with 1.4 mm outer diameter for durability
  • Weighs only 20 g, adding minimal load to the motherboard

4-pin PWM fan splitter cable

This 26.5 cm adapter connects one motherboard 4-pin header to four 4-pin fans. It uses 1007 24 AWG tinned-copper wire with PVC insulation rated to 80 °C. The cable weighs 20 g and carries PWM control signals so all attached fans can be speed-regulated from a single header. Ideal for builders adding extra case or CPU cooling fans.

Suits builds needing multiple fans on one header

Builders who want to run several 4-pin PWM fans from a single motherboard connector will find this cable useful. It does not support fans that require independent speed curves per fan, and it cannot power fans that draw more current than the header allows. Users needing separate fan headers or voltage-only 3-pin control should look elsewhere.

Single 4-pin header splits to four 4-pin plugs

The decisive specification is the one-to-four 4-pin layout: one motherboard-style plug fans out to four fan-style sockets. This fixed topology means every connected fan receives the same PWM signal and shares the header’s current limit. Verify your motherboard header rating before connecting four fans.

Questions about this item

What connector spacing does the 26.5 cm 4-pin fan adapter need on the motherboard?

It plugs into a single standard 4-pin PWM header; the four fan leads spread from that one point, so no extra header spacing is required.

Which step do builders often miss when fitting the 1-to-4 PWM splitter?

Connect the blue PWM wire to the motherboard header so all four fans receive the same speed signal; the yellow, red and black lines carry power and ground only.

When should the 1007 24 AWG tinned-copper cable be replaced?

Replace it if the PVC insulation cracks, the 1.4 mm outer jacket frays, or the 4-pin connectors become loose after repeated fan swaps.
